capture the mouse down event of the item you want to drag around and save a handle to the element in the click handler (using the "this" pointer for example)
capture the mousemove and mouseup events of the document element and check to see if you have an element that is being dragged around (ie, the saved pointer isnt null) ... if so update it's position with the mouse until the mouseup event where you clear the dragged item handle

I use IE6 and on a specific event the ajax request is sent and when response come back the function showTbl() is called. This function is:
function showTbl()
{
myTbl.innerHTML = SOAPResponse.xml;
}
the xml content is about 2000 rows like that:
<tr><td></td></tr>....
The object myTbl is a simple table element and is eventually shown, but it takes more than 30sec to insert the xml content to innerHTML.
How can I decrease this time?
Thank You

You're gonna need to give a better example. To the best of my knowledge, the innerHTML property on TABLE elements is read-only on IE6 - so i'm not sure what myTbl is in your code snippet. I ran the following test, and found the table generated almost instantly:
<html>
<head>
<script>
var tableHtml = "";
function init()
{
for (var i=0; i<2000; ++i)
tableHtml += "<tr><td>The quick brown foxes jumped</td></tr>";
}
function fillTable()
{
var tableDiv = document.getElementById("tableContainer");
tableDiv.innerHTML = "<table>"+tableHtml+"</table>";
}
function runTest()
{
init();
fillTable();
}
</script>
</head>
<body onload="runTest();">
<div id="tableContainer">
</div>
</body>
</html>

I'm sorry, saying myTbl I meant to div.
Here's better example.
<table id='tbl' border='0' cellpadding='2' style='font-family:David;'>
<thead align='center'>
<tr bgcolor='#5D7B9D' style='color:White;'>
<td>
<input id='btn' style='visibility:hidden;' onclick='undo(); return false;' src='undo.gif' type='image'/>
</td>
<td>Name</td>
<td>Id</td>
<td>Area</td>
<td>Status</td>
<td>Date</td>
<td>Time</td>
<td>Arrival</td>
<td>Comments</td>
<td></td>
</tr>
</thead>
<tbody align='center'>
<tr link1='1'>
<td>
<input type='image' title='edit' src='edit.png' callId='no_call' onclick='editCall(this); return false;'/>
</td>
<td style='cursor:hand;' rId='1234567' onclick='getDetails(this.rId, this.parentNode.rowIndex, true);'>Joe</td>
<td>1234567</td>
<td noarea='false'>99</td>
<td statusId='not_located'>Found</td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</tbody>
</table>
Assume that I have 2000 of rows like that with 'link1' in tbody. I build this code in server and as I explaind earlier I insert this code to div in client. But it takes about 30sec.
At first i built this code in cliend according to details I received with ajax but it took about 2minuts.
I hope, this time I explaint more claearly my problem/question.
Thank You,

HI,
I am using update panel in my application.but i am facing one issue.
I have one page for new enrolment of members, and i have two user controls Step1.ascx and Step2.ascx. My functionality is that at a time olny one control is visible on the page and other will be hide. for eg when user fills all fields in step1 and press next button then step2.acsx will be be visible true and user Step1.ascx will be visible false. all this happening at postback.
both control is under update panel to avaid post back during change of visibility.
On Step1.ascx i have one javascript variable var_pageName and its value is "Step1".
I want to update this value during post back to "Step2" when Step2 user control visible is true and vise versa. but the problem i am facing is javascript value is not updating during postback. I had tried this with scriptManager.RegisterClientScriptBlock and also with scriptManager.RegisterStartupScriptBlock by palacing it on both Usercontrol level and also on page level.
Please help as this is ver y urgent.

I am working on soapextension that compresses soap message.
I am stuck at only one stage now. When I get response from webservice....on client at -BeforeDeserialize stage when I try to copy original or old stream to temp stream so that I can
de compress it, I get 'Stream dose not support seek operation' error.
Has any one come across smilar issue ...that while altering stream you could not capture it properly when client recieves it from server
debugging
This code will create new file for input and output each stage. You can see that till that point message is getting compressed and de compressed properly. Sort file by Date created

Probably install the ASP.NET AJAX extensions.
However, you quite plainly do not need VS2008 to create ANYTHING on the project level to be able to use AJAX, you just need a project that imports that dll if you want to use the Microsoft AJAX enabled controls.

Hi all,
I need a suggestion to solve the below problem.
intXOffset = window.event.offsetX;
intYOffset = window.event.offsetY;
the above code works good in IE but not in any other browsers 
how to write a browser independent javascript for this. Also there is a problem with this code. The function containing this code is called onLoad of the body and onclick of a image.
Also any one suggest me a URL from where i can learn browser independent javascript.
Thanks in advance

I want to know that what will be the server in case of server side javascript.
I know the code for that but my code is not running on IIS server.
If server is tomcat than what will be the structure of that folder, because in tomcat we must need web_inf .
