To check if the state of the data has changed the page would have to be re-loaded and sent back to the server.
The only way to do this is to have an automatic refresh.
Woudl that be suitable?
But then you have to decide how often you want the page to refresh.
Is the user going to constantly have the same screen in front of them, if they are moving about its not so much a problem.

You can use Ajax methods in the backend for a particular time interval, say every half-an-hour, to check the database and find whether any changes has been made. If there is, update the same.
If it's too difficult to check the updation, just load the data from database everytime. But this may affect the performance.I'm not too sure about it.

So you have only three list box.Right?
Bind First list box on page load event
if(!ispostback)
{
//First List Box
}
Now on first listbox SelectedIndexChanged event,check items is selected or not. if it is selected then get records from database depending on selected value and bind second ListBox
do same code on second listbox SelectedIndexChanged event

Why you need property of gridview to display confirmation message?
You can also display confirmation message on OnClientClick event of Button control.
OnClientClick="return confirm('ARE YOU SURE......?');"

You could also try the ajax extender which you can attach to a button or other control

I intend to show CPU time on a Dundas Gauge Control. So i get the CPU time; but the value is always return 0; i survived the fd from 0 but now it returns 50 sometimes 100.
but if i check the
CPU_1PerformanceCounter.NextValue(); on Quick Watch i see the reel values. if i press the REGENERATE button; it returns new reel value but
fd = CPU_1PerformanceCounter.NextValue(); never works; so it is not set the reel value to my fd variable.
PerformanceCounter CPU_TotalPerformanceCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
float fd = 0;
do
{
fd = CPU_1PerformanceCounter.NextValue();
} while (fd == 0);
e.RealTimeValues.Add("CPU_Total", fd);

Are the files in the correct location, i.e. the root folder of the website?

Plain JavaScript can not give this power for your webpage. You may need to use an ActiveX Control.
Check out http://www.chestysoft.com/ximage/twainupload.asp[^]. It is a commercial ActiveX Control but gives a trial version for you to evaluate anyway.

If you want to use these types of char in code,You simply add '@' char.
For Example
string MyString = @"Text User\Directory\";
