Recently, when we enabled UI virtualization for RadTreeView in our application, our icons for the RadTreeViewItems disappeared.
We set the icons (DefaultImageSrc) in DataTrigger setters in a style, as follows:
This is with UI for WPF v. 2015.2.0401
1) Can I get a confirmation that this bug is indeed causing our difficulty, please? Is there anything else you see that would cause it?
2) It looks like you all have declined to fix this bug in the past. Still declining? :)
3) I could recommend that the documentation for UI Virtualization with RadTreeView here be updated, please, to to include some very obvious notes, a) that enabling virtualization will disable DefaultImageSrc and ExpandedImageSrc (and any other TreeView features that don't work with virtualization?), and b) that workarounds are necessary.
