CasdingDropDown

Question

Hi First to introduce my application, where I am using cascadingdropdown ajax control. In my application, I have one Page, with update panels on it. Whenever user click on any menu button. I dynamically load respective usercontrol, according to current selected menu. Usercontrols that I load, are actual controls where user interacts like login control, registration control etc etc. On one such user control I am using cascadingdropdown ajax control. Where user can select items and then edit it by clicking on by clicking edit link button. Problem is, whenever user select a value, and click on edit link button, it lose it selected value. in other terms viewstate information got lost. I test same control on another test.aspx page. where I just put this control on the page. statically. Not a daynamic loading. on that page it is working good. But with dynamic loading of usercontrol it is creating problem. I mentioned above. any Idea????? Please I am struggling with this problem since last 3 days. I am worried about it. Regards, Azam.
