Hi,

I am dynamically loading a usercontrol in which there is some linkbutton and I am assigning postbackurl value of the link buttons. which is working perfectly in Asp.Net but here in dotnetnuke it is giving error that....

A critical error has occurred.

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 unable to understand that why actually this is happening and What does this error means and how to solve it. Now I am in big trouble now and requesting you to  help me to solve this problem .

Thank you...............
