Question: I've just logged this with Microsoft Connect, but I'm wondering whether anyone else has come across it and found a fix. Google's not showing much...

Simple repro:

* Application has a WPF textbox with MaxLength set
* Use the TabletPC input panel to write more text than is allowed
* Press "insert" on the TabletPC panel and the application crashes

Beyond changing the behaviour of my application to not use MaxLength, does anyone know of a solution?

(I'll post here if Microsoft come back with any advice.)

**EDIT:** Should have specified I'm running .NET 3.5 and Windows 7.

Answer: 
Apparently this is fixed in .NET 4.0, but no plans for a 3.5 fix. The suggestion from MS was to handle the TextChanged event to provide MaxLength automatically (ew!).
I'll be honest, I've no experience with either WPF or Tablet PC interactions so I'm shooting blind here but I'll either hit the target or learn something :)

From my simplistic view point I see a number of work arounds, all involve removing the max length:

1. On submission, truncate the string in the VM if too long
2. On submission, alert user to truncation and present truncated string back to them in the textbox for editing
3. Hang an event off the textbox and truncate the string "OnChange" with a label alert adjacent to the field, like a web form error.

Anyway, I hope you get some responses from some people who know what they are talking about ;)
