How can I change the color of the Header of the GridGroupingControl after grouping when I click on it.

[Alexander]

Hello,
How can I change the color of the Header of the GridGroupingControl after grouping by for example column "Suppliers" when I click on this header after grouping.

I have subscribed on such event:
private void clientGridControl_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e)
{
//....
//change the color of the header after grouping and when I clicked on this header
}

Best regards, Alexander Semichev.

Hi Alexander,

This can be acheived by handling the QueryCellStyleInfo event and set the backcolor of the column header cell if the column presents in the grouped column collection. Please try it and let us know if you need any further assistance

private void grid_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if(e.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell )
{
Syncfusion.Grouping.SortColumnDescriptorCollection columns = e.TableCellIdentity.Table.TableDescriptor.GroupedColumns;
if(columns != null && columns.Contains(e.Style.Text))
{
e.Style.Themed = false;
e.Style.BackColor = Color.Blue;
}
}
}

Here is a code snippet.
