I want to show a list of items from a database. The number of items could be anything between 10 to a 1000; well not a 1000 but at least more than 20 or so cards that have some texual details and a small thumbnail image. I want them to be displayed as similar to the list of folders in windows explorer when the view slider is in "Large Icons" position. I think I can accomplish that using this example while using a traditional listbox. But that makes the listbox scroll motion very boring.
Using a pathlistbox, I have a little more control over the list motion path. However, in all the online samples I have seen, there are only a few items that can be shown using a pathlistbox. I don't suppose I can show more than 20 cards in a circle or any other shape with all the aforementioned details. It will be really hard to scroll through them. Is the pathlistbox only for gimmicks or can I really use it to show many more than just a handful of items? Any tips or pitfalls in the Pathlistbox that I should be aware of before I begin using it or am I better off using just the simple listbox?
Would like to have your thoughts on the same. Thanks for your time...

My goal is to have a diagram which look like this
Each arrow should be a one dimensional chart, where point are displayed (colors and point size depends on some values)
I'm building my own chart system because I spent a few hours looking for one which allow to custom markers (size and colors, and maybe even shape) but I couldn't find one.
Actually the only one I found is dynamic data display 2.0 which is only proposed in Silverlight.
My biggest problem is the two curving chart I have to do at the top of the diagram.
I tried to use PathListBox control, but because it's a listBox, I couldn't display items at fixed X position (like using a chart).
I'm not asking for a full perfect solution, but can someone give me advices, or clues ?
How would you manage to do something like that ?
It should only be a XAML work here, because all the data are already ready in a ListCollectionView (i'm using MVVM).
Thank you !
First time working on a GUI project.. and first time doing work on Windows so apologies in advance if this is a really noob question.
I'm taking baby steps into windows programming starting with vb.net WPF. Working in Visual Studio Express 2012.
I'm trying to work out how I can scale all the elements in a window with the window itself.
So for example, I'd create a window, say 1280x720, and place some images in the window. Say one at the top and one in the corner. (this is a basic media based application)
When I resize that window, I want the entire window to scale with it, so image 1 & 2 will get larger if the window gets larger, however this has to happen proportionally so that if I make the window a lot bigger in one direction one image can't overlap the other. Imagine the window is an image and I'm trying to resize it. (The overlap thing is the closest I've gotten to getting this working in my current attempts).
The layout in produciton will be more complex, comprising of mediaelements (video), images, text etc and all must scale accordingly.
This isn't something the user interacts with and so there are no form elements etc, and so I don't need form fields etc to stay the same size throughout scaling. I just need everything to scale like I'm scaling a picture. If for example I displayed this 1280x720 (16:9) layout on a 1920x1080 screen, maximised it should look identical only larger.
Hoping someone can point me in the right direction with this.
What I've tried so far- the few articles I did find on google relating to this (I may well be searching the wrong things) lead me to put all the elements in a viewbox, this lead to the overlap I mentioned earlier.
Ideas ?
I think you could use ViewBox container. The basic idea is as follows: ViewBox scales its content just as if it was an image scaled. This seems to be the closest result to what you've described in your question. Just put a Grid with absolutely-sized columns and rows into the ViewBox and set its Stretch to be Uniform:
<Viewbox Stretch="Uniform">
<Grid>
<..>Your controls, MediaElements, etc
<Grid>
</Viewbox>
You could also combine it (or entirely replace) with (e.g.) Grid Container : it gives you an ability to specify cell width and size usign star-syntax which is similair to html's percent syntax.
Another way is to use the DockPanel.
All-in-all there are plenty ways to achieve something similair and the way to go largely depends on the nuances of your particulair requirements.
Have a look at This tutorial to see a good overview of WPF containers and how to use them.
Being new to silverlight I'm struggling to 'get going' with the following.
Basically I wish to create some form of grid like control (custom or user?).
The idea is similar to that of a planner. Along the top are times (set intervals). Downwards are subjects. Then over the grid like background rectangles (or something) indicate when the subject is planned for.
The actual design of the above is not the issue. i.e. a grid with ractangles overlaid. But my issue is I wish this grid to be scrolled up and down (with bounds fixing the top and bottom when the subject lines start and end). And also the grid to be scrolled left and right (with bounds fixing how far left and right it can scroll, current time & 3 days into future).
Based on the above needs, I don't wish to create a control which is very large, and just dragged into view (unless this is the only way?) but instead show the grid at a current time and when dragged dynamically load the next few hours worth of content, possibly with a few hours buffer.
The appearance I am seeking is it looking like it is one massive control, but truely its not, its dynamic.
Does this make sense? Am I worrying about nothing? Should I create a massive grid well into the future and then just handle the load of data dynamically over the top? Its just my concern if I want a grid 3 month into the future this would be massive and a waste of memory.
I'm struggling to find examples on the net, but feel this maybe to do with me not knowing what to search for. This isn't about getting a detailed answer and someone doing it for me, but instead about guidance pointing me in the right direction.
Many thanks
About the up-down scroll: you can simply put a grid containing your data in a ScrollViewer control - this will handle all the scrolling for you. Another solution would be using a listbox control - this is better if you use MVVM. You can bind it to a data source and set as data template a custom control.
For the left-right scroll. I'm thinking you could use gestures for this. Like - catch left-to-right and right-to-left flicks and change the data in your grid / listbox according to the gesture's direction. You could also place two buttons at the top of the grid to handle scrolling from one day to the other (just like in the calendar controls: gestures + buttons).
What is the best way to manage a very large amount of images (10,000+) in WPF? This is for a 2d tile map editor similar to this : http://www.mapeditor.org/ .
At the moment i have a canvas with all tiles as an image and a list box which contains the different images to choose from. Each tile is added to the canvas as children and then stored in a list for later access. You paint into the canvas by setting the Source property of a tile to the one selected in the listbox. It works well with around 50x50 tile maps but anything above that causes loading delays, in general slow application.
Any suggestions on this? Would QT maybe be more suited instead of wpf?
Thanks in advance
Check out Implementing virtualized panel series of articles.
Virtualized panels are efficient, because:
Only the displayed elements (and a few extra around the borders to enable smooth scrolling) are in the memory (and rendered).
Elements are reused, instead of being repeatedly created and discarded - an old cell is simply filled with new content (supplied with new DataContext) and used in new location.
You might also try to use WPF's DataGrid for this, it supports virtualization out of the box and is essentially what are you trying to do.
WPF is certainly able to do this, if implemented properly (if you can do that in JavaScript, you can certainly do it in WPF as well).
NET and learning WPF now. I want to create a tool for Pomodoro technique to learn WPF. This is the lay out in my mind.
List of tasks
Status for the task. One tomato for every 25 mins. This is list of interactive images/buttons, in which users can take some actions like add, remove tomato.
What I am looking for is tips for laying this controls out and any words of wisdom :)
what i would do is define what pieces of the UI need to be dynamic and what needs to be fixed. looks like from the screenshot, the top is probably fixed and the Task1... and the apples will be dynamic. So i would probably put everything in a grid and use a stackpanel with Vertical Orientation to hold all the tasks. Then each individual task would be a stackpanel with Horizontal Orientation built dynamically with it looks like a textblock to hold "Task1" and then varying amounts of images or whatever control you will be using for the apples and pencils and stuff like that.
