jQuery Grid Plugin - jqGrid

Hi, i have a jqgrid (jqgrid1) and i changed the navgrid addfunc and editfunc. when add or edit button is clicked it will show a jquery dialog (jqDialog). inside jqDialog is another jqgrid (jqgridChild). the issue is when i try to click the add button (form editing) on the jqgridChild, the form is shown at the back of the  jqDialog. and at first i cannot use it coz the jqDialog modal:true, so i set it to false. now i can use the form. but how can i make its show above the jqDialog?

tnx...
