    Hi,

    I am currently evaluating the radgridview in UNBOUND mode.

    I have used .Relations.AddSelfReference which works in my scenario very well

    My question is, is it possible to make the indent smaller for the sub rows

    + My Top Row
            My Top Rows Relation #1
            My Top rows Relation #2

    I would like to make this indent smaller

    + My Top Row
        My Top Rows Relation #1
        My Top rows Relation #2

    Thanks

    Hello Simon,

    Thank you for writing

    Here is an example demonstrating how you can reduce the indent space - by setting negative Margin of the CellElement:
    void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
           {
               GridDataCellElement dataCell = e.CellElement as GridDataCellElement;
     
               if (dataCell.ColumnInfo.Name == "Name")
               {
                   GridViewDataRowInfo dataRow = dataCell.RowInfo as GridViewDataRowInfo;
                   if (dataRow != null)
                   {
                       if (dataRow.ChildRows.Count == 0)
                       {
                           e.CellElement.Margin = new Padding(-20, 0, 0, 0);
                       }
                   }
               }
               else
               {
                   dataCell.ResetValue(LightVisualElement.MarginProperty, Telerik.WinControls.ValueResetFlags.Local);
               }
           }

    Attached to this post you can find a sample project demonstrating this approach. 

    I hope that you find this information useful.
