    <p>In my program I have a listbox that when the user double clicks an object it looks to a switch statement to see what event should occur. As the list begins getting larger I'm curious if there is a way to avoid having to maintain the list of objects in 2 places (once in a list to Add to the listbox, and once in the switch statement. Is there a way to index/read/store the various Cases of my switch statement, then add them as objects to my listbox?</p> <p>Example: (doesn't work, just a theory)</p> <pre><code>Switch (n) ForEach (Case c in Cases) { arrayCases.Add(c); } listbox.Items.AddRange(arrayCases); </code></pre> <p>EDIT:</p> <p>Going on the Dictionary recommendations I now have:</p> <pre><code>public void SetDictionary() { //add entries to the dictionary dict["cat"] = new Action(Cat); dict["dog"] = new Action(Dog); //add each dictionary entry to the listbox. foreach (string key in dict.Keys) { listboxTest.Items.Add(key); } } //when an item in the listbox is double clicked private void listboxTest_DoubleClick(object sender, EventArgs e) { testrun(listboxCases.SelectedItem.ToString()); } public void testrun(string n) { //this is supposed to receive the item that was double clicked in the listbox, and run it's corresponding action as defined in the dictionary. var action = dict[n] as Action action(); } </code></pre> <p>I believe that my code above is mostly correct and that I'm understanding it, however the action line: var action = dict[n] as Action action();</p> <p>Shows an error stating 'action' is expecting a ';'. Is my logic here accurate? If so, why is the action call incorrect?</p>

    3. COI understand what you mean, you want to programmatically generate the cases in your switch, but you actually shouldn't need to do this. There will be another way to do whatever it is you're trying to do such as taking the selected index of the listbox.

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.
