   }

// Check if the first row is selected.
private void button8_Click(object sender, EventArgs e)
{         
   if(myDataGrid.IsSelected(0))
   {
      MessageBox.Show("Row selected",
         "Message",   MessageBoxButtons.OK,

         MessageBoxIcon.Exclamation);
   }         
}
// Deselect the first row.
private void button11_Click(object sender, EventArgs e)
{
   myDataGrid.UnSelect(0);
}

' Check if the first row is selected.
Private Sub button8_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button8.Click
    If myDataGrid.IsSelected(0) Then
        MessageBox.Show("Row selected", "Message", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
    Else
        MessageBox.Show("Row not selected", "Message", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
    End If
End Sub

' Deselect the first row.
Private Sub button11_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button11.Click
    myDataGrid.UnSelect(0)
End Sub
