Call a server-side method from JavaScript

[neualex]

Folks,

In ASP.net (using C#), you can have a server control to call a defined method. (ie. You use a Button server control, you can call the OnClick method).

How can we call a defined method (on the server side) using JavaScript?

I have such requirement since when I have a dialog box on the client side (OK/Cancel message box), I need to call a defined method on the server side. (ie. Delete a record, accept a transaction, etc.)

Any suggestions/comments is appreciated. Thank you.

you cannot. you need to use an ajax request to call a service/uri to return text to the client and then process the data on the client.

so in this case you want to move the code in the button's click event to either a static web/page method or webservice. for more information google webforms ajax.

as an FYI the asp:UpdatePanel is simply a full postback wrapped in an ajax call, so there is no preformance gain, or optimization with UpdatePanels.
