Resource Page Description
WPF seems to have a problem databinding to nullable value types, this page shows a couple of workarounds.

**Delete the following note before publishing **

This resource page is currently in setup mode and only available to coordinators and developers. Once you have finished setting up your resource page you can publish it to make it available to all MSDN Code Gallery visitors.

To get your Resource Page ready to publish, you should do the following:
  1. Make any changes to the details of your resource page
    1. Here you can enable or disable functions of your resource page. You might want to turn on the Issue Tracker to allow users to provide feedback on your resource, or if you have a resource that does not involve a code sample, you may want to turn off the Releases tab.
    2. Make sure your resource page description is detailed enough to let people search for your resource.
  2. Add your code sample or other resources to the resource page
    1. If you’re uploading code, go to the Releases tab and create a new release to house your code. Creating a release allows you to have the license properly displayed when people download your code, as well as provides a download count.
    2. Edit your Wiki page to attach any resources you may have that are not source code.
  3. If you want to let someone see your resource page before it is published, go to the People tab and add them to your resource page
    1. This will let you add other team members who may be contributing to your resource, or just show it off and get feedback from someone you trust.
  4. Tag your resource page with descriptive tags to make it easier for people to find your resources when browsing the gallery.
  5. Publish your resource page so it becomes visible to everyone!

Additional information on starting a new resource page is available here: Resource Page Startup Guide.

I had to write a comboxbox.selectionChanged event handler to make it work. Is this bug fixed in .net 3.5 sp1?

In Scott Guthrie's blog ( it says the WPF Data Improvements include 'Better handling and conversion support for null values in editable controls' so let's hope so!
I haven't dared install SP1 yet so I can't say conclusively!
