C #/VB. NET: Right-click the source control of the pop-up menu (from which the control is popped up)

Sometimes, to improve performance and save resources, we specify the same right-click/pop-up menu for multiple controls. In this case, a requirement is usually generated: determine the control from which the pop-up menu is popped up, that is, "which control is triggered by right-click", to facilitate further control.

In. net, the implementation is very simple. If the pop-up menu is contextmenustrip1, you only need to judge and process the opening event of the menu.

Private VoidContextmenustripappsopening (ObjectSender, canceleventargs e ){// Obtain the name of the source controlMessageBox. Show (senderAsContextmenustrip). sourcecontrol. Name );}
