I have a button which opens a pop-up window and an Ajax update panel. Inside that window I have another button.
What code do I have to run if I want that update panel to be refreshed, when I press the button from the parent page, without refreshing the whole page?
I sow this code on a web which refreshes the page:
<div id="Container" onclick="__doPostBack('UpdatePanel1', '');">
I am such a good friend with Java.
You need to utilize window.opener object.
window.opener.document.getElementById('Container').onclick();
I'd suggest using jQuery to ensure cross-browser compatibility. And also adding some null-checks of course.
