Description

With this KB article, we will demonstrate how to customize the context menu that appears when right-clicking on DocumentWindow tabs in RadDock. The goal is to replace the default RadDock context menu with a custom menu containing options such as "Add," "Close," "Lock" and "Edit". The Edit menu option triggers inline editing of the tab name.

Solution

Use the built-in ContextMenuService to customize the context menu for DocumentWindow tabs in RadDock. Follow these steps:

1. Subscribe to the ContextMenuDisplaying event from the ContextMenuService.
2. Clear the default menu items and add custom ones.
3. Enable inline editing by calling the BeginEdit() method on the TabStripElement associated with the clicked tab.

Here is the complete implementation:

C#

public Form1()
{
    InitializeComponent();
    // Enable inline editing for the DocumentTabStrip
    documentTabStrip2.TabStripElement.AllowEdit = true;
    // Subscribe to the ContextMenuDisplaying event
    this.radDock1.GetService<ContextMenuService>().ContextMenuDisplaying += RadDock_ContextMenuDisplaying;
}

private void RadDock_ContextMenuDisplaying(object sender, ContextMenuDisplayingEventArgs e)
{
    // Check if the context menu is for a DocumentWindow tab
    if (e.DockWindow is DocumentWindow)
    {
        // Clear default menu items
        e.MenuItems.Clear();

        // Add custom menu items
        e.MenuItems.Add(new RadMenuItem("Add"));
        e.MenuItems.Add(new RadMenuItem("Close"));
        e.MenuItems.Add(new RadMenuItem("Lock"));

        // Add "Edit" menu item and attach edit action
        RadMenuItem editItem = new RadMenuItem("Edit");
        editItem.Click += (s, args) =>
        {
            var window = (DocumentWindow)e.DockWindow;
            window.DockTabStrip.TabStripElement.BeginEdit();
        };
        e.MenuItems.Add(editItem);
    }
}
