Hi Alexander,
Thank you for your interest in Syncfusion products.
To loop through the GridGroupingControl columns make use of visiblecolumndescriptor
collection and check the condition whether columns are empty in the loop.
Please refer the below code:
foreach (GridVisibleColumnDescriptor visibleColumnDescriptor
in gridGroupingControl1.TableDescriptor.VisibleColumns)
{
//condition for empty columns
}
To remove column from the visible columns list kindly make
use of below code:
this.gridGroupingControl1.TableDescriptor.VisibleColumns.Remove("Col1");
Regards,
Praveena.
