Hello Friends, How use javascript function in code behind file aspx.cs My function Event: onbeforedeactivate();

[varshavmane]

Button1.Attributes.Add("OnClick", "javascript:return FunctionName();")

No dear thats not right question do one thing Write your javascript in content placeholder only and try to run the application and see does it call that function after proper event

I want call this function Window close. not for button click.

[varshavmane]

which window?

[Christian Graus]

Not sure if the answers you have got will help - you can't call javascript in your code behind. You can emit javascript as part of the html you send to the client to force a method to run when the page is rendered. But, js only runs on the client.

Current Window Means Open default.aspx. when close the button then call fuction.

It is not a good practice to call the Javascript function in the codebehind file. Just put the javascript in the content place holder and call it.

SSK. Anyone who says sunshine brings happiness has never danced in the rain.

What exactly u want to do, I mean why u want to call javascript function on window close as u can give it in body tag also, somewhat like this: function CloseWindow() { alert("1"); }

[Abolfazl Sheikhloo]

How can you use javscript function in code behind only thing that you can do in code behind is you can register javascript for perticular control i thing there is some misunderstanding .

The only way to let your code behind know that the window was closed, is an AJAX call.

[Rinki Mukheraji]

No, it can't be done. As someone has shown already, you can call javascript on a page close. Only AJAX can call the server.

I percieve that English is not your first language, so I will be polite. You've been told the only possible answer, and belligerently asking over and over is not going to change the way every browser in the world works, or the nature of HTTP, to contrive to create the answer you're trying to find. AJAX is your only option.
