Bind zweite UITableView auf RowClick des ersten UITableView in der gleichen UIViewController - IOS Xamarin

Question

Ich habe zwei UITableView in der gleichen UIViewController. tblView1 & tblView2.

Beide TableViews bringen Daten dynamisch. Jetzt ist mein Problem: Ich möchte Daten in tblView2 auf der Grundlage von SelectedRow von tblView1 laden.

Zum Beispiel, wenn ich einen Firmennamen aus tblView1 auswähle, dann muss tblView2 die Autos dieser Firma füllen.

Ich habe rowIndex meiner ersten Tabelle (tblView1), aber ich kann meine tblView2 nicht von der RowSelected-Methode von tblView1 binden. Ich brauche Hilfe bei der Bindung meines tblView2. Wie kann ich das tun?
