Wpf Tabcontrol Contextmenu

This sample demonstrates how to configure context menus for tab items in Syncfusion TabControlExt in a WPF application. The TabControlExt control provides built-in context menu support and allows customization of menu items for individual tabs.

Features in This Sample

• Built-in Context Menu: Enable or disable default context menu options for tab items and tab list.
• Custom Context Menu Items: Add custom menu items and sub-items to tab headers.
• MVVM Support: Bind context menu visibility and customization options to properties in the ViewModel.
• Nested Menu Items: Create hierarchical context menus with multiple levels.

Key Properties Used

• ShowTabItemContextMenu: Shows or hides the context menu for tab items.
• ShowTabListContextMenu: Shows or hides the context menu for the tab list.
• IsCustomTabItemContextMenuEnabled: Enables custom context menu items for tab items.
• DefaultContextMenuItemVisibility: Controls visibility of default context menu items (Visible or Collapsed).

XAML Overview

<syncfusion:TabControlExt ShowTabItemContextMenu="{Binding ShowTabItemContextMenu}"
                          ShowTabListContextMenu="{Binding ShowTabListContextMenu}"
                          IsCustomTabItemContextMenuEnabled="{Binding IsCustomTabItemContextMenuEnabled}"
                          DefaultContextMenuItemVisibility="{Binding DefaultContextMenuItemVisibility}">
    <syncfusion:TabItemExt Header="tabItem1">
        <syncfusion:TabItemExt.Content>
            <TextBlock Text="This is the first tab item content" />
        </syncfusion:TabItemExt.Content>
        <syncfusion:TabItemExt.ContextMenuItems>
            <syncfusion:CustomMenuItem Header="Edit">
                <syncfusion:CustomMenuItem Header="SubItem0" />
                <syncfusion:CustomMenuItem Header="SubItem1" />
                <syncfusion:CustomMenuItem Header="SubItem2">
                    <syncfusion:CustomMenuItem Header="Level 2" />
                </syncfusion:CustomMenuItem>
            </syncfusion:CustomMenuItem>
            <syncfusion:CustomMenuItem Header="Copy" />
            <syncfusion:CustomMenuItem Header="Paste" />
        </syncfusion:TabItemExt.ContextMenuItems>
    </syncfusion:TabItemExt>
</syncfusion:TabControlExt>

How It Works

1. The ViewModel exposes properties like ShowTabItemContextMenu, ShowTabListContextMenu, and IsCustomTabItemContextMenuEnabled.
2. These properties are bound to the TabControlExt to dynamically control context menu behavior.
3. Custom context menu items are defined inside each TabItemExt using CustomMenuItem elements.
