Start Grid filtered

hey,

I have a grid and a filter. at the filter I define default values at the start (Date = Today).

But the grid is load with all details, today and yesterday an so on… Is it possible to load the grid with the default filter?

Maybe in php event onFilterint:

{MONAT} = ‘’.$MONAT.’’;
{JAHR} = ‘’.$JAHR.’’;
-> now: Press the search button ?

Thank you!

It is a old question. BUT, I need asign a global variable to a field of filter, and set readonly to a field of filter too.
It posssible?
