Xamarin C# - Android - Prevent an AlertDialog from closing on PositiveButton click

To prevent an AlertDialog from closing on PositiveButton click in Xamarin.Android, you can override the OnClick method of the positive button and set the Dialog property to null. Here's an example:

AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.SetTitle("Dialog Title"); builder.SetMessage("Dialog Message"); builder.SetPositiveButton("OK", (sender, args) => { // Do something here // To prevent the dialog from closing, set the Dialog property to null ((AlertDialog)sender).Dialog = null; }); AlertDialog dialog = builder.Create(); dialog.Show();

In this example, we create a new AlertDialog using the AlertDialog.Builder class. We set the title, message, and positive button text using the various builder methods.

When the user clicks the positive button, we override the OnClick method using a lambda expression. Inside the method, we do whatever action we want to perform, and then we set the Dialog property of the AlertDialog to null. This prevents the dialog from closing when the positive button is clicked.

Note that if you want to close the dialog programmatically after performing your action, you can do so by calling the Dismiss method of the AlertDialog object.
