How to select the whole row wherever you click in WinForms GridGroupingControl?

Selection

When you set the ListBoxSelectionMode property, it selects the row on clicking on a cell and the current cell is active. This implies that, its background does not match the rest of the selected row.

To make the current cell look like the rest of the row, subscribe to the TableControlCurrentCellActivating event. In the handler, set e.Inner.ColIndex = 0. This sets the current cell on the header and not conflict with the rest of the selected row. The following code example is for changing the selection mode and CurrentCell.

//Setting ListBoxSelectionMode
this.gridGroupingControl1.TableDescriptor.TableOptions.ListBoxSelectionMode = SelectionMode.One;

//Event triggered 
this.gridGroupingControl1.TableControlCurrentCellActivating += new Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellActivatingEventHandler(this.gridGroupingControl1_TableControlCurrentCellActivating);

private void gridGroupingControl1_TableControlCurrentCellActivating(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellActivatingEventArgs e)
{
   e.Inner.ColIndex = 0;
}

'Set ListBoxSelectionMode
Me.gridGroupingControl1.TableDescriptor.TableOptions.ListBoxSelectionMode = SelectionMode.One

'Hook the event
AddHandler Me.gridGroupingControl1.TableControlCurrentCellActivating, AddressOf gridGroupingControl1_TableControlCurrentCellActivating

Private Sub gridGroupingControl1_TableControlCurrentCellActivating(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellActivatingEventArgs)
    e.Inner.ColIndex = 0
End Sub
