C＃中的自定义用户控件…右键单击菜单以复制文本（Java开发人员学习C＃）

Question

I'm working on a custom user control that essentially displays a name value pair (name is on a black background, value on a white). I have my control displaying correctly, even showing up in Designer and on my build page.

What I'd like to do from here is have the ability to right click on the user control and have a menu come up that has a "Copy Value" option, that when selected will copy the value in the "value" part of the user control to the clipboard. What is the best method of approach?

I'm not sure where to start since most of the documentation on user controls I've found deals with displaying the control, not necessarily interacting with it. Additionally, since I'm still learning C#, I might have left out an important part of my problem in this question, so please point that out if it's the case.

I'm using Visual Studio 2008 (if that matters).

Answer 1

Examine the ContextMenu control and the ContextMenu property of other controls. By assigning a ContextMenu control to the ContextMeny property of another control, you will have the right-click->popup menu wiring done for you. Then you only need to implement the click event of the different menu items in the context menu.

Then you can use the Clipboard.SetText (as suggested by BFree) to set the desired value to the clipboard.

Answer 2

Add a ContextMenu to the control. The, hook into the MouseClick (or MouseDown, whichever works better) event and if it's a Right-Click, then call show on the ContextMenu (there are a few overloads, try to mess with them see which works best for you). Then, in the click event of your context menu, just call Clipboard.SetText(...) to set the value to the clipboard.
