>How about putting UpdateSourceTrigger="PropertyChanged" in the binding?

That did it!

Now that this one is working, I'll convert the others in my UI window, and I'll post a new update tomorrow for you and Viv to run.

You are teaching me so many things about this stuff. And I am loving it.

Next, I want to get back to my LOB app, so I hope you not getting tired of me.


orry I can't contribute much back, but at least I can be a fan and a tester of your work.

I plant to present this app at our local user group meeting in October, so I'll be sharing all this with them. I'll show them my oringal way, and then you custom control.
