Im working on a middle size project, using WPF. Need DataGrid, suitable for the client: fast, customizable, beautiful. Which component suite do you suggest from your practice?(for example Devexpress's, telerik's, Infragistics's and etc)
I have used Telerik data grid in the past and it seemed to have the least hastles for me compared to others I have had a look at.
However I can pretty much put my money on it that someone else would feel that Telerik's control wasn't great and that Infragistics was better etc. - so I suggest that you maybe download the trials and test them for your specific scenario.
"Fast, customizable, beautiful." - try Xceed's (I work there), there's a no-install XBAP demo. Also supports asynchronous data virtualization and smooth scrolling and other stuff no other datagrid does.
Xceed DataGrid for WPF main page
XBAP demos page
I've been evaluating Xceed for a few weeks now and while it is powerful it's dog slow when placed in a tab control switching between tabs. 30 seconds to open a tab on a large data set. The forum on their website seems to suggest this is a known problem without resolution. Shame as in other aspects it appears to do a good job.

My company is starting a major greenfield development project using DevExpress WPF controls. I just read this critical review of their WPF controls:
[…] DevExpress developers completely misunderstood WPF when they developed their WPF controls. I really cannot impress upon you sufficiently well just how much of a displeasure it is using their controls. I feel absolutely terrible (almost guilty) about talking about a vendor with such negativity, but they have made a serious mistake in their WPF suite, it has been a singular source of the most abject frustration for me in about a decade of developing software.
Do you agree that DevExpress does not understand the WPF paradigm and will cause our developers grief during development and maintenance? Can you suggest an alternate vendor of WPF controls? I'm looking for a vendor with WPF controls that will enhance our application while fitting well with the WPF API, binding and MVVM.
The link (above) to the critical blog post is broken. The original author has stated:
I wrote the original article, and have decided to work with DevExpress in a private capacity after speaking with them so I have regrettably decided to remove the post. Regards, Ira
Abject frustration is EXACTLY what I experienced thanks to DevExpress. I lost hours of my life attempting to simply bind a combo box. The drop-down list at best would only display my ItemsSource class name multiple times. I even posted a StackOverflow question to figure out what I could possibly be doing wrong. Finally on a whim I tried removing this one line of xaml:
devx:ThemeManager.ThemeName="DeepBlue"
Suddenly my problem went away. It was caused by the Developer Express wpf theme DeepBlue. Discovering the problem was a tremendous relief. My company will now be using Telerik WPF controls. My colleagues are quite happy with DevExpress Asp.Net controls. It is only the WPF suite we are avoiding.
I would like to clarify our opinion on usage of our controls in applications built based on the MVVM pattern. At the moment, we are working on a series of examples which should clarify how our controls can be used under different popular MVVM based frameworks (like Prism, MVVM Light and so on). There are a couple of problems in our WPF controls regarding the MVVM pattern and we are trying to eliminate them. However, generally there are no showstoppers that can prevent a developer from using our controls in a MVVM application. Hopefully, our examples, posted on the DevExpress Web Site will convince you in this.
I do not agree completely with the assertion that DevX developers missed the mark on WPF. However, I will say that it appears they may have had a steep learning curve to overcome. Lets face it, WPF is massive. To master it, even out of the box, is a daunting task. I do agree that DevEx controls will not fit into a MVVM pattern, but they do sit quite nicely in a MVP pattern. "Can you suggest an alternate vendor of WPF controls?" No, but I will suggest that you study additional patterns if you are stuck with DevEx.
I have used Syncfusion, Ingragistics, Telerik as well as various smaller libraries and DevExpress is my platform of choice. I find them to be not only super supportive of WPF and MVVM but their tech support has been phenomenal. I actually was mid project in a multi-million dollar project using Syncfusion WPF and found so many bugs in the library that my customer was close to pulling the plug. I switched mid stream to DevEx and they save my bacon. Their controls always seem the most up to date and incorporating the latest trends. I wish they did more Xamarin stuff and some of the other things that Syncfusion does but I would rather have less stuff that actually works than a wide array of stuff that doesn't.
Which library to use for WPF?
Infragistics
ComponentOne
SyncFusions
ActiProSoftware
Telerik
#Reed - None of the Syncfusion WPF controls were ported from Windows Forms. With the grid control, most vendors use a simple ItemsControl based architecture. We have a much more elaborate infrastructure for highly optimized cell oriented rendering. This was implemented to achieve performance as close to Windows Forms performance as possible. The effort on our end to deliver this solution when contrasted with a pure ItemsControl based approach was at least 5x. We have a lot of customers using our Windows Forms controls in real-time scenarios and we wanted to give them the ability to move over to WPF without losing on the performance front. Our key controls offer excellent rendering performance even with millions of data points in direct contrast to solutions that are based on a simple ItemsControl based approach. Our controls often have a steeper adoption curve than others but in the long term we do believe that they are easier to maintain and update. Just my two cents:) Also, we are really keen to work with you on any issues that you are running into. Please let us know. My email is danielj(at)syncfusion.com.
#Tom - If you can send us feedback on the gauge we would greatly appreciate it. We are always looking for ways to improve and your feedback will be really useful.
Ultimately it depends on what you need. I think Syncfusion offers the widest and most actively deployed control suite on the WPF front. Disclaimer - I work for Syncfusion.
I work for a large firm which has long-term license agreement with Syncfusion so I had to use their products for years in pain.
I agree with Reed for Syncfusion's model. They converted their Winforms model (which has major bugs) to look it like WPF, I believe the whole suite is nothing to do with WPF, most of their controls cannot be controlled in XAML, you need to use code behind in order to style even simple things.
They are actually improving this to look more like WPF however with Syncfusion one issue is when you upgrade to a new version, it always breaks previous version based code. It is their marketing strategy and you spend weeks to figure out the new system.
One other issue with Syncfusion is they have quite poor documentation, their support is very weak, so you need to discover things on your own.
I used Telerik WPF in one project which is a much better choice, the performance is much better and the model is really easy to maintain.
We just started to buy DevExpress due to the pain of Syncfusion over years and I believe this is quite good WPF product. It is easy to use, they have really good support and nice documentation. The controls look very professional. First time I feel like I am using actual commercial .NET toolset.
*I do not work for DevExpress or Telerik.
They all have advantages and disadvantages.
Personally, I've found Telerik and Infragistics seemed more like they were designed specifically with WPF in mind.
Syncfusion's offering is more of a port of their Windows Forms product, so the design is more like they're other product lines.
That being said, each product you listed is good - and each have their own feature set. There is no substitute for trying a demo and seeing how you like working with the products in question.
I'm a fan of Component One, mainly based on personal taste.
ActiProSoftware have some good controls, but I find that they don't expose enough properties to make it easy to style and customize, though you can get around this with implicit styles.
Xceed have my favourite Grid control, lots of cool features and easy to work with.
I don't particularly like Telerik and I've never tried SyncFusion.
I would love to try Infragistics as that is one that I haven't tried, but have been really impressed with the demos. Does anyone have any comments on the architecture of Infragistics?
Like Reed said, they all have their advantages and disadvantages, but from my experiences I would recommend Component One.
HTH
None of the above, just use WPF Toolkit for DataGrid and VisualStateManager. It is not that hard to style the controls in WPF/Blend, plus it makes YOU more proficient and your code leaner.
P.S. Though, you might still use third-party reporting, since there no built in support for reporting in WPF.
If you are looking for a WPF Control Library there is the WpfDynamicUI Library.
It is an open source control building the user interface for the DataContext you provide.
It supports Charting, DataGrid, Map, Filtering, Paging, Nesting views and more...
Can be an alternative for building Line Of Business application.
PS: I am the coordinator of WpfDynamicUI
Well we are considering to move from WinForms to WPF, what pitfalls does WPF have? And we got component one's flexgrid is there any wpf grid that has the same functions? one nice thing with it is that you can implement your own draw method for the cells... It can merge cells print and save to many file formats..
In general, WPF development is very different from WinForms. You should expect it will take some time to learn the new technology (or you might even need to hire new developers =)).
WPF approach is in many ways better than WinForms' one: check out styles and triggers, data binding, control templating, eventing model.
I would recommend you to start exploring it, but wait for the WPF 4 (and the boring MSDN page) to start the actual migration, because it is going to be even better and close some of the very annoying gaps.
First of all, WPF works pretty different from Windows Forms and likely requires a different approach on how to structure and design the application. At least it works way better if you do it the way it was conceived.
As for single Windows Forms controls, this shouldn't be a problem. There is a WindowsFormsHost which enables you to include Windows Forms controls in WPF.
The change from winforms to WPF is not a change I'd reccommend unless you have specific requirements which WPF fulfills - WPF is not intended to be a replacement, simply an alternative which is more suited towards graphically rich applications.
If you do have a specific requirement then you also might want to consider embedding WPF controls into winforms applications, rather than converting your entire application.
The learning curve is slow to get going, but once you get the idea it all starts to make sense. We have "Pro WPF in C# 2008" book floating round the office and its been a great help. Of course most things get googled to find an answer, but to find out why something is done the way it is this book was a great hope - to me anyway.
There are some annoying features but its still WPF is still quite new. Like most things, if you come across a problem someone has likely come across it before and there is an answer out there!!

Take a look here for a datagrid: http://wpf.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=29117
The main hurdle with WPF is simply the huge amount of new stuff to learn (if you wish to use it properly). I'd think twice if you're on a tight schedule, but it might be worth it if you have 6 months to spare...
Speaking from just my experience, moving from Windows Forms to WPF took some re-learning. A few months into the transition most changes made total sense. WPF removes much of the frustration associated with using Windows Forms. It allows for a truly rich UI development experience especially when working in tandem with designers. I strongly recommend WPF Illustrated by Daniel Solis as a learning aid.
With reference to the grid, Syncfusion offers a WPF grid control that implements the features you have asked for. It implements true virtual mode with cell level customization, printing and export to multiple formats including Excel. Disclaimer - I work for Syncfusion.
i've been learning wpf for about a week now..
and i have a basic question:
From a business view and development view (out of your experience).. what can and what cant be done with wpf(capabilities) ..
please try to be illustrative..
examples of undesired answers:
"Fully functioning stand alone applications with alot of animation and Glittering images"
A second question:
if i build a XBAP UI for my application, can i make the UI "not show" in a browser!
if u r going to answer from tutorials/websites/books.. please dont copy paste them directly, try to write it in your own words...
You can host anything built to the Win32 GDI/USER API (WinForms, ActiveX controls) inside a WPF application, so even if you hit some limitation with an app that is mostly WPF, you can always host some old controls inside it.
And since 3.5 SP1 you can even host animated DirectX graphics pretty seamlessly as well (although WPF's 3D support provides its own much simpler ways of achieving the most commonly done things).
As for comparison, the major advantage of WPF over WinForms is the way it keeps closely to its own component-based model, so a very large proportion of controls are able to act as containers for other controls. Want to put a combo box in a menu item? Not sure why you would, but you can. More usefully, you can put a button in a list box (or tree view). These kinds of thing are not possible unless you implement every standard control from the ground up (which is what WPF does).
The disadvantages are probably temporary: it can be a little unstable on some machines (the rendering code seems vunerable to display driver incompatibility) but this gets better with each service pack. Also the text rendering has been heavily criticised - it goes a bit further with ClearType anti-aliasing than Windows normally does, so some people complain that it looks blurry.
(The reason these are likely to be temporary issues is that Microsoft's Visual Studio 2010 is adopting WPF. So they are now "eating their own dogfood".)
You can pretty much do anything in WPF that you'd need from a GUI app. But that's not the real benefit, IMHO.
One of the real benefits of WPF is development speed and simplicity, once you get past the learning curve (and there is a learning curve!)
The other major benefit, and probably the biggest one, is that it allows designers to work on the presentation, do lots of interactive things, all using a designer-friendly (friendlier, anyway) tool and not having to submit requests to the coders. Just by changing the .xaml, a designer can make an application look almost completely different, and add all kinds of behaviors (panels disappearing, expanding, all kinds of neat stuff). Without changing a line of code.
You can in theory do anything in WPF what you want. Compare it with a WinForms application. Is there anything that you can't build with that? Not really. The same goes for WPF. It's just that WPF is better suited for some things, like animations, video, graphics, etcetera. As it is xaml based, it is also better suited for databinding against XML for example.
See also this related question.
As for your second question, I'm not sure what you mean by that. Do you mean if you can show websites using WPF? Yes of course, just like WinForms.
Oh, in WPF some things are still not implemented. DataGridViews as popular example are only in the codeplex preview. YOu have alot of things like theExpander which work in a differnet way, and you can have a lot of problems with autosized content.
I am currently using Telerik's carousel control, but it is lacking many features and is buggy. Is there a good control out there that looks the the coverflow control in itunes?
WPF Cover Flow Tutorial
Source Code: Part 7, Download
Author's rebuttal to claim of memory leak (it doesn't): Part 8
In Action: Videos
Contains a detailed walkthrough for building a coverflow control, including features such as reflection. I compiled and tried it out and pointed it to a directory containing hundreds of smallish images (you'll need to edit TestWindow.xaml.cs to point to a directory containing jpg's) and I was impressed with the performance and smoothness of the animation.
I noticed that using very large images degrades the performance though, so I'd recommend using images that are just the size needed for display. For example, when pointed to my desktop background images directory, there was nearly a one-second delay after pressing the arrow key and the item going through the transition (although the animation itself was still fluid, it took a moment to begin).
This is the best one that I found, for what I was looking for - namely, non-commercial, reflections, and smooth animation. I did look at the other ones currently mentioned in the other answers though, here are some comments on them (in no particular order):
FluidKit's ElementFlow
Open source, I used the latest source code, but did not try out any patches
Animation was smooth
Transition didn't feel very refined, the pictures clip each other in an odd way
Didn't seem geared for showing a handful of element's on the screen at once, it tries to show everything, and from some of the discussion comments, apparently isn't virtualized
After adding some images to the demo through the provided button, a large portion of them couldn't seem to get selected
Doesn't have reflections
Mindscape CoverFlow
Commercial
Animation was smooth
Doesn't "popup" selected item, feels very 2D
Has reflections
DevExpress Carousel
Commercial
No online demo and I didn't try to obtain the trial, looks polished though
Telerik Carousel
Commercial
Animation was smooth
The transition wasn't as pleasing to me, the new picture passed through the old one
Doesn't have reflections
Xceed Cardflow 3D
Commercial (professional edition only)
Animation was smooth, if you went quickly it would show blank cards speeding by and then fade in the actual data on the cards when you slowed down
Supports flipping the selected item, like in iTunes
Has reflections
ElementFlow control is inside the codeplex project called FluidKit - can be downloaded from here
For more details about the control - ElementFlow control at Pavan's blog
Mindscape now provide a commercial WPF Coverflow control as part of their WPF Elements control pack that might be useful also.

http://www.devexpress.com/Products/NET/Controls/WPF/Carousel/dependency_properties.xml
Both of these are FAR more versatile than your average cover flow clone (though they can easily just do that too if you want). I'd recommend Telerik well above DevExpress as WPF is still a relatively immature technology and DevExpress are very poor at keeping up with the tech game (they only JUST released a VS2010-supporting version of their DXperience suite despite promising it "just around the corner" since the start of January, while Telerik, ComponentOne etc all keep up with current tech. Not good enough for enterprise).
