jQuery Plugin to Register a Function to Run on UpdatePanel Request

Short post, long title. Here is a simple jQuery plugin that makes it a little easier to add an begin/end request handler to the PageRequestManager on an ASP.NET web form.

registerAsync Source:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

(function ($, undefined) {     $.registerAsyncBegin = function(callback) {         var prm = Sys.WebForms.PageRequestManager.getInstance();         if (prm) {             prm.add_beginRequest(callback);         }         return callback;     };     $.registerAsyncEnd = function(callback) {         var prm = Sys.WebForms.PageRequestManager.getInstance();         if (prm) {             prm.add_endRequest(callback);         }         return callback;     }; })(jQuery);

This example adds a function to be executed after ever Update Panel request and runs the function. This is useful if you have a function that needs to do some initial processing as well as after a request.

Example:

1	($.registerAsyncEnd(SomeCallbackFunction))();
