Hello Ryan ,
I was trying to find a good solution for this one . Setting the background directly would not do the trick as scrolling and expand /collapse operations would reset the cell.
Though it is not straightforward , there might be a solution:
You can try setting the cell background using a CellStyleSelector
The style selector itself should be something like :
ConditionalStyleSelector : StyleSelector
item, System.Windows.DependencyObject container)
//Check here if the cell matches the criteria and return a Style setting the background and targeting GridViewCell
* from within the method you can get the parent TreeListView the following way:
container.ParentOfType<RadTreeListView>(). This will give you access to the filterdescriptors so you can build your condition.
In case you find troubles implementing this , do not hesitate to open a support ticket reffering this thread and attach your project ( or a small repro) . I can implement this behaviour directly inside and send the modified version back to you .
