Hello.
I am filtering my dataset in db, not in the IIS (RadGrid), because it contains millions of rows. During the RadGrid_NeedDataSource event, I am clearing the FilterExpression property and thus RadGrid is not resorting the dataset again. (Is it right?)
The problem is if the user does some sorting, next time the FilterExpression is empty although there are some values in filter row and also the option NO FILTER is NOT selected (another filter function IS selected).
Why?
Thank you very much.
Tom

Hi tomas,
One possible option in this case would be to set the filter expression on initial load, as shown here. This can be done in PreRender, to ensure that it is persisted on each page cycle.
I hope this helps.
