How to apply filter on a RadGrid using ApplyExpression Event

[Web team]

Hi,

I want to create a combobox filter control instead of a textbox in RadFilter. I followed the steps described on this link:

http://www.telerik.com/community/forums/aspnet-ajax/filter/error-when-building-custom-radfilterdatafieldeditor.aspx

However the example on this link does not involve updating a a radgrid but only displaying result filter. Please help me fill in the codes (???) below so I can filter my Radgrid based on the expression produced by the ApplyExpression event:

protected void RadFilter1_ApplyExpressions(object sender, RadFilterApplyExpressionsEventArgs e)
        {
            RadFilterSqlQueryProvider provider = new RadFilterSqlQueryProvider();
            provider.ProcessGroup(e.ExpressionRoot);
            RadGrid1.DataSource = ???
        }

Thanks a lot.

i tried this one but it did not work:

RadGrid1.MasterTableView.FilterExpression = provider.Result;

anyone?
