I want to create a combobox filter control instead of a textbox in RadFilter. I followed the steps described on this link:
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:
sender, RadFilterApplyExpressionsEventArgs e)
RadFilterSqlQueryProvider provider =
RadGrid1.DataSource = ???
Thanks a lot.
