No, you don't. You can't access any server control at all from Javascript. The code is accessing the html elements that the server control has rendered.
The server controls only exist on the server to create the html page. Once the page is created and sent to the browser, the server controls doesn't exist any more.

You can't. You have to access the properties of the html elements that the control has rendered. Use the selectedIndex property to get the index of the selected item, then use that to get the value of the selected item.
Example:
var sel = document.getElementById('idOfTheSelectElement');<br />
var value = sel.options[sel.selectedIndex];

When your server side code generates the script for the page, it can generate script to call the method in question when the page loads.

When you run in IE, View the page source of IE see the path of that image.
and then as per that path you need to set in code like.
./images/1.jpg like that.

hi , i have build an ASP.net application using Enterprise library 1.1. Curremtly i was using sql server 2000. Now i have to take my DB to sql server 2005. my question is that my current application will work with SQL server 2005??? Is enterprise library 1.1(june 2005) work well with SQL server 2005????? please reply soon...

You've asked this in two forums. The other one is the right one. What DB you use has nothing to do with ASP.NET. Your app should work fine, but you should run your unit tests to be sure, because there are changes to T-SQL, and you never now for sure.

hi
in one of my webform's project , user can select some choice from a list.
after each select, that item insert into a temp table in my database. and ...
at last ,if user click ok button ,all selected things insert into main table.
if page closed or exit with any reason before user click ok or cancel button , in code temp table must be clear.
my problem is can not find any thing such as an event for times when user exit from the page.
how can recognize in asp.net when user exit from a page ?

In ASP.NET, you can't, but you can write AJAX code that sends a message to the server when the browser is closed, and of course you can integrate this into your ASP.NET project, although it won't use any ASP.NET libraries or code behind ( unless you choose to emit your script in your code behind ).

tanks.
exactly this solution was in my mind.
and now found is right

To handle the Browser close event you will have to write a javascript function that handles it and call the function on the OnBeforeUnload client event.

Hard to say based on the half snippet you offer here. What makes you feel you should be getting something back ? What does your code look like ?

Scott Mitchell probably has... 
What problem are you having ? Do you have the source code from his site, or have you had to enter it.

Are you sure you can't download the code from the web ?

Well, is that because your expectations are too high ? What *does* it do ? Is it blowing up, or just not meeting your needs ?

My problem is,
I form a string...
string filter="dataView"+someIndicator+".RowFilter='someField="+someExpression+"'"
... and now I want execute that string. What should I do?
@filter
or
Eval(filter) ?
I would be very thankful if anybody could give an advise.
Thanks,
marijus

There is no such thing as an Eval function in C#. You should rethink the solution.
You can for example keep an array or a list of the data views that you create, so that you easily can access them by index.
