How to refresh GridView - problem in ASP.net

Hello, I have some problems with my application.

I have dropdownlist connected to a DataSource that retrieves data from a stored procedure (and that works fine). Below my dropdown list I have a GridView, also connected to a DataSource that gets data from another stored procedure (with a parameter). Data source is set to call this stored procedure with parameter equal to the value of my dropdownlist.

And the problem is that when I load page, grid view is not displayed at all.

How to refresh my grid view, so that when I load page it will be displayed and showing the data taken from stored procedure called with parameter equal to the value of 0. element in the dropdownlist?

Thanks in advance for any help.
