asp.net page load twice problem

Hi there

I have one application use C# for asp.net, when I debug and write code
inside the page_load, it is loading twice, also I put IsNotPostBack, it
still load two times, any one have the same problem, and how to solve it?

by the way, I am using asp.net 1.1 version.

Thanks

Tony, I had this problem today and spent quite a few hours on it.
Finally I found out it was one of the <td> attributes that was causing
the problem. The "background" attribute was assigned a color code,
where it was probably expecting an image, a file, or something. Here
is the partial code:

<TD valign="bottom" align="left" background="#B6C8DE">

bgColor, not background, should be assigned a color code. But when you
cut and paste in a hurry in the Properties Window in the .net IDE,
sometimes that happens. Your page may not have the same problem as
mine, but it most likely involves an error condition, or a bad
reference.

I encountered this, too (with having an empty background value). This
seems to be a problem with alternative browsers only as it did show only
in Firefox and Opera.
To me it seems like the parser is skipping the page or something - and
requesting it once again to be sure the data send was not skipped or so.

Hi guys (+/girls),

I too had this error, and after some hours of debugging I found out, it was because of an empty src-attribute in an image-tag, e.g.

<img src="" alt="" />


In the end of my pageload, I was setting this value dynamically via javascript, which is why I didn't figure it out at first. But I hereby confirm, that at least firefox will reload the page (silently, though) if this "error" is present. The problem wasn't there in IE7, and I haven't tested other browsers.

Hope this helps somebody.

Regards,
Frederik Schøning

Thank you Frederik, your solution solved the problem for me.

I had src="" in an IMG and also an IFrame, I don't know if the iframe also causes it. It was only affecting Firefox.

I would never have solved it without your help!

Use !IsPostBack event in page_load & write the code or call the function within that block like:

page_load()
{
if (!IsPostBack)
{
write the code;
}
}

I think its working

I faced the issue of Page_load hitting twice in FF (3.5) only.
There were no problems with the html tags/images etc. The page had a blank link to stylesheet
like

<LINK href="" rel="stylesheet">

This causes Firefox to reload the page, thinking it lost the css tag in an error.
As long as you dont have any post back specific processing, this can be annoying

Thanks guys! I learnt more about Firefox behaviour, and eventually solved a bug
