I am working in a very crucial wpf project.This project is almost finished apart from some points.
I am showing flowdocumentreader which is loaded with dynamic images around 100.
I have one requirement to show page turn effect whenever user navigates to pages in flowdocumentreader.
I have used google and seen lots of example but no body has used flowdocumentreader.
I have also seen wpfBookControl which is not dynamic and it uses xps document.
Please help me to achieve that.
Take a look here or here.
In the WPF Shader Effects Library you have a 'negative' effect which inverts ('turns') the image.

I want to read about that effect you see on pages like Facebook or Airbnb when you open the page and the browser shows you the low fidelity design of page while the actual data loads - so you'll see grey box instead in the place where pictures of the users will be, grey rectangles instead of the text content etc. I've been searching for hours but cannot find anything useful, anyone knows the name of this UX practice?
I believe this is referred to as loading dummy content. There wasn't much info when I searched for it, but I do know that the basic principle is first load a gray background for images and dummy block font then wait for your content to render.
I have some quite complex content behind several tabs. I'd like to force the layout to happen at application startup rather than lazily as the user clicks a tab for the first time. The delay is about a second or two per tab, and it's a bit embarrassing!
Edit: I think the problem is that only the selected tab's content control is in the visual tree. Calling ApplyTemplate of the HeaderedContentControl didn't make any difference.
Does this link help you?
wpf force to build visual tree
Basically it says to use ApplyTemplate on the ItemsControl...I guess that for the tabs you should do it for each TabItem.
There's also another technique used in this site:
http://xcalibur37.wordpress.com/2012/07/12/make-your-tabcontrol-preload-in-wpf-silverlight/
Here he creates a kind of preloader for each tab. It's for silverlight but I think it can be applied to WPF.
Hope it helps out :)
I'm not too familiar with silverlight, so I'm pretty sure I am asking a basic question.
Is it possible to have a silverlight dropdown menu (like superfish, or so-called dhtml menus) in a web page that will ;
not use more space in the page than
the first level
will go over html content when we
expand it.
I guess that Silverlight has to be displayed inside a certain "canvas" like flash, so the silverlight menu has to be either :
as big as the fully expanded menu can
be -- with the possibility to display
html over it (using css?) and make
sure that the expanded items goes on
top of html ==> That seems not really
easy!
as small as the first level of menu
items -- means that silverlight has
to get out of the canvas to display
menu items ==> Is that even possible?
I know that this may sound ridiculous, but the project is to modernize the portal around sql server reporting services using silverlight in a sharepoint webpart. There's no possibility to change the setup, I just want to know if that could be achieved using silverlight. If it can't, we will fall back to superfish.
Thanks!
It is possible. Silverlight plugin should be set to windowless, so its content can overlap with html. Because Silverlight can not draw outside of its own surface you would have to make as large as biggest menu element or you could resize Silverlight container dynamically through javascript bridge.
I need a WPF control that acts like the Panorama control for Windows Phone 7, but I need it for a desktop application.
It will contain a series of panels (or Panorama Items) that the application will be able to slide through horizontally programmatically.
Also, the content inside the panels not currently displayed on the screen will need to be "lazy loaded". In other words, they should be referenced but not loaded or rendered.
Can I somehow adapt the WP7 Panorama control to do this? Or will I have to develop a custom control from scratch to behave similarly to it?
Thank you!
EDIT:
I could probably use a VirtualizingPanel to implement the lazyload behaviour.
MahApps.Metro while still not super mature does allow for the wp7 Panorama control. Demo of how to use a panorama here. I've played with it a little and while its not the most customizable thing out there it gets the job done. Pretty sweet. Also Sacha Barber (Codeproject Demigod) wrote up an article on making your own. Of which I haven't looked at yet but, the guy usually does awesome work. So I'd check that one out as well.
http://blogs.microsoft.co.il/blogs/arielbh/archive/2010/10/21/porting-windows-phone-7-s-panorama-control-to-silverlight-4.aspx gives some clues about how do to this.
It suggests using http://phone.codeplex.com/ as your base and then you can use http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=4b281bde-9b01-4890-b3d4-b3b45ca2c2e4 (Microsoft Surface Manipulations and Inertia Sample for Microsoft Silverlight) to run convert get it to respond to touch.
Seems none exist as far as I can see so far.
This blog has started an attempt at making it, so you could work from there to make your own. Be sure to also check out this page which details the creation of an individual panorama item too.
I have a NavigationWindow which hosts a series of Pages. For design reasons the Pages are fixed at 780x580 but the NavigationWindow can be set to maximize, leaving a lot of black background around my Pages.
I would like to show a fairly simple, unobtrusive animation (just some labels of various opacity/size streaming from side to side) continuously running behind all the Pages... the logical place would be the NavigationWindow so that there would be no interruption when the user navigates from page to page.
Neither Blend not Visual Studio give me access to controls when I have the NavigationPage in the designer, so my guess is that I cannot do it that way.
Anyone have a suggestion on how to do this, or a workaround that nets me the same result?
I was poking around at this alittle last night, I'll let you know if I come up with anything. Have you looked at the MSDN NavigationWindow ControlTemplate Example
