Hello Everyone,
i was currently working on the dotnetnuke, while developing a page i used updatepanel and placed an imagebutton inside update panel control and created the imagebutton click event and display a message using response.write(); when i run application it displayed an unknown error. saying...

An error has occurred.
DotNetNuke.Services.Exceptions.PageLoadException: The state information is invalid for this page and might be corrupted. ---> System.Web.HttpException: The state information is invalid for this page and might be corrupted. ---> System.Web.UI.ViewStateException: Invalid viewstate. Client IP: 124.247.222.201 Port: 30567 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 ViewState: . . .... ---> System.FormatException: Invalid character in a Base-64 string. at System.Convert.FromBase64String(String s) at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString) at System.Web.UI.ObjectStateFormatter.System.Web.UI.IStateFormatter.Deserialize(String serializedState) at System.Web.UI.Util.DeserializeWithAssert(IStateFormatter formatter, String serializedState) at System.Web.UI.HiddenFieldPageStatePersister.Load() --- End of inner exception stack trace --- --- End of inner exception stack trace --- at System.Web.UI.ViewStateException.ThrowError(Exception inner, String persistedState, String errorPageMessage, Boolean macValidationError) at System.Web.UI.ViewStateException.ThrowViewStateError(Exception inner, String persistedState) at System.Web.UI.HiddenFieldPageStatePersister.Load() at System.Web.UI.Page.LoadPageStateFromPersistenceMedium() at System.Web.UI.Page.LoadAllState() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

i thought error would be of update panel, so i removed update panel and ran application, but in vain again the same error occured, i dont udnerstand why this error is occuring what is the problem with the page, even in the web config i tried change the and also false but that also didnt helped me..

Please can anyone solved my this issue, because i have almost completed developing page but this is creating a big issue for me...

I'm new to DNN module development (working on my first module now), but I encountered this error frequently at first, but not so much any more.  I think what I've figured out is that I only get this error if the version of my module that is displayed in the browser is out-of-sync with most recent build of my module code.  So now I exit and restart my browser anytime I have recompiled the module code.
