Is that code is working on DataGridView Control ? I've been tried to use that code in DataGridView but no luck ...

Thanks :-)

>Try something like (if you want to force numeric instead, change to ! to force numeric or use char.IsNumeric):

>public class NumbersOnlyTextBox : TextBox
>{
>  public NumbersOnlyTextBox()
>  {
>    KeyPress += new KeyPressEventHandler( HandleKeyPress );
>  }
>
>  private void HandleKeyPress( object sender, KeyPressEventArgs e )
>  {
>    if ( ( char.IsDigit( e.KeyChar ) || char.IsControl( e.KeyChar ) ) )
>      e.Handled = true;
>  }
>}
