Viewstate error on sharepoint custom page

Created a custom aspx form in my sharepoint application. Put that under layouts folder. Placed a gridview control on it and started receiving the following error:

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.   at System.Web.UI.Control.LoadViewStateRecursive(Object savedState)    at System.Web.UI.Control.AddedControl(Control control, Int32 index)    at xxxxx.SharePoint.EventsMgmt.BookingForm.RenderSearchResults(DataTable roomAvailabilityTable)    at Telstra.SharePoint.EventsMgmt.BookingForm.OnClickOK(Object Sender, EventArgs e)    at System.Web.UI.WebControls.Button.OnClick(EventArgs e)    at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument)    at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)    at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)


Set enableViewState=false in gridview tag on the aspx page…….(not code behind). solved the problem.

Hope this helps-
