Question

I am working on asp.net, addon with JQuery.

After registering endRequest inside ready() function of Jquery.

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

For the function:

function EndRequestHandler(sender,
args) {}

How could I retrieve the ID of the button where I click based on ‘sender’ and ‘args’?

Thanks in advance.

Answer 1

This should do it.

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

function EndRequestHandler(sender, args) {
    if (args.get_error() == undefined) {
        alert(sender._postBackSettings.sourceElement.id);            
    }
}
