Custom Menu

The CPDFView supports a right-click menu feature. Right-clicking within the CPDFView area will trigger a custom menu.

You can set different custom menus for users in various contexts. For instance, setting the page zoom level when right-clicking in a blank area, enabling copy options when right-clicking on text, images, or annotations, etc.

The steps for setting up a custom menu are as follows:

1. Register for the custom menu event.
2. Create a context menu on CPDFViewerTool and add menu items (Copy, Cut, Paste, Delete).

This example shows how to create a custom menu:

// Register custom menu event
toolManager.MouseRightButtonDownHandler += ToolManager_MouseRightButtonDownHandler;

 private void ToolManager_MouseRightButtonDownHandler(object sender, MouseEventObject e)
 {
     // Create a context menu on CPDFViewerTool and add menu items (Copy, Cut, Paste, Delete).
     ContextMenu contextMenu = new ContextMenu();
     contextMenu.Items.Add(new MenuItem() { Header = "Copy", Command = ApplicationCommands.Copy, CommandTarget = (UIElement)sender });
     contextMenu.Items.Add(new MenuItem() { Header = "Cut", Command = ApplicationCommands.Cut, CommandTarget = (UIElement)sender });
     contextMenu.Items.Add(new MenuItem() { Header = "Paste", Command = ApplicationCommands.Paste, CommandTarget = (UIElement)sender });
     contextMenu.Items.Add(new MenuItem() { Header = "Delete", Command = ApplicationCommands.Delete, CommandTarget = (UIElement)sender });

     CPDFViewerTool tool = sender as CPDFViewerTool;
     tool.ContextMenu = contextMenu;
 }
