How to achiev these two things.... ...

Benjamin Smith

Copy and paste this code in the HTML section of the page

1. Why I am using hidden varaible here?
Currently user can click on hide/show link. If the application is in display
mode (I mean the hidden data is displayed) and if the user clicks the
button, the post back happens and the user selected display mode will be
gone. To avoid that I am trying to keep the user opted mode using hidden
control and trying to restore the same value after postback. How to do that?

2. Currently this part of my code appears almost at the end of the page
where user has clicked vertical scroll bar to get into this section. After
scrolling down if the clicks the hide/show link the data will be
displayed/hidden but the user will be shown the top of the page. Some thing
like my smart navaigation is not effective. I know I am not posting the page
back when the user clicks on the hide/show link. But how to restore the
vertical postion of the form when the user clicks on hid/show button.

Your comments and suggestions are highly appreciated.

Benjamin:
Your 2nd problem can be fixed by changing the <a> tag to:
<a href="javascript:hideshow('row5')">

the problem with yours is that you have an href="#" which means top of page,
so the onlick event fires then the link is followed (to the top of page),
the syntax provided will work in all browsers.
For your first problem I think your on the right track. Store the value in
a hidden field, and toggle it in your codebehind, something like:

function hideshow(obj)
{
if (document.getElementById(obj).style.display == "block")
document.getElementById(obj).style.display = "none";
else
document.getElementById(obj).style.display = "block";
document.getElementById("hdnRowSts").value =
document.getElementById(obj).style.display;
}
and in your codebehind, simply putting the following in your page_load
should work:

If Not Request.Form("hdnRowSts") Is Nothing Then
row5.Style.Add("display", Request.Form("hdnRowSts"))
Else
row5.Style.Add("display", "none")
End If
although you might wanna make sure Request.Form("hdnRowSts") is a valid
value...

Karl,
Problem 2 got fixed as per your suggestions. Thanks a lot.
Problem 1. I do not understand how one can access the client side Id in a
server side code.
row5.Style.Add("display", Request.Form("hdnRowSts"))
When I put the above code it says variable not declared.

oh..sorry, add runat="server" to the row and declare it as an HtmlTableRow
....thus making it a server-side control :)
