From: L . Lee Saunders on 5 Aug 2010 10:54 HELP! Any time a control that posts using DoPostback (ie, via javascript) the event is fired twice on the server. Example: Regular asp:Buttons do not fire twice but autopostback dropdownlists do as well as <Button runat="server" OnServerClick="asdf"> controls. INFO: asp.net 4.0 C# dev machines: both XP & 7 master pages with lots of ASCX controls on each page for control reuse. (Though, the double fire even happened on the login page where there are no ascx controls) Please help, this is bringing down the project. -- L. Lee Saunders

I've not moved to .Net 4 yet, so this is only a suggestion: Can you produce a simple example with say just one control on it which exhibits this behaviour - starting from a new empty project? If not then its probably related to something that's been added to the page or more likley in your code-behind. -- Brian Cryer http://www.cryer.co.uk/brian |
