I have used events in the past extensively when developing windows applications. I just discovered a new feature recently when developing a windows workflow application. The ability to execute Code when Host Programs Add\Remove\Raise Events in your custom control\object.

I have developed a sample project to demonstrate the custom event feature. When you run the solution click on the "Add Handler" and "Remove Handler" buttons, you will see custom code getting invoked. One needs to be familiar with the base windows event\delegate model before your understand what is happening here to appreciate it fully. 

Download CustomEvents.zip, unzip it and run the solution.

If your .NET solution contains projects that contain custom/user controls for windows/web forms these controls are automatically loaded into the toolbox so that they can be utilized on your forms. In some cases when there are a large number of controls in your project the solution seems to compile slowly or the toolbox seems to take quite some time to load. If you are facing such issues turn off the AutoToolboxPopulate property on the ToolsàOptionsàWindows Forms DesigneràGeneral tab.

I have uploaded the Mirosoft Reston Code Camp presentation and source code for my talk on custom controls (with data binding) at http://www.knowthycode.com/Downloads/20060608/WinForms_Custom_Controls_Presentation_Clyde.zip
