How to do it...

Let's create the UI interface to host a very basic tab control with a few tab items inside it. Perform the following steps:

1. From the Solution Explorer window, open the MainWindow.xaml file.
2. Inside the default Grid panel, add the TabControl with two TabItem controls as shown in the following code:

<Grid> 
    <TabControl> 
        <TabItem Header="Tab 1"> 
            <TextBlock Text="You have selected 'Tab 1'" 
             FontSize="30" Margin="4"/> 
        </TabItem> 
        <TabItem Header="Tab 2"> 
            <TextBlock Text="You have selected 'Tab 2'" 
             FontSize="30" Margin="4"/> 
        </TabItem> 
    </TabControl> 
</Grid>

3. Now run this application and you will see the following UI, which contains two tabs inside it:
   
4. Close the application and return to the XAML editor to add another...
