Advanced search & dynamic search

I open my grid with the advanced search to select a date range. The table has 200.000 records. Otherwise it takes to long to load the page. On the grid I use the dynamic search also.

If I select “Use Iframe = no” at the “Application modules” then I get the error “invalid data” if I use the dynamic search on the grid. When I select “Use Iframe = yes” I won’t get that error.
