Silverlight 4: The Preceding Departure

Is there a way to capture the close event of a browser in Silverlight application? I have implemented the following code in my .aspx page:

function confirmClose() {
    return "Any message here will prompt a dialog box \n" +
            "before closing the window.";
}

window.onbeforeunload = confirmClose;

When this function is triggered, a popup window with OK and CANCEL buttons will appear.

Is it possible to retrieve the value of what the user clicks either in Silverlight or on the server side?

Appreciate any help. Thank you.

Answer №1

I'm not entirely certain I grasp the gist of your query, it seems like you're working with javascript. However, your focus is on silverlight. Anyways...

The easiest method is to use Html Confirm either within silverlight:

bool result = System.Windows.Browser.HtmlPage.Window.Confirm("Really..?");

or in regular JavaScript:

var result = window.Confirm("Really...?");

To transmit the value to the server, you can save the value in a hidden text field and send it to the server.

Answer №2

Ever thought about using MessageBox in your code? Here's an example of how you can implement it:

MessageBoxResult response =  MessageBox.Show("Text","Title",MessageBoxButton.OKCancel);
if (response == MessageBoxResult.OK)
{

}
else if (response == MessageBoxResult.No)
{

}

By incorporating this, you'll have a convenient popup window with options for OK and Cancel, making it simple to determine the user's selection.

Answer №3

This answer mirrors my previous response to your query about window.close.

If the user clicks Cancel, there will be no action taken. However, selecting OK will trigger the execution of your Application_Exit function.
