MaintainScrollPositionOnPostback, EnableEventValidation and IE5
-
Hi, I have an ASP.Net application and I have enabled the above two properties on my page. Everything works fine on every OS-Browser combination, but on Windows 2000, with IE5, 1. As soon as the page opens up, I get a JavaScript error "Object doesn't support this property or method". I identified the problem is because of enabling MaintainScrollPositionOnPostBack, which tries to change the submit property of the page: I set the property to false and all works fine even on IE5 theForm.submit = WebForm_SaveScrollPositionSubmit; 2. The page implements ICallbackEventHandler, and has script callbacks at various intervals on the page. When the page submits, I get the error "Invalid Postback or callback argument...use ClientScriptManager.RegisterForEventValidation in order to register the postback or callback data for validation" As I said, this problem only occurs on IE5, but I searched around and there are not a lot of people complaining about this. Has anyone else faced this problem with IE5 before, or can I avoid this problem somehow? Thanks, Praveen
