Xamarin.Forms provides support for modal pages. A modal page encourages users to complete a self-contained task that cannot be navigated away from until the task is completed or cancelled.
They are different types of pop up.
- Action Sheets
- Modal Page Pop Up
We can display an alert using
DisplayAlert method on the Page
DisplayAlert ("Alert", "You have been alerted", "OK");
We can get the result from the alert by assign the return to a variable
var result = DisplayAlert ("Delete", "Delete file", "OK", "Cancel");
Action Sheets let the user choose from a list of options. To display the action sheets we use
var action = await DisplayActionSheet ("ActionSheet: Send to?", "Cancel", null, "Email", "Twitter", "Facebook");
The destroy button is rendered differently than the others, and can be left null or specified as the third string parameter.
