I have this dropdownlist which its selectedvalue is set as a datasource parameter. That dropdownlist is also set to auto postback to refresh the datasource and the binded grid. Everything works fine but how can I make the dropdownlist to retain it's value after the postback ?? Thanks

Are you checking the value in the Page_Load or in the event for the DDL?  Sometimes, I have found that the value isn't available in the Page_Load, but it is in the event for the DDL.

Also, are you doing initialization outside of an IsPostBack block.
