WPF left-click Popup Action menu, and Disable right-click menu

In the current version of WPF, many of the controls have a ContextMenu property that can set the component's right-click menu, which is really handy, but sometimes we may need to click the left mouse button to eject the ContextMenu, Instead of right-clicking (that is, when the right mouse button is clicked, the ContextMenu does not pop up), we can easily implement the effect of setting a pop-up menu like in Flex.

1. Add a button with a menu at the front desk, as follows:

<ButtonName= "Btnmenu"Width= " the"Height= "+"Content= "Menu"Initialized= "Btnmenu_initialized">    <Button. ContextMenu>        <ContextMenuName= "ContextMenu">            <MenuItemHeader= "Copy"/>            <MenuItemHeader= "Paste"/>            <MenuItemHeader= "Cut"/>            <MenuItemHeader= "Delete"/>        </ContextMenu>    </Button.contextmenu></Button>

2, in the background, the implementation of initialized= "btnmenu_initialized", initialize the right-click menu is null:

Private void btnmenu_initialized (object  sender, EventArgs e) {     // Set the right-click menu to NULL this     null;}

3. Click the left mouse button pop-up menu, as follows:

Private void Btnmenu_click (object  sender, RoutedEventArgs e) {    // target     This  This . Btnmenu;     // location    this. contextmenu.placement = placementmode.top;     // Show Menu     This true ;}
