Question

I am new to UserControls, and while developing my own control I found a problem with showing events of my control in the property grid at design time. If I have some events in my control I want to see them in Property grid and if I double-click that I want to have a handler, in the same way Microsoft does for its controls.

Answer 1

They should automatically appear if I’m not mistaken. Make sure you’ve built your project though, or changes won’t propagate to open designers. And make sure it’s a public event too. (Private/protected events rightfully shouldn’t show up because they’re not accessible.)

One thing you can do to make your user’s design experience nicer is to do something like the following:

    [Description('This event is raised when the user presses the enter key while the control has focus.'),     Category('Key')]     public event EventHandler EnterPressed; 

The ‘description’ bit puts a nice message in the description panel of the property window. The ‘category’ bit puts it in a certain category (the default is Misc. at the end).

By the way, you haven’t specified a language or environment, so the above may need to be modified if it’s not C# in Visual Studio 2005+.
