If you’ve ever used the AJAX Controll Toolkit’s asyncFileUpload control you will undoubtedly have run into some screwiness dealing with how this event does not act like normal update panel async-postbacks. The thing to keep in mind with this control is that it is posting to a hidden iFrame on the page to get around the fact that files cannot be uploaded via the XHR object.
To run client side JS after this event (aside from using the OnClientUploadComplete which doesn’t have much functionality) you can use the Page.ClientScript.RegisterStartupScript method, however this has a huge gotcha. Remember how this event is posted to an iframe. To access the DOM of the actual page (not the iFrame) simply prefix your javascript calls with ‘window.parent’ (such as window.parent.$(‘body’).css(‘background-color’, ‘green’); ).
