With ASP.NET, how do I prompt the user for a yes/no question and getting the result back to my .ascx?

So far I can open a confirmation dialog with use of Javascript, but I can't return the value. But I don't know if this is the right approach.

You can use standart JavaScript confirm() function to show popup and do Post Back in case of Yes or No. For example:

if (confirm('Question')) {

    __doPostBack('', 'Yes_clicked');

} else {

    __doPostBack('', 'No_clicked')

}

Then on server in Page_Load() method do:

if (IsPostBack)

{

    var result = Request.Params[__EVENTARGUMENT];

}

You can also do it async by specifying the first parameter of __doPostBack() function as ID of any update panel.
