Indeed, you discovered an SL bug. One character change is not pushed by binding infrastructure to underlying object. At least two character change is required. I think this has been logged in Silverlight.net, but I am not 100% positive.

Subject: [CSLA .NET] CSLA/Silverlight Binding not responding to keypress.

Hi

I first noticed this in a CSLA Silverlight app I have been experimenting with and have just downloaded the lastest Rolodex sample and get the same behaviour.

If for instance I edit the AT&T company record by adding an extra character at the end of the company name textbox I sometimes find that the save button is not enabled when I tab off the textbox control. Even if I shift tab back or change the focused control using the mouse nothing happens until I enter another character.

On a CSLA Silverlight app that I have been experimenting with I can enter a single character into a sequence of textboxes after tabbing between each of them and get the same behaviour. I added some code and discovered that the text changed event is being invoked but none of the csla silverlight code is run.

Also if I do enter more than one character into a textbox and then click save the previous textboxes which did not cause a change in the save button lose their change.

Is this possibly a silverlight bug?

Regards
DTS
