RadWindow.Alert - sound?

[Jeff]

I'm replacing some calls to MessageBox.Show() with calls to RadWindow.Alert so that the message dialogs match the theme of my application.  However, I noticed that the Alert dialog doesn't play any sort of system sound like MessageBox.Show.  Digging through the docs and the forum, I don't see any mention of this.  I'd definitely think the pre-defined dialogs should have some built-in system sound support., right?

Input appreciated.

Hi Jeff,

You can easily add sound to RadWindow.Alert dialog by using Opened event handler:

private MediaPlayer player;

private void RadButton_Click(object sender, RoutedEventArgs e)
{

    var dialogParams = new DialogParameters();
    dialogParams.Opened = Opened;
    dialogParams.Closed = AlertClosed;
    dialogParams.Content = "Content";
    RadWindow.Alert(dialogParams);
}

private void AlertClosed(object sender, WindowClosedEventArgs e)
{
    this.player.Stop();
}

private void Opened(object sender, EventArgs e)
{
    this.PlaySound();
}

private void PlaySound()
{
    Uri uri = new Uri("../../MyWave.wav", UriKind.RelativeOrAbsolute);
    if (this.player == null)
    {
        this.player = new MediaPlayer();
        this.player.Open(uri);
    }

    this.player.Play();
}

The idea of code above is to play the wave when RadWindow.Alert is opened and stop it when the alert is closed.

Hope this helps.

Thanks for the sample code.  While it (or something similar) may very well be the best solution to my problem, I want to make sure I was clear about the issue.

As mentioned above, I'm replacing MessageBox.Show() calls with RadWindow.Alert() calls in order to get proper themeing.  However, I immediately noticed that when a RadWindow.Alert is opened (in place of an Error or Warning style MessageBox), that it's "silent".  That is, it doesn't play the standard Windows sounds normally associated with the various MessageBox styles.

That strikes me as odd as I presume replacing MessageBox.Show calls is a typical use-case for RadWindow.Alert, right?  I assumed that I had somehow missed some built-in mechanism to play standard system sounds via RadWindow.Alert, but maybe that's not the case?

Based on the above, is the sample code still my best route?  If so, I guess I'll just need to wrap this all up into a reusable component to better mimic a typical MessageBox.

Assuming there is no "built-in" support for playing standard system sounds, might you consider that for a future enhancement, as it seems like a natural fit.

Thanks,

Jeff

So, with some additional research, it looks like I can do what I want using something like this:

RadWindow.Alert(new DialogParameters()
{
    Content = new System.Windows.Controls.TextBlock {
        Text = ex.Message, Width = 250, TextWrapping = TextWrapping.Wrap },
    Header = "Update Error",
    Opened = (alertDialog, eventArgs) => System.Media.SystemSounds.Exclamation.Play()
});

That'll work, but it would be nice if some of the default dialogs had built-in system sound support.

Thanks,

Jeff
