This article describes a simple collapsible panel control for ASP.NET. This is a server side control, therefore you can add it to the Visual Studio toolbox and re-use it in your projects.
The collapsible panel extends the WebControl and it provides:
- A designer where users can place other controls inside (using the default ReadWriteControlDesigner).
- The collapsible panel can be nested.
- The panel is draggable (all the JavaScript code related to dragging is provided by Tim Taylor, visit him!).
Some other properties also allow it to be used as a simple yet useful control in your project.
