Hi,

I  want to auto size the every column by its content text automatically.because when the radtreelistview have a long content the column take all time this size even if I loaded with other data.

column.Width = GridViewLength.SizeToCells;
but it dosen't work.

Hello Fatima,

 In order to auto size the TreeListView's columns you can set it's property ColumnWidth="Auto". Please see the code below:

<telerik:RadTreeListView ColumnWidth="Auto"   Name="radTreeListView1">
         <telerik:RadTreeListView.ChildTableDefinitions>
                 <telerik:TreeListViewTableDefinition  ItemsSource="{Binding Items}" />
         </telerik:RadTreeListView.ChildTableDefinitions>
 </telerik:RadTreeListView>

Hi,

thank you for you answer .

but the solution that i found and works :

     Tlv.Columns.OfType<Telerik.Windows.Controls.GridViewColumn>().ToList().ForEach(c => c.Width = 0);
     Tlv.UpdateLayout();
     Tlv.Columns.OfType<Telerik.Windows.Controls.GridViewColumn>().ToList().ForEach(c => c.Width = new GridViewLength(1, GridViewLengthUnitType.Auto));
