We are using the Telerik Treeview control and intermittently we are getting and invalid viewstate error. Here are some of the details of the exception:
Message: Exception Type: System.FormatException
Exception Message: Invalid length for a Base-64 char array.
Exception Source: mscorlib
Exception Target Site: FromBase64String
(Outer Exception)
Exception Type: System.Web.UI.ViewStateException
Exception Message: Invalid viewstate.
__EVENTTARGET RadTreeView1
__EVENTARGUMENT {"commandName":"Collapse","index":"43:0:0:0:0"}
Any ideas why this error may be happening?
Thanks
