Hi Guys:
Fairly straightforward question. I'm using assembly 10.3 and wanting to add some group columns. Using both Blend 4 and VS2010 with the following code, I recieve the error message that follows the code snippet. It has to do with the way the layour and measuring routines work , however don't know what is causing the issue. Please advise.
Thanks
Steve

Hi,
I have no idea. You didn't include your HeaderStyle so i don't know what you're doing in it.
If you can attach your Style, then I can take a look at it and see what's going on.
-SteveZ
yes when i removed the header style it working, why it is not working when i set the header style, what i need to include in the header styel to make it work
I took your exact xaml, and tried it out, and it worked fine. Although i don't have your ItemsSource. Also, i had to remove the HeaderStyle that you set, b/c its not included.
Perhaps there is an issue with your headerStyle? What did you modify in it?
