using DevExpress.Xpf.RichEdit.Menu;
using DevExpress.XtraRichEdit.Commands;
// ...
private void richTextEditor_PopupMenuShowing(object sender, PopupMenuShowingEventArgs e) {
// Check whether the event is raised for document text.
if (e.MenuType == RichEditMenuType.Text) {
// Create a menu item to insert a picture
// and bind this item to the Rich Text Editor's command.
e.Customizations.Add(new BarButtonItem() {
Command = RichEditUICommand.InsertFloatingPicture,
Content = "Insert Picture",
CommandParameter = richTextEditor
});
// Create a custom menu item to highlight selected text.
var menuItem = new BarButtonItem() {
Name = "highlightSelectionItem",
Content = "Highlight Selection"
};
menuItem.ItemClick += MenuItem_ItemClick; ;
e.Customizations.Add(menuItem);
}
// Remove the "Increase Indent" item from the menu.
e.Customizations.Add(new RemoveRichEditCommandAction() {
Id = RichEditCommandId.IncreaseIndent
});
// Remove the "Decrease Indent" item from the menu.
e.Customizations.Add(new RemoveRichEditCommandAction() {
Id = RichEditCommandId.DecreaseIndent
