IMHO, the grid shouldn't be involved in validation of data. The data should be validated before it's bound to the grid.

Are you getting the data from a database? Is the column a numeric value column (int, decimal, float)?

VB

Private Sub DtGrid_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DtGrid.EditingControlShowing
       
       Try
           Dim TB As TextBox = DirectCast(e.Control, TextBox)
           If DtGrid.CurrentCell.ColumnIndex = Ecol_Mark.Index Then
               AddHandler TB.KeyPress, AddressOf TxtMark_KeyPress
           Else
               RemoveHandler TB.KeyPress, AddressOf TxtMark_KeyPress
               RemoveHandler TB.KeyPress, AddressOf TxtMark_KeyPress
           End If
Catch ex As Exception

End Try
End Sub

Private Sub TxtMark_KeyPress(ByVal Sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
'add your code here if e.keychar <> an integer make e.keychar = 0 
    e.KeyChar = 0
End Sub
