I already checked and yes I am getting the right path.
function PreviewImage(wThis)
{
alert(wThis.value);
document.getElementById("img1").src=wThis.value;
}

When you alert image path are you seeing path like c:\somefolder\somefolder.jpg ? If yes you need to replace \ with \\ to make it work.

What's witht he CDATA[[ ]] ? This is Javascript, not XML...
anyway... I suspect this may be a Firefox issue... it works fine in IE, and there is nothing wrong, in principle, with what you're doing.
FF has an option to prevent scripts from updating images, but this is turned off by default - still, I can't help wondering if there is bug somewhere around that...
Be interesting to know if you ever get it sorted...
have you tried Googling for "javascript image preview" or some such? I vaguely remember coming across a script for this some time back...

I try to googling a lot, but with no success.
It doesn't preview image, can you post your html page because if it works to you, it should work to me too.
Perhaps this is a configuration problem?
I am working with ASP.NET 2005.
Please help, thank you

My code is the same as yours, in essence - as I say, it works in IE but not FF. This has nothing to do with .NET - it is pure html/javascript.
<html>
<head>
<title></title>
<script language="javascript" type="text/javascript">
<!--
function PreviewImage(wThis) {
document.getElementById("img1").src=wThis.value;
}
// -->
</script>
</head>
<body>
<form>
<div>
<input id="File1" type="file" onchange="PreviewImage(this)" style="width: 240px" /></div>
<br>
<img src="" style="width: 96px; height: 96px" id="img1" name="img1" /> <br />
</form>
</body>
</html>

I copy the code to notepad and save as html. When I ran it, I got an Information bar as following:
"To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer. Click here for options."
After click popu up the 3 options:
1) Allow Block content...
2) What the risk?
3)More information
I click the first option and click yes for stop blocking and then the code run well.
So I believe that this is the problem, How can I unblock through my code so everyone will be able to preview images on his computer?
Thank you.

You will get this security warning if you run your HTML file by double-clicking it - but if you run it through a web-server it will not appear.
This will not be a problem for 99% of users. A small number may indeed have their security settings set to block all javascript, but very few, and there is nothing to can do about that - it's their choice, and they will know what they are missing out on.
So don't worry about it.

Saving HTML page to client machine ? To remove those images, you need to look for images to be removed using regular expression and replace it with blank value.

I presume that you know all these 3 buttons name. When you are creating HTML find these names and replace it with blank value.
Still I didn't understand how you will save HTML file to client machine, I don't think that ASP.NET will be having write permission on client drives ?

Sorry,Html page'll save in local systems only.
I am calling the following javascript function on the save as html button click event
function saveashtml()
{
window.document.execCommand('SaveAs',false,'C:\\file.html');
}
This function simply reads the entire page and save it into html page.

After saving the file open it using javascript and remove these unwanted image tags. Check this[^] for opening files in javascript.

You could use AJAX to get the values, and set the selected box using javascript. Or, you could set the selected item in the selected index changed event handler.

Set MaintainScrollPositionOnPostback="true" if you are using ASP.NET 2.0.

To reiterate my answer - if you don't want to use AJAX ( and it would be nice if you did ), then you should set the selected item in your code behind, in the event handler for the first drop down list changing, the one that fills the second drop down list. If there's no property on the server side, you could certainly inject client side code that runs when the page has loaded.

Why don't you just use a variable to store the information pointing to the control which has focus?
When page reloads just fetch the data from the viewstate.

You'd need to use a repeater for that, then you can write the code to build the table as you're hoping.
