c# - Document.Ready() is not working after PostBack

Question

I have a page that contains a user control within an update panel. $(document).ready(function() ) { is called and executes the code correctly when the page firsts loads but if the user clicks a button (within the user control), the document.ready() doesn't get called (document.load, onload also don't work)

I have researched this on the net and found similar problems but nothing that can explain why this isn't working. What other causes can there be for document.ready not working?

Answer 1

This will be a problem with partial postback. The DOM isn't reloaded and so the document ready function won't be hit again. You need to assign a partial postback handler in JavaScript like so...

function doSomething() {
   //whatever you want to do on partial postback
}

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(doSomething);

The above call to add_endRequest should be placed in the JavaScript which is executed when the page first loads.
