Adding TabItem at runtime in a C# WPF application

In this article we will be creating certain tabs in a tab control with context menu with an option to remove certain tab item.

First create a blank c# WPF application using visual studio 2008 and name the default grid as Master.

Right click on window and select view code,

Here we create a method to remove a tabItem. The method accepts a TabItem needed to be removed as parameter.

private void closeTabItem(TabItem item)

        if (item != null)

            // find the parent tab control

            TabControl tabControl = item.Parent as TabControl;

            if (tabControl != null)

                tabControl.Items.Remove(item); // remove tabItem

Now Double click the window and add this code to window load event.

       // Create Context Menu

        ContextMenu contextMenu1;

        contextMenu1 = new ContextMenu();

        //Create menu items

        MenuItem menuItem1;

        menuItem1 = new MenuItem();

        //add menu item in context menu

        contextMenu1.Items.Add(menuItem1);

        menuItem1.Header = "Close"; // define name of context menu

        //Create Tab Items

        TabItem Item1 = new TabItem();

        Item1.Header = "Tab1";

        TabItem Item2 = new TabItem();

        Item2.Header = "Tab2";

        // define clicking event of menuitem

        menuItem1.Click += delegate { closeTabItem(Item1); };

        // Incorporate context menu with tab items

        Item1.ContextMenu = contextMenu1;

        //Create tab Control

        TabControl tabControl1 = new TabControl();

        //Insert Tab Items in Tab Control

        tabControl1.Items.Add(Item1);

        tabControl1.Items.Add(Item2);

        Master.Childer.Add(tabControl1); // Insert Tab Control in Master Grid

Now Compile and execute the project. On right click on Tab1 you will see a pop-up menu with close option to close (remove) that tabItem.
