Why is FilteredTextBoxExtender not working if placed in CS

[Herman T Instance]

In my code I added

                TextBox txtOverschrijding = new TextBox();
                txtOverschrijding.ID = "txtOverschrijding";
                txtOverschrijding.CssClass = "DivWidth100px";
                grdAlarmRegels.FooterRow.Cells[5].Controls.Add(txtOverschrijding);
                AjaxControlToolkit.FilteredTextBoxExtender ftbe = new AjaxControlToolkit.FilteredTextBoxExtender();
                ftbe.FilterType = AjaxControlToolkit.FilterTypes.Custom;
                ftbe.FilterMode = AjaxControlToolkit.FilterModes.ValidChars;
                ftbe.ValidChars = "1234567890.";
                ftbe.TargetControlID = "txtOverschrijding";

If I look in the gridview in the footerrow. I see the TextBox but the filtering is not working. IS there a reason or have I forgot something?

In Word you can only store 2 bytes. That is why I use Writer.

You have added the textbox txtOverschrijding to the grdAlarmRegels.FooterRow.Cells[5].Controls collection. You also need to the FilteredTextBoxExtender 'ftbe' to the same Controls collection. Hope this will help you.
