GGC Checkbox header in grouped row.

Hi, I would like to add a checkbox in the grouped header of a GGC grid. So when a user click on the checkbox, it will check/uncheck all the checkboxes in a column of that particular group. How can I do that? Many thanks.

Hi Kai, To add a checkbox in the grouped rowheader of a grouping grid, you need to change the celltype of the GroupCaptionRowHeaderCell to CheckBox and , handle the TableControlMouseDown event /QueryCellStyleInfo event to achieve the required behaviour. Please find the attachment for more details. Hashtable hash = new Hashtable(); private void gridGroupingControl1_TableControlMouseDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlMouseEventArgs e) { Point point = new Point(e.Inner.X,e.Inner.Y); Element element = e.TableControl.PointToNestedDisplayElement(point); GridTableCellStyleInfo style = e.TableControl.PointToTableCellStyle(point); bool isvalue = false; if(element.Kind == DisplayElementKind.Caption && style.TableCellIdentity.ColIndex == 0) { object obj = hash[element.ParentGroup.Category ]; if(obj != null && obj.ToString() != "" ) { bool b = (bool)style.CellValue; isvalue = !b; hash[element.ParentGroup.Category ] = !b; } else { hash[element.ParentGroup.Category ] = false; isvalue = false; } foreach( Record r in element.ParentGroup.Records ) { r.SetValue("show",isvalue); } } } private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e) { GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell; if(e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Caption && e.TableCellIdentity.ColIndex == 0 && e.TableCellIdentity.RowIndex > 2) { object obj =hash[e.TableCellIdentity.DisplayElement.ParentGroup.Category ]; if(obj != null && obj.ToString() != "") { bool b = (bool)obj; e.Style.CellValue = b; } } } Here is a sample. http://www.syncfusion.com/Support/user/uploads/CaptionCheckbox_9458c88.zip Let me know if this helps.

It does indeed work!
