Hi Alex,

  Such a code works fine at my end.
  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. Can your data be sorted on any of the bound 'ID' or 'MessageTypeID' properties?

All the best,

thanks for your reply

What do you mean by "Can your data be sorted on any of the bound 'ID' or 'MessageTypeID' properties?" I want users to be able to sort data at any time by clicking at the column header

My domain service returns an ObservableCollection. I wonder if it is anything to do with that?

I still have this issue. I tried using RadDomainDataSource and my data does not load at all. Could you share the code you tested please?

Hello,

 Please take a look at this forum post where a similar topic is discussed. There is a sample project attached as well.
