I tried to change the gallery folder dynamically on user selection

 

so I made an Update panel and made the     GalleryBrowser1 as its child

 

and where the user tries to change the path i wrote

 

       updatePanelGalleryBrowser.Update(); 

 

as i run this the  GalleryBrowser1 wil not show any pic and is as shown in the image attached. Please help!!!
