copied!<p>The <code>myName</code> property you are using changes the <code>name</code> private field of myLes instance and not the name private field of myEv instance created in the ItemSend_Click.</p> <p>In an Object Oriented Language when you create an instance of a class, that instance has a copy of every non-static private/public variable declared in the class. So when you write</p> <pre><code> Leisure myLes = new Leisure(); </code></pre> <p>you are creating an instance of Leisure class, but this instance, while inherithing from Events has a different set of internal variables and not the same variables of the current Event instance (myEv).</p> <p>Looking at your code I suggest to create a third class called</p> <pre><code>public class EventFactory { public Event CreateEvent(string eventType, string eventName) { switch(enventType) { case "Leisure": Leisure myLes = new Leisure(); myLes.eventNames(eventName); return myLes; // case Add other specialized events here: // break; default: return null; } } } </code></pre> <p>change your Events class removing the inheritance from Form1 (not needed as far as I can tell) and the method myEvent</p> <p>now your ItemSend_Click could be written in this way</p> <pre><code>private void itemSend_Click(object sender, EventArgs e) { Events myEv = new EventFactory().CreateEvent(eventType, itemInput.Text); formEventName = myEv.myName; txtOutput.Text = "Event name is " + formEventName + "\r\n"; } </code></pre> <p>this works because <code>Leisure</code> derives from <code>Events</code> and you could treat every Leisure instance as an Event instance.</p>
