I've got a MyGrid.Children UIElementCollection, I would like to find all the Rectangles in it that have there styles set to StyleA, and set them to StyleB.

Also, the window is not of fixed width, it ...

C# / Silverlight / WPF / Fast rendering lots of circles

I want to render a lot of circles or small graphics within either silverlight or wpf (around 1000-10000) as fast and as frequently as possible. If I have to go to DX or OGL, that's fine, but I'm wondering about doing this within either of those two frameworks first (read: it's OK if an answer is WPF-only or Silverlight-only). Also, if ...

What is the standard way of transitioning between views?

Hi, I was wondering if there is a standard way (or best-practices way) of transitioning between two views in WPF? For example, if you are looking at one particular view, and you click a button (e.g. a "Next" button) and you want to transition into the next view, what is the best-practices way of doing that? I have seen a few examples o...

Errors during value conversion

When creating a custom IValueConverter for a user-editable field, the Convert implementation is usually fairly straightforward. The ConvertBack implementation is not, since (in the absence of an explicit validation rule) it has to cope with bad user input (eg. typing "hi" in a numeric input field). If an error occurs during conversion,...

Create a View of a View in WPF

OK, so I need to create an ICollectionView from an existing ICollectionView. The idea is that I can take whatever filters/grouping/sorting has been set on the existing view and then create other views from that "base" view, in effect "layering" or aggregating my filters, etc. I need the end view to update its items "auto-magically" wh...

Is DxScene the "WPF for Delphi"? Anyone used it?

I am playing with DxScene and VxScene: http://www.ksdev.com/dxscene/index.html It looks very nice and powerful: 3d accelerated vector graphics, cross plaform, nice effects, many 2d GUI controls (vector based), good scaling, transparency, rotating (x, y, z), 3d models, etc. Even with many effects, the CPU stays very low (0%)! http://www....
