How can I change the backColor of the Captions(GroupedRowHeaders) of the GridGroupingControl after grouping when I click on them with SHIFT key - to select several captions.

Hello,

How can I change the color of the Captions(GroupedRowHeaders) of the GridGroupingControl after grouping when I click on them with SHIFT key - to select several captions.
And this captions is not expanded and the event TableControlCellClick raises only for first Caption and for the last caption from selected group when I click on it with SHIFT key!!!

So if we have such captions

A1
A2
A3
A4
A5

and I select (click) A1 and with SHIFT key click(select) A4 - so the event is raising TableControlCellClick only for A1 and A4 caption clicks!!!

The event SelectedRecordsChanged cant help me!!!

I know how to chage backColor - I have a handler:
private void clientGridControl_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
//if (clientGridControl.TableControl != null)
//{
// if (e.TableCellIdentity.RowIndex == 4 && e.TableCellIdentity.ColIndex == 2)
// {
// //GridTableCellStyleInfo style = clientGridControl.TableControl.Model[4, 2];
// //Element el = style.TableCellIdentity.DisplayElement;

// if (e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Caption)
// {
// e.Style.Themed = false;
// e.Style.BackColor = Color.Yellow;
// }
// }
//}

bool flagChanged = false;
if (e.TableCellIdentity != null &&
e.TableCellIdentity.DisplayElement != null &&
e.TableCellIdentity.DisplayElement.ParentGroup != null &&
e.TableCellIdentity.DisplayElement.ParentGroup.Category != null)
{
if (e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Caption &&
e.Style.Text != "")
{
if (flagChanged == false)
{
if (_dicElementGridCaptions_Clicked.Count > 0)
{
//if (_dicElementGridCaptions_Clicked.ContainsValue(e.TableCellIdentity.DisplayElement) == true)
if (_dicElementGridCaptions_Clicked.ContainsKey(e.TableCellIdentity.DisplayElement.ParentGroup.Category.ToString()) == true)
{
e.Style.Themed = false;
e.Style.BackColor = Color.SkyBlue;
flagChanged = true;
}
else
{
e.Style.BackColor = System.Drawing.SystemColors.Control;
}
}
else
{
e.Style.BackColor = System.Drawing.SystemColors.Control;
}
}
}
}
}
Best regards, Alexander.

Hi Alexander,

Try setting the TableOptions.AllowSelection property to GridSelectionFlags.Any and set the add the selected range using TableModel.Selections.Add method. Please refer to the attached sample for implementation and let us know if you are looking something different.

this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.None;
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Any;

//Add the Selection from 4th row to 8th row in a grid
this.gridGroupingControl1.TableModel.Selections.Add(GridRangeInfo.Rows(4,8));
