Hi,

I am working with the CTP of the TreeListView and have a problem with the header not scrolling correctly.  I created a TreeListView with a number of columns.  When I resize the window so that the horizontal scrollbar becomes visible in the TreeListView, the scrollbar will scroll the data columns but not the headers.  This means the headers and columns don't always line up which is confusing for the users. 

Is this a known issue and if so is there a workaround?  Any suggestions would be appreciated.

Cheers,
Simon.

Hi,
Could try this workaround for now.
Add ScrollViewer around TreeList; disable Horizontal ScrolViewer in the TreeList.



<ScrollViewer x:Name="sbHeader" VerticalScrollBarVisibility="Disabled" Padding="0" HorizontalScrollBarVisibility="Auto" > 
    <telerikNavigation:RadTreeListView x:Name="TreeList" Background="White" ScrollViewer.HorizontalScrollBarVisibility="Disabled"      
                                                           IsLineEnabled="True">  
     <telerikNavigation:RadTreeListView.Columns> 
      <telerikNavigation:RadColumn MinWidth="300"   
         CellTemplate="{StaticResource ItemTemplate}" PropertyName="Name" Header="Header 1"/>  
 
       <telerikNavigation:RadColumn Header="Header 2" > 
         <telerikNavigation:RadColumn.CellTemplate> 
            <DataTemplate> 
               <TextBlock Text="{Binding Name}"/>  
            </DataTemplate>      
         </telerikNavigation:RadColumn.CellTemplate> 
      </telerikNavigation:RadColumn> 
   </telerikNavigation:RadTreeListView.Columns> 
 </telerikNavigation:RadTreeListView> 
</ScrollViewer>

I am facing a similar problem. I am unable to use the mousewheel to scroll the datacolumns. I tried the workaround of adding a ScrollViewer as am able to use the Mouse to scroll.  However, the Headers are not visible and it remains confusing for the users.

Can you please let me know if there is a fix available in later releases?

Thanks a lot

Hello,

 This thread is related to our CTP version of RadTreeListView which is discontinued. Our new RadTreeListView is based on RadGridView - you can check our latest demos here
