I have seen several threads on sorting when using a converter, but none specific to my question. I'm currently using Q1 SP2.
I am retrieving entities via WCF RIA Services, and combining two columns into one column of the RadGridView using a converter. The converter requires that I pass in the entire entity, and the sort for the column can only be based on the result. Is there now a solution for binding the entire entity to a column, converting the entity into the actual column value, then sorting on that value?
Here is my specific case. The entites returned from RIA Services have two DateTime fields. The column is bound to the full entity, and the converter selects which of the two dates to display in the column. That is all worikng fine. However, I want to sort the column based on the date selected by the converter. Any solution?

Hello GEB,
In your case using the Custom sorting approach would be as close as we can get.
This includes handling the sorting event and writing a few lines of your own sorting logic to be performed . This way you override the default sorting .
In case you are not already familiar with this approach and need further assistance, just let me know.

Thanks for the very quick response. Can you point me to the best reference for writing a custom sorting method?
Also, for the derived column, sorting is not even presented to the user. They can sort on all other columns except that one. If a custom sort method is written will it allow the user to sort on the derived column?

Hello GEB,
The sample attached demostrates the custom sorting applied in a scenario with a value converter.
