The Gridview gets bound from  RIA  domaindatasource .  My telerik version is 2011.1.315.1040.

What can cause this behaviour ?.

Hello Ole,

By default the sorting feature of RadGridView gets disabled when it is not possible to determine any order for the elements of the respective type. Designing the type to implement IComparable should fix this problem.

HI,

The sort feutures are not disabled, at least the column headers sort arrows moves.(But nothing happens in the gridview) And as I am binding to a ria domaindatasource, it should be able to sort.  I have done that before.

Are these assumptions not correct ?.

Hi Ole,

Unfortunately I cannot pinpoint the source of this issue having only this xaml code. Would you please send me a simple demo project that replicates the issue, in order to help us provide better support to your case. Please, excuse me for the inconvenience.
