RadGridView Load Time, and Filtering with DateTime

Hi,
After migrating all DataGridView to RadGridView, I have other question:

When the form using RadGridView first viewed, the UI freeze quite long (I'm tested in my P4 machine about 3-5 sec) before showed. Is there any method/trick to pre-load RadGridView say when I showing splash screen, so the delay wont happen.
I have field DateTime type, when I enable filtering and enter filter value it's was ok, but how to clear the filter value ?
How to alter Group Text, as far I known it was value of ColumnHeader Caption or Column FieldName.

Best Regards,
Fakhru Rahman
