I am attemting to bind to the Value property of an IntegerTextBox.
When I set the Value to a constant, it works fine. When I try to set a Binding, it throws an excepting deep down in framework code. See below for stack trace."

Hmm, I have tried this in our test application and have been unable to reproduce the problem: I have an IntegerTextBox.Value binding to an integer property successfully. If you are not using a recent nightly build, would it be possible for you to download the nightly build and try again? (http://www.mindscape.co.nz/Products/WpfElements/nightlybuilds.aspx for the trial edition, or from the store for the retail edition) I don't recall having seen or fixed a problem like this, but just in case. If you get the problem with the nightlies, could you send me a small project and instructions that reproduce the issue? You can attach zip files via the Options tab. Thanks! |
