Datagrid Contextmenu Pop up

I am using the following code to pop up a menu:

if(e.RowIndex>=0&&e.ColumnIndex>=0&&e.Button==MouseButtons.Right)
{
dgSJ_Yarn.Rows[e.RowIndex].Selected=true;
Rectangler=dgSJ_Yarn.GetCellDisplayRectangle(e.ColumnIndex,e.RowIndex,true);
contextMenuYarn.Show(dgSJ_Yarn,r.Left+e.X,r.Top+e.Y);
}

There are 2 rows in the grid ... the 1st row/column his highlighted when the grid opens for the first time.
When i right click on the 2nd row the full row is selected but the 1st row/column of is still selected as well.

How can i configure the grid so that is only the 2nd row is selected?

I tried changing the selectionmode to fulllrowselect but the rowheader stays on the 1st row.

thx

You can set the DataGridView.MultiSelect to false. This will prevent the user from selecting multiple rows as well as achieving the desired effect with your code.

Alternatively, de-select currently selected rows by calling DataGridView.ClearSelection method before you set Selected = true.
