    <p>I'm wondering as to why my private variable 'name' within my Events class won't change when I access the property from my Leisure class which inherits from Events. I need Leisure to use the properties to change it, and then in my form class, it should be able to read the value of 'name' from events. See below:</p> <pre><code>public partial class Form1 : Form //Main form class { private string eventType; //used for event type selection private string formEventName; //used to store selected event name private void itemSend_Click(object sender, EventArgs e) { //encapsulation Events myEv = new Events(); string name=itemInput.Text; myEv.myEvent(eventType, name); formEventName = myEv.myName; txtOutput.Text = "Event name is " + formEventName + "\r\n"; } class Events:Form1 { private string name; //private variable for event name public string myName //used to change property value depending on what eveny type/ event name { get { return name; } set { name = value; } } public void myEvent(string eventType, string eventName) //variable recieved from main form class { if (eventType == "Leisure") { Leisure myLes = new Leisure(); myLes.eventNames(eventName); } else { //test for other event types } } class Leisure:Events { public void eventNames(string eventName) { //when adding new items add one with a capital and one without myEventNames.Add("music"); myEventNames.Add("Music"); if (myEventNames.Contains(eventName)) { myName = eventName; } else { MessageBox.Show("item not found, please try again"); //error message } } } </code></pre>

    3. COHonestly, the design at a high level troubles me. These forms almost certainly shouldn't be inheriting from each other. You're confusing yourself because you think you're having access to the methods of all of the parents, but you're not actually interacting with your parents because those methods aren't being called on the proper instances. Inheritance isn't the proper way for these forms to communicate.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
