Assyncronous interaction using Sys WebForms PageRequestManager

Question

I'm trying to display a panel to the user when an asynchronous call is made, but only if that happend from a specific call.

using the normal "get control" script I have mine like:

function pageLoad() {

    try {
        var manager = Sys.WebForms.PageRequestManager.getInstance();
        manager.add_endRequest(OnEndRequest);
        manager.add_beginRequest(OnBeginRequest);
    }
    catch (err) { }
}

function OnBeginRequest(sender, args) {
    //alert('Start\n\n' + sender + '\n\n' + args);
    var p = document.getElementById('ajaxLoadingPanel');
    p.style.visibility = 'visible';
    p.style.display = 'inline';
}

function OnEndRequest(sender, args) {
    //alert('End\n\n' + sender + '\n\n' + args); 
    var p = document.getElementById('ajaxLoadingPanel');
    p.style.visibility = 'hidden';
    p.style.display = 'none';
}

but my question is How do I know the methods of sender and args?

I went through the MSDN and they talk nothing about the methods we can use, and there is no intellisence in VS2008 for this part...

any ideas? I want to get a list of methods and properties for both sender and args that I can use of this javascript API.

This documentation is helpful: http://msdn.microsoft.com/en-us/library/bb398976.aspx

It has a table of all the events on PageRequestManager and what their event args are. Then the event args documents their properties, etc. The sender is always the PageRequestManager.

Debug in ScriptDebugger and find out the contents of sender and args you can identify that which control has caused the postback

To know which element caused postback, you can use args.get_postBackElement().id.
