  How I can determine when a Detail Row is being loaded/made visible in C1FlexGrid for WPF v4.5.2. I can’t find any event similar to C1DataGrid’s LoadedRowDetailsPresenter event. I can see how to do this in the .NET 5/6 version of FlexGrid, but not the 4.5.2 version.

  Hi,
  
  Please note, there is no direct way in C1FlexGrid to know about the details row loading . However, you can use a specific workaround based on the requirement using PreviewMouseLeftButtonUp event as shown below.

  private void Grid_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
     {
         Point p = e.GetPosition(grid);
         HitTestInfo hittest = grid.HitTest(p);
         if (hittest.CellType == CellType.RowHeader && grid.Rows[hittest.Row + 1].IsVisible == true)
         {
             var panel = hittest.Panel.GetCellRect(hittest.CellRange);
             var ele = grid.InputHitTest(new Point() { X = panel.Width + 10, Y = grid.ColumnHeaders.ActualHeight + panel.Bottom + 10 });
             if (ele is TextBlock && (ele as TextBlock).Parent is Grid)
             {
                 Grid sp = (ele as TextBlock).Parent as Grid;
                 MessageBox.Show("Main Row Index = " + hittest.Row + "\n Detail Row Index = " + (hittest.Row + 1) + "\n\n" + (sp.Children[0] as TextBlock).Text + (sp.Children[1] as TextBlock).Text + "\n" + (sp.Children[2] as TextBlock).Text + (sp.Children[3] as TextBlock).Text);
             }
         }
     }
  
  

  Note: implementation is specific to use case there is no guaranteed to work for all time.
