You can use the
MessageDialog class to Represents a dialog.
public sealed class MessageDialog : Object
If you don't specify any commands, then a default command is added to close the dialog.
Sample
private async void testButton_Click(object sender, RoutedEventArgs e)
{
// Create the message dialog and set its content
var messageDialog = new MessageDialog("No internet connection has been found.");
// Show the message dialog
await messageDialog.ShowAsync();
}
Result:
You want to add custom commands by Commands.Add.
Sample
private async void testButton_Click(object sender, RoutedEventArgs e)
{
// Create the message dialog and set its content
var messageDialog = new MessageDialog("No internet connection has been found.");
// Add commands and set their callbacks; both buttons
// use the same callback function instead of inline event handlers
messageDialog.Commands.Add(new UICommand("Try again",
new UICommandInvokedHandler(this.doTryAgain)));
messageDialog.Commands.Add(new UICommand("Close",
new UICommandInvokedHandler(this.doClose)));
// Set the command that will be invoked by default
messageDialog.DefaultCommandIndex = 0;
// Set the command to be invoked when escape is pressed
messageDialog.CancelCommandIndex = 1;
// Show the message dialog
await messageDialog.ShowAsync();
}
private void doTryAgain(IUICommand command)
{
// do something
}
private void doClose(IUICommand command)
{
// do something
}
Result:
