cast exception when sorting after grouping

[Dave Smits]

I have an databounded radgridview with autogeneratedcolumns on false and DataLoadMode="Asynchronous". when i do first a grouping and then try to sort by clicking on the column header i get an cast exception. is this an known issue?

i made a demo project and you can download it from here: https://skydrive.live.com/redir.aspx?cid=d1ba3c73be854a97&resid=D1BA3C73BE854A97!472

Hi Dave Smits,

 

We have recently had similar issue which was immediately fixed. I have just tested your project with binaries as part of our latest hotfix (2011.2.823.1040) where such a behavior cannot be observed.
I am attaching your updated project for further reference.



If you need any further assistance do not hesitate to contact us!
