Introduction To call server side events and functions from client side javascript function in asp.net. Suppose we want to perform both client side and server side activities for an event,we can use this logic Background Three are 2 ways to acheive this functionality. one using __dopostback() and another using form.submit(). Say you are having a client side javascript function named clientfunction. From clientfunction if u want to call any serverside function or serverside event(eg: dropdown selected index change) say server function and serverdropdown. The code Code: function clientfunction { //do the client side validations here // //now call the server side dropdown event explicitly __doPostBack('cboserverdropdown',''); } Code: function clientfunction { //do the client side validations here // //or just give below code form.submit(); }
I am looking for the way to do this in classic asp 3.0 language. If you know how to do it then please post article for that too. By the way this article is good.
