Join them; it only takes a minute: Sign up Failed to load viewstate error after moving website to a new server up vote 0 down vote favorite I don't really know where http://stackoverflow.com/questions/580704/failed-to-load-viewstate-happening-only-occassionally-tough-to-recreate to start with this one. I am getting: `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.` after moving a website to a new server. The exact same code http://stackoverflow.com/questions/10008013/failed-to-load-viewstate-error-after-moving-website-to-a-new-server works on my other server. It happens when I submit one of my forms (but doesn't do it on all form submissions). Any ideas what can cause this so I have somewhere to look? Using: ASP.NET 2. EDIT: I am adding some user controls to a placeholder dynamically at runtime but this same code is working ok on my other server. I have tried clearing the controls in the place holder before adding new ones (as I saw a post about that) but it hasn't helped. EDIT2: It seems that the postback is just failing. It isn't going into the onClick code of the button either so something is deffintiely screwy .. If I try / catch the exception it seems that all the controls are still added successfully ... Setting my Dynamic UC's to EnableViewState = false resolves this particular error. EDIT3: Ok, I think I may have a handle on what is happening. For some reason on the old server the form action is default.aspx?action=amend but the new server is showing amend.html?action=amend so I think the re-write module is messing up in IIS. This would explain the control adding issue as well because the action is happening 2 times (I think). I will look into the Rewrite module and see if anything is wrong then post back. asp.net iis share|im

Failed to load ViewState P: n/a John Kirksey I have a page that uses an in-place editable DataGrid that supports sorting and paging. EnableViewState is turned ON. At the top of the page are several search fields that allow the user to filter the results in the grid. Say you filter the grid for records that have a certain condition set to "NO" (in this case a checkbox). In this scenario the search returns one result. If I then check the checkbox ("YES") and save it, I now get my message of "No records found" which is correct, because my filter is still looking for no. NOW, if I then resubmit the form, I get the following error: System.Web.HttpException: 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(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Control.LoadViewStateRecursive(Objec t savedState) at System.Web.UI.Page.LoadPageViewState() at System.Web.UI.Page.ProcessRequestMain() --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain() at System.Web.UI.Page.ProcessRequest() at System.Web.Util.AspCompatApplicationStep.System.We b.HttpApplication+IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionS tep step, Boolean& completedSynchronously) The only way to not get this error is to reload the page completely. What could be my problem?? Thanks in advance, John Kirksey Nov 17 '05 #1 Post Reply Share this Q
