Controls inside the dynamically added web user control does not retain there value on post back caused by the dropdown list

Question

i am dynamically adding and removing a different user control from a to a place holders.

The user controls have lot of asp.net controls like cascading dropdowns with autopostback true.

The whole page is in a update panel.

After every postback i again add the control added previously and the which control is added previously is maintained in a view state.

The problem: Only first time the content in the textboxes get cleared after the first postback(caused by changing the dropdown)

Any help is appreciated

You need to make sure that your dynamic controls are being added in the Page_Init event in order for them to retain their data.
