[Solved] Grid throws ContentHorizontalOffset exceptions

[Jerry Kurata]

Hi.

I have noticed the following exception being occasionally thrown from my grid.  Can someone help me determine what could cause this issue?

Hi Jerry Kurata,

This issue has already been resolved. So, please try your application with the assemblies from our Q3 2010 release.

 

Kind regards,

Maya,

Thank you for the reply.  When it is is feasible I will try that build.

BTW, would this exception cause cells to appear blank?

Hello,

 This exception was just a wrong binding to a custom dependency property not related to cells - should not cause any problems with cells.

Thanks Vlad,

Would you happen to know under what cicumstances the exception appears?  We have not upgraded the library in several months and this exception had not appeared until we made some recent grid changes.  I am concerned that we are not doing something correctly.

Thanks,

Jerry

Hi Jerry,

 The exception should be raised during scrolling for recycled elements not part of the visual tree. I don't believe that you've made something wrong - this was just a case that was not handled on our end.
