Start with the simple stuff. Make sure you have the EnableViewState property set to true on the disappearing controls. Also make sure that you have all your initial page_load code within an if block to check for postback, i.e. if (!this.IsPostBack). If that doesn't work, you can always check the value's of subsequent buttons and checkboxes on postback and repopulate prior buttons and checkboxes accordingly. - Arcond

Hi Graus, Thanks for the immediate reply Grauss. In the view source i found the name which aspx page refers to the usercontrol .So i hardcoded the name in the referring session "document.forms[0].Usercontrolname_html_cart.insertRow();" but still its not working. I tried with the alternative " document.all(""html_cart"").insertRow(); Even this is not working. One more thing is that im not dragging and droping the usercontrol in the aspx page . Im using another method to load the usercontrol when the applications starts. Please suggest alternate methods to make it working. with regards Sathyanarayanan
