    <p>I have several <code>Control</code> such as <code>ToolStripMenuItem</code> and <code>Button</code> that need to have a function bound to their click event. They will either generate a new <code>Form</code> or add a <code>TabPage</code> to a current <code>TabControl</code>. I may end up having several different <code>Control</code> that will need the same function, so I thought of making a Global function repository.</p> <p>I would have a class named <code>Services</code> looking like this:</p> <pre><code>public class Services { TabControl container; delegate void fonction(int id); Dictionary&lt;string, fonction&gt; functions = new Dictionary&lt;string, fonction&gt;(); public Services(TabControl control) { container = control; InitFunctions(); } public Delegate Getfunction(string name) { if (functions.ContainsKey(name)) return functions[name]; else throw new NotImplementedException("Failed to instantiate " + name ); } // List of all the desired functions // Function example private void ProductLoan(int id) { string name = "Loan"+id.ToString(); Form newForm = new Loan(); newForm.Text = Properties.Resources.MakeLoan; newForm.ShowDialog(); } private void InitFunctions() { fonction f = new fonction(ProductLoan); functions.Add("Loan", f); // For each functions // f = new fonction(name); // functions.Add(name, f); } } </code></pre> <p>This class would be instantiated when the program start and stored globally so it can be accessed everywhere. <strong>Correct me if I am wrong to proceed like this, but I didn't make the <code>Services</code> class static since it needs to have an instance of the <code>TabControl</code> and to initialise the function list.</strong></p> <p>I have no clue if this is a good idea so I would appreciate some advice.</p>

    1. COYou could make static assign `TabControl` once, at the load. I prefer static members to do "generic things"

    2. COInteresting, but I would still need to initialise the function list. The `Services` class could be satic though, since no parameters are required. My only concern is that any programmer could try to get a function even if he didn't assign the TabControl. I wanna make sure the only way to use `Services` is when it has the TabControl instance/reference AND the function list initialised.

    3. COI have edited your title. Please see, "[Should questions include “tags” in their titles?](http://meta.stackexchange.com/questions/19190/)", where the consensus is "no, they should not".

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.
