Call ASP.NET Function From Javascript?

Anonymous User234927-Dec-2013

I'm writing a web page in ASP.NET. I have some Javascript, and I have a submit button with an onClick event.

Is it possible to call a method I created in ASP with Javascript's onClick event?

Hi Ashish,

I suggest the Microsoft AJAX library. Once installed and referenced, you just add a line in your page load or init:

Ajax.Utility.RegisterTypeForAjax(GetType(YOURPAGECLASSNAME))

Then you can do things like:

<Ajax.AjaxMethod()> _

Public Function Get5() AS Integer

Return 5

End Function

Then, you can call it on your page as:

PageClassName.Get5(javascriptCallbackFunction);

The last parameter of your function call must be the javascript callback function that will be executed when the AJAX request is returned.
