Refresh with ajax an img src

I use javascript hints for my textbox and when page loads I set that, but after submiting data for example in the case of error in input and need for inputing again the data it doesn't show the hints, which means that when ajax sends Httprequest and gets Httpresponse and refreshes the update panel , that panel doesn't accept loaded jscripts again, so they should be loaded again.

I do not know how to do that in asp.net, any tips or recomendations?

I have found an odd bug in my application.  I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.

Now the strange behaviour in firefox and not IE:

If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.

Anybody had the same problem or does anyone have a fix out there?

Your help would be appreciated.

Thanks

I am writing a ASP.NET C# application and using a AJAX timer in order to refresh some if the data every couple of seconds.

Whenever the timer function is called, it looks like the whole page is rendered again. For example, I have a list of tabs, the selected tab is not selected anymore.

I need to keep the selected tab 'selected' after refresh.

How can I achieve that?
I am attaching the relevant code.

my aspx:

ASPX
--------
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="InternalMonitorTool.test" %>

hello! I need help on my school project

Autopostback works but when one dropdownlist is selected the page refreshes. When the user select one dropdownlist, another dropdownlist will then populate if not its empty. After submitting the form, selecting dropdownlist will remove all the validation message. What i want to achieve is to have javascript to manually postback instead of using autopostback so that the validation message will still remain after selecting from dropdownlist but without using of AJAX as server cannot support :D!! ty
