ASP.Net Page loading twice

Posted in .Net, programming, software by Ahmed Siddiqui on June 2, 2008

If you are observing load event twice in a post back in ASP.Net page, check the following:

  • If Page_Load handler defined in Codebehind then AutoEventWireup property should be “false”
  • Check if you have mistakenly multiple event handlers registered for an event
  • Src or ImageURL attribute of your image control are defined and not empty (you can put %20 for blank)
  • bgColor or background is empty

Last two problems usually appears in one browser while disappears in other.

    This is a really annoying problem that keeps bobbing up now and again for me, the majority of the time it is caused by one of the problems outlined by you – another cause of the double postback I found out today was SmartNavigation, I spotted an iframe in the source code with the ID ‘__hifSmartNav’ – removed it and it solved the problem.

    In my case my page loading twice caused it to log the user off so it was more than an annoyance. Three days of searching to no avail…finally found your post and it turns out my problem is an image without the ImageURL attribute set. Thank you!
