Container control adding properties to children

[ballisticnylon]

Hi there everybody,

Today I was playing around with the Flow Layout Panel control (it's a panel that governs the layout of the controls it contains, moving their locations so controls don't overlap). Anyway, any control that is added to a Flow Layout Panel gets a new property, FlowBreak. I've noticed that this property is settable in the Property Grid in the designer, but not in code. I guess my (very general) question is, what's going on here? How does a parent control add a property to its' children, is it a real property that belongs to the child, and finally (and most importantly) how can I write a container control that does the same thing?

Thanks in advance, people. This stuff is confusing.

IExtenderProvider

The IExtenderProvider interface allows properties to be added to existing controls. The following post demonstrates how this can be used to add an ImageIndex property to MenuItem components, which is then used to associate an icon with the menu item.

Extend your Menus with IExtenderProvider

Good luck
