  Hello, I would like to show in every Group Rows a texbox and fire an event on TextChanged. Is it possible to do it while keeping the existing behavior (e.g. toggle feature) and style? Thanks

  Hello,

  Though, there is no direct way of adding a TextBox to GroupRow, you can still create a Custom CellFactory inheriting CellFactory, implement its CreateOutlineCellContent method and add TextBox as follows: ```
  
  void CreateOutlineCellContent(C1FlexGrid grid, Border bdr, CellRange range)
  
  {
  
  var gr = row as GroupRow;

          if (gr != null)
          {             
              // copy data from original cell
              [b]var p = bdr.Child as Panel;  [/b]    
               var g = CreateCellGrid(row, gr.Level, grid.TreeIndent, img);          
              if (p != null && p.Children.Count > 1)
              {
                  var tb = p.Children[1] as FrameworkElement;
                  p.Children.Clear();
                  tb.VerticalAlignment = VerticalAlignment.Center;
                  tb.Margin = new Thickness(4, 0, 0, 0);
                  tb.SetValue(Grid.ColumnProperty, gr.Level + 1);
                  g.Children.Add(tb);
                  [b]TextBox myTb= new TextBox();            
                  myTb.TextChanged += myTb_TextChanged;
                  myTb.Text = "Custom Text";
                  g.Children.Add(myTb);[/b]
  
                  // assign grid to cell
                  bdr.Padding = _thickness;
                  bdr.Margin = _thicknessEmpty;
                  bdr.Child = g;
              }
          }
  

  For complete implementation, you may refer [b]'ExcelBook'[/b] product sample located at [i]..\Documents\ComponentOne Samples\WPF\C1.WPF.FlexGrid\CS\ExcelBook\ExcelBook [/i] location in machine.
