Setting dialog button clicklistener in Android Xamarin

Question

I want to display a dialog alert in my Xamarin Android app (C#), and I want to do stuff to the dialog when I click on the buttons.

From before, I use this code:

AlertDialog.Builder builder = new AlertDialog.Builder(this)
    .SetTitle("Delete")
    .SetMessage("Are you sure you want to delete?)
    .SetPositiveButton("No", (senderAlert, args) => { })
    .SetNegativeButton("Yes", (senderAlert, args) => {
    DatabaseHelper.Delete(item);
});
builder.Create().Show();

To make a random example, lets say I want to keep the dialog box open until the item is deleted, but I want to disable the Yes button and change the message text while Android is working. Is this possible from the code I have to access the dialog and change it? Neither senderAlert nor args have any useful properties or methods.

I have been looking for other ways to build my dialog, and I have seen these two:

1) This guy is using the way bellow, but my DialogInterface does not have a .OnClickListener()

builder.setPositiveButton("Test", 
new DialogInterface.OnClickListener()
{
    @Override
    public void onClick(DialogInterface dialog, int which)
    {
        //Do stuff to dialog
    }
});

2) This guy is using IDialogInterfaceOnClickListener, and I have been trying to find an example of how to do it this way, but I havent found any. Seems like he is using null instead of the code I would want.

.setPositiveButton("OK", (Android.Content.IDialogInterfaceOnClickListener)null)

Any ideas?

I use something like this:

      using (var builder = new AlertDialog.Builder(Activity))
      {
         var title = "Please edit your details:";
         builder.SetTitle(title);
         builder.SetPositiveButton("OK", OkAction);
         builder.SetNegativeButton("Cancel", CancelAction);
         var myCustomDialog = builder.Create();

         myCustomDialog.Show();
      }

      private void OkAction(object sender, DialogClickEventArgs e)
      {
         var myButton = sender as Button; //this will give you the OK button on the dialog but you're already in here so you don't really need it - just perform the action you want to do directly unless I'm missing something..
         if(myButton != null)
         {
             //do something on ok selected
         }
      }
      private void CancelAction(object sender, DialogClickEventArgs e)
      {
         //do something on cancel selected
      }
