you can call __doPostBack function,
it works like an asp.net button.
Glad to discuss with you and best wishes.

Traditionally, you would wrap the button inside a form, and the button would actually be of type submit.
Then, the form values get POSTed to your server from which you can parse via the Request.Form object, and from there, simply insert into DB.

There are various way to implement it. Either you can pass it as query string or you can store it in session variable.

Buy a book on ASP.NET, and read it. Try reading the forum rules, too.

i want to make video files DRM protected so anyone can watch the downloaded videos only when logged into the website. videos can be watched online or saved and distributed by dvds, but the only way to watch should be the site authentication.

Hi,
most barcode readers work by using keyboard emulation. If you press the button on your barcode scanner, the scanner will read the bar code and simulates a user input using the keyboard. You could place a texbox on your page, setting the focus on this texbox. Then the user uses the barcode scanner. This will put the barcode into the textbox. If the user presses a button, the input will be submitted to the application and you can handle it. (Or send the form automatically 2 seconds after the first input (done with js), this will avoid that the user has to press a button).
Does this help you?
Regards
Sebastian

Dear all
I am developing a website for a client in ASP.NET, Client wants to protect his webpages from copied. He asked me the following
1) Stop right click
2) Stop Context menu
3) Stop user saving and viewing source using "Save Page As" and "Page Source" in firefox. "Save As" and "view source" in internet explorer.
4) Stop taking print screen and saving it as image
In this i have accomplised the tasks 1 & 2 using javascript. is there any way to do the 3 & 4 tasks. If not possible please drop me the exact reason so i can make the client understand.
Thanks in advance
Regards

I doubt 3 and 4 can be accomplished -- at least not in every browser.
And there is no way to completely protect the XHTML/CSS/JavaScript source (your serverside code is safe though, unless the server itself is compromised).
If someone has the will and know-how to get it, they will.

You can disable the menubars and tool bars using opendialog method.
If i were you, i would create a new startup page and use opendialog to launch the home page diabling the menu and tool bars.

You might be able to accomplish part of task 3, but than can also easily be undone by simply requesting the page using some other program than the browser. All that is needed is a single line of code:
new WebClient().DownloadFile(url, fileName);
Anything that the browser can read can also be read by other programs, so there is no way that you can keep anyone from reading anything that you want to show on the web.
Task 4 is not possible at all using Javascript, as it's not a function in the browser, it's a function in the operating system.
Despite everything, the person most likely to be fooling you next is yourself.

There is no way of preventing a web page being copied. The idea is that the source is easily accessible and trying to prevent the user from doing this won't really do anything, since the nature of the Internet is such that files that can be viewed in a web browser can be accessed by anyone.

You think you've accomplished one and two. I guarentee you that I can get around it if I wanted to.
I suggest you shouldn't be taking clients if you can't answer their questions.

Hi,
The following sample will help you out for the points 1 and 4 for sure. Please try this and reply.
<html>
<head>
</head>
<!-- To disable Print Screen feature -->
<body onload=setInterval("window.clipboardData.setData('text','')",2) oncontextmenu="return false" onselectstart="return false">
Test Text
<!-- To disable right click in the web page -->
<script language=JavaScript>
function clickIE() {
if (document.all) {
return false;
}
}
function clickNS(e) {
if (document.layers||(document.getElementById&&!document.all)) {
if (e.which==2||e.which==3) {
return false;
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS;
}
else{
document.onmouseup=clickNS;
document.oncontextmenu=clickIE;
}
document.oncontextmenu=new Function("return false")
</script>
<!-- To Disable Text Selection -->
<script>
function disableselect(e){
return false
}
function reEnable(){
return true
}
document.onselectstart=new Function ("return false")
if (window.sidebar){
document.onmousedown=disableselect
document.onclick=reEnable
}
</script>
</html>

You can use Ajax.
Use AjaxControlToolKit[^], where in you can place server side controls in UpdatePanel, and write serverside code.
Thus you can avoid postbacks.
I hope this helps you.
Cheers,

store two tables data in some variables when page is loading.
then use javascript to change items in second dropdownlist.
here are steps:
1. store country and state data in two hidden fields, or two variables in JavaScript.
2. write function to change items in second dropdownlist.
...
Changing Select element content on the fly

Glad to discuss with you and best wishes.
