Styling individual items in tree

[Anders]

Hi telerik,

The users of our MVVM application would like items to be 'marked' in various ways; a combination of italics and bold is desired.

Currently, we style the items as shown below, reacting to changes in IsSelected.

The other thing we would like to react on is whether the treeitem's editor (in another window) is given focus, but of course there is no relevant RadTreeViewItem property to bind to - how would you go about this? Can we intercept the styling somehow and for each item - in code-as-opposed-to-markup - apply the style as we see fit?

Thanks for any input,

Anders, Denmark

Hi Anders,

Basically at any time you can set the RadTreeViewItem.Style or the RadTreeView.ItemContainerStyle properties. And when the window for editing the item is opened you can apply a custom style to the RadTreeViewItem that is edited. Also, the RadTreeView control exposes also an ItemContainerStyleSelector property that gives you the ability to change the style for the RadTreeViewItems based on custom logic like a data property value, for example.

I hope this info will help you implement your scenario. However, since I am not sure if I properly understand it, if I am missing something, please send us a sample code/solution demonstrating your requirements and scenario. Then we will be able to look further into it and find other approaches.

All the best,
