DataGridView1.Columns.Add(buttonColumn)

Dim buttonColumn As New DataGridViewButtonColumn
buttonColumn.Name = "Button"
DataGridView1.Columns.Add(buttonColumn)

Thank you. It works. but how to add click event to the button to monitor the changes to a special cell in the certain row.

In my opinion, the best way to do this is using the System.Windows. Forms.DataGridV iewCellEventArg s. It is saved in 'e' as shown in the line of code beneath:

Private Sub DataGridView1_CellClick(ByVal sender As Object, [B]ByVal e As System.Windows.Forms.DataGridViewCellEventArgs[/B]) Handles DataGridView1.CellClick

You make sure that you know the name of the column the button is in and then you query the 'e' for the columnindex. After that, you track which row is clicked by using 'e' for the rowindex. Something like this:

Dim gr As New DataGridView
gr = sender
  Select Case e.ColumnIndex
    Case Is > -1
      Select Case gr.Columns(e.ColumnIndex).Name
        Case "Button"
          return gr.Rows(e.RowIndex).......etc.

[/CODE]

Cool,everything works.
