ASP.Net + MVC + VS 2008

Question

I am using asp.net MVC with Jquery.

I use RenderPartial method to load control and open as modal dialog. After submit small form on modal dialogue i want to get focus on same dialogue in case of error.

Javascript

$(function() {          
            $("#dialog").dialog({
                bgiframe: true,
                height: 180,
                width:380,
                modal: true,
                autoOpen: false,
                resizable: false
            })
        });

Any idea.
