I get the latest service tag for SL 2012 and updated all assemblies for bugs. then I put the app to live production. then I got lots of error report when users try to sort data in xamgrid: drag and drop a column header for sorting. the error is:
Object reference not set to an instance of an object.
I try to debug it, but I can't get in. So how to resolve this issue? It's urgent. Quick solution please.
Thank you. I do have some customized code on xamgrid. it works fine before the service pack updated. the problem fixed. Thanks for the notes.
