adding programatically FilteredTextBoxExtender


 Hello, I have a problem with adding programatically FilteredTextBoxExtender (i put the code below).

The problem is that nothing is outputed when page is renedered although TextBox and FilteredTextBoxExtender are added to container (table cell controls property in my case).


TextBox tbDictionaryEntryTextBox = new TextBox();
tbDictionaryEntryTextBox.ID = "tbDictionaryEntry_" + controlNameSuffix;
tbDictionaryEntryTextBox.Width = Unit.Pixel(controlWidth);
if (isNumeric) {
      ftei = new FilteredTextBoxExtender();
      ftei.ID = "fteDictionaryEntry_" + controlNameSuffix;
      ftei.TargetControlID = tbDictionaryEntryTextBox.ID;
      ftei.FilterType = FilterTypes.Numbers;
      ftei.Enabled = true;         
Best Regards,


Delete key not working with Firefox and FilteredTextBoxExtender

I'm using FilteredTextBoxExtenders for my textboxes with filtertype set to numeric. Everything works fine in IE but in Firefox, the delete key and arrow keys will not work in the textbox.  Backspace key does work.  This is a problem if the user needs to change the contents of the textbox after somethng has been entered.  Is this a bug, is there a fix?
