Framework 1.1 ASP.NET smartnavigation problem with Panel

kevin · Jul 29, 2003

hi, all

it seems that smartnavigation has problem with the hide/show panel in the
aspx page,
I have three panel wih back/next buttons, the first two page works fine, but
at the last
page, all click on the buttons gives an error saying "Undefine" is null or
not an object.

what cauase that? because when I take off smartnagivation on web.config,
everything
works fine.

Smart navigation is known to have many issues, and is generally not
recommended (at least not for anything with any level of complexity).

Unfortunately Smart Navigation is really buggy

Instead, you can add this JavaScript to your page (I use it on my projects
and it works fine

)

The idea is that when client ever clicks something on the page, it's scroll
position is stored to hidden variable by using getPosition() function. If
postback happens, setPosition() is called and it restores the scroll
position.

----------------------------------------------------------------------
Put this in the <head> tags of the page:

<script>
function getPosition()
{
document.forms[0].hid.value=document.body.scrollTop;
}

function setPosition()
{
document.body.scrollTop=document.forms[0].hid.value;
}
</script>

And at the body tag, place:

<body onmousedown="getPosition()" onload="setPosition()">
<form id=WebForm1 method=post runat="server">
<input type="hidden" id="hid" runat="server" >
