Visual Basic

 I added a 
DataGridViewCheckBoxColumn to My Data Grid

  Dim DesChkBox As New DataGridViewCheckBoxColumn
  DesChkBox.Name = "chbSelect"
  DesChkBox.HeaderText = "Select"
  DesChkBox.TrueValue = True
  DesChkBox.FalseValue = False
  grdView.Columns.Add(DesChkBox)
  DesChkBox.Width = 50
  grdView.ReadOnly = False
  grdView.AutoGenerateColumns = False
  grdView.RowHeadersWidth = 5


And through a procedure I want to check the Check Box programmatically.

Private Sub prcDefaultSelection()
Try
   grdView.Rows(0).Cells(3).Value = True
Catch ex As Exception
   MsgBox(Err.Description)
End Try
End Sub

The Check Box is not Checking. Please help me.
