I have a radpane include a context menu. when right click over context menu, Radpane is closing and it'is problem for this component.
I used contextmenuopening event but it works before closing and it is not good idea
code is below:
<telerik:RadPaneGroup Margin="0,0,0,0" >
<telerik:RadPane Name="PaneProcess" CanUserClose="False" >
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="24" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<telerik:RadWatermarkTextBox x:Name="FilterTree" Grid.Column="0" Grid.Row="0" BorderThickness="1"
Margin="0,0,0,0"
VerticalAlignment="Top"
MinHeight="24" />
<c:TreeViewProcess x:Name="treeViewProcess" IsDragDropEnabled="True" Grid.Row="1" />
</Grid>
</telerik:RadPane>
</telerik:RadPaneGroup>
