Question

I am using an asp.net update panel to refresh the content on a page when a menu item is selected.

Within the content that is updated are images which have a javascript reflection function which is triggered with the following line of code:

window.onload = function () { addReflections(); }

This runs fine when the page is first loaded but not when a menu item is selected and the update panel is run.

On previous projects using jquery code I have replaced document.ready with function pageLoad but there is no document.ready on this page.

Basically, it’s because that event isn’t triggered by an update panel refresh.

There are ways to achieve this behaviour though, Ajax.Net has an EndRequestHandler function that you can hook into.

Here’s a good example:
