I have added dynamic controls to the webpage its getting added on the selection of dropdownlist.
Its working fine: when user is entering data through that controls is getting stored properly into the database.
We are also allowing user to edit that data onclick of edit button which is added in the datalist but on click of update its throwing me error like

"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."


I am also providing Enableviewstate="false"
still its not working....
Please suggest solution.....

Thanks in advance....

Are you creating your controls in the OnInit event of the page?

I have always had problems unless I create the items in the OnInit event. It is the proper event to create dynamic controls.
