Answer 1

Try this code. Its almost the same as the most votes answer, but I edited KeypressEvent codes to make it simple and you can use this even you have to enter decimal numbers. Enjoy. :)

Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing

    If DataGridView1.CurrentCell.ColumnIndex = 2 Then

        AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress

    End If

End Sub

Private Sub TextBox_keyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)

     If (Not Char.IsControl(e.KeyChar) _
                AndAlso (Not Char.IsDigit(e.KeyChar) _
                AndAlso (e.KeyChar <> Microsoft.VisualBasic.ChrW(46)))) Then
        e.Handled = True
    End If

End Sub
