Sizing for multiheader rows

Hello I am trying to use multiheader rows with GridControl. For that I froze the two first lines (with GridControl.Rows.SetFrozenCount) and "merged" the columns in the first line (by using GridControl.CoveredRanges). It works fine but I would like that the user resizes the columns on the second header row and not the first one. How can I do that? Thank you! Thierry

Hi Thierry, This can be acheived by setting the GridResizeCellsBehavior flags and by using the ResizingColumns event handler. Here is a code snippet. // In Form1_Load event this.gridControl1.ResizeColsBehavior = (((Syncfusion.Windows.Forms.Grid.GridResizeCellsBehavior.ResizeSingle | Syncfusion.Windows.Forms.Grid.GridResizeCellsBehavior.InsideGrid) | Syncfusion.Windows.Forms.Grid.GridResizeCellsBehavior.OutlineHeaders) | Syncfusion.Windows.Forms.Grid.GridResizeCellsBehavior.OutlineBounds); private void gridControl1_ResizingColumns(object sender, Syncfusion.Windows.Forms.Grid.GridResizingColumnsEventArgs e) { if (e.Reason == GridResizeCellsReason.HitTest) { GridRangeInfo range = gridControl1.PointToRangeInfo(e.Point); if (range.IsEmpty || range.Top != 1) e.Cancel = true; } } Here is a project sample, Let us know if you need further assistance, Regards, Madhan.
