Style problem

[Daniel]

Hi!

I have some problem with applying a style on a custom control derived from RadTreeListView.
This is the base style that works correctly on original RadTreeListView:

<Style TargetType="{x:Type telerik:RadTreeListView}" x:Key="IprRadTreeListViewStyle" BasedOn="{StaticResource IPRBaseStyle}">
        <Setter Property="ValidatesOnDataErrors" Value="None"/>
        <Setter Property="telerik:StyleManager.Theme" Value="Summer"/>
</Style>

I create another style based on the previous style:

<Style TargetType="{x:Type controls:IPRRadTreeListView}" BasedOn="{StaticResource IprRadTreeListViewStyle}">
</Style>

The CS code of my custom control:

class IPRRadTreeListView : RadTreeListView
    {
        static IPRRadTreeListView()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(IPRRadTreeListView), new FrameworkPropertyMetadata(typeof(RadTreeListView)));
        }

        public IPRRadTreeListView() : base()
        {
           ...
        }

        ...
    }

If I run the application then my IPRRadTreeListView control doesn't become visible. I tried to apply the style explicitly ( Style = {StaticResource IprRadTreeListViewStyle} ) on my control but I had the same result: IPRRadTreeListView wasn't visible.

This scenario works correctly for IPRRadGridView (derived from RadGridView).

Could anbody help me, please?

Hi Daniel,

There appears to be such an issue with RadTreeListView. I have logged it in our bug tracking system. It will be fixed in some future release of RadControls. Thank you.
