This example demonstrates how to add a custom bar button item to the popup menu.
To add a new item to a popup menu shown for the navigation pane of a PDF Viewer, handle the PdfViewer.PopupMenuShowing event and then use the PdfPopupMenuShowingEventArgs.ItemLinks property.
using System.Windows.Forms;
using DevExpress.XtraPdfViewer;
using DevExpress.XtraBars;
namespace CustomPopupMenu {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
pdfViewer1.LoadDocument("..\\..\\Demo.pdf");
}
void pdfViewer1_PopupMenuShowing(object sender, PdfPopupMenuShowingEventArgs e) {
// Create a bar button item.
BarButtonItem browseBarButton = new BarButtonItem();
browseBarButton.Caption = "Custom Item";
// Insert the bar buttom item into the PDF Viewer popup menu and start a new group.
e.ItemLinks.Add(browseBarButton, true);
// Handle the bar button click event.
browseBarButton.ItemClick += browseBarButton_ItemClick;
}
void browseBarButton_ItemClick(object sender, ItemClickEventArgs e) {
MessageBox.Show("ItemClick event fires");
}
}
}
