I use the Devexpresss20 treelist control, in the main window treelist contextMenuStrip right can be normal open,
In the main window opens a new window, the mainwindow calls child window, also has a treelist contextMenuStrip in the child window, right-click but there was no way to start contextMenuStrip, every other child window of the gridview can start normal right contextMenuStrip menu
Each ace to give directions, next is a small white, light spray,
