    <p>I am attempting to setup a <code>dictionary</code> that will then have its <code>keys</code> stored as <code>items</code> in a <code>listbox</code>. </p> <p>I have been able to establish a <code>dictionary</code> that then has its <code>keys</code> entered in the <code>listbox</code>, but I'm not sure how to then execute the action associated with the <code>key</code>. From the previous thread there was a recommendation, but I've ran into issues with it:<a href="https://stackoverflow.com/questions/14244455/how-to-store-a-list-of-cases-from-switch-statement#comment19766478_14244455"> Original Thread </a> </p> <pre><code>Dictionary&lt;string, Action&gt; dict = new Dictionary&lt;string, Action&gt;(); 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: </p> <pre><code>var action = dict[n] as Action action(); </code></pre> <p>Shows an error stating 'action' is expecting a <code>';'</code>. Is my logic here accurate? If so, why is the action call incorrect?</p>

    2. COFuzz, you sample code missing the most important part - type of dictionary you use (I suspect non-generic one). Please check exact types suggested in original answers.

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.
