Is it possible to allow users to insert text into a MaskedEdit textbox without it replacing the existing text.

So if someone wrote '1345', is it possible for them to insert '2' between the '1' and '3' without it replacing the '3' and forcing them to rewrite the full sequence again after the '1'.

Thanks

Doesn't that defeat the purpose of the masked textbox?

What kind of data does this textbox represent? You might be better off just sticking to a regular expression validator by the sounds of it.

The textbox only allows letters and numbers to be enetered and also shows some uneditable text at the front. The mask works fine and strips invalid characters when they paste into the textbox.

I would just like them to be able to paste some text in, have the invalid characters stripped, then allow them to alter the text or insert some characters after the paste.

 Hmm, I think you might be stuck on this I am afraid - the functionality just doesn't exist.

There is already a request to get this in, you can track the progress here: http://ajaxcontroltoolkit.codeplex.com/WorkItem/View.aspx?WorkItemId=15147
