I am using a RadTreeListView with MaterialDesign theme in a Windows WPF application. By default the selected cell is indicated by a grey line at the bottom of the cell. I don't want an indication for the selected cell and used the advise from forum to change the style as follows:

  <Style TargetType="telerik:GridViewCell" BasedOn="{StaticResource GridViewCellStyle}">
    <Setter Property="CurrentBorderBrush" Value="Transparent"/>
  </Style>

This works fine.

But if changing the Windows application with Alt+Tab and then back to my application with Alt+Tab the cell selection (grey underline) is displayed.

Reproducible on http://demos.telerik.com/silverlight/#TreeListView/TreeListViewDragAndDrop

Items are expanded when they match the filtering criteria.

Once I added the filterdescriptor, the tree started to expand itself
and when I put a break point in RowIsExpandedChanged event handler
the treelistviewrow's IsExpanded property is already true

Can you have a look at the attached sample application
and try to achieve the following:
1. keep the on demand load (so only loadchildren when user clicked on the arrow to expand)
2. apply filter only on the expanded nodes

The horizontal scrollbar of RadTreeListView is displayed even the setup suggest that it should not be. For example, this happens if you have a single column with its Width set to * which means that the RadGridView should span in the available space without the need of displaying a horizontal scrollbar. To recreate this the RowIndicatorVisibility property should be set to Collapsed. Additional to that there should be a hierarchy and the items should be expanded.

To work this around, you can set a fixed Width for the column. If you want this to be dynamic you can calculate the width on SizeChanged of RadTreeListView
