Create a Treeview in WPF

Step 1: Create an empty WPF using Visual Studio, enter the name for the application and click on OK



Step 2: Drag and drop the TreeViewItem.



Code:

<TreeViewItem Header="Developer" Tag="Group" >
<TreeViewItem Header="Romil" />
<TreeViewItem Header="Prabhjot" />
<TreeViewItem Header="Feroz" />
<TreeViewItem Header="Shyamal" />
<TreeViewItem Header="Tester" Tag="Group" >
<TreeViewItem Header="Suketu" />
<TreeViewItem Header="Monali" />
<TreeViewItem Header="Ayushi" />
<TreeViewItem Header="Mathan" />
</TreeViewItem>
</TreeViewItem>

The complete page of MainWindow.xaml will be like:

<Window x:Class="Treeview_wpf.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TreeViewItem Header="Developer" Tag="Group">
            <TreeViewItem Header="Romil" />
            <TreeViewItem Header="Prabhjot" />
            <TreeViewItem Header="Feroz" />
            <TreeViewItem Header="Shyamal" />
            <TreeViewItem Header="Tester" Tag="Group">
                <TreeViewItem Header="Suketu" />
                <TreeViewItem Header="Monali" />
                <TreeViewItem Header="Ayushi" />
                <TreeViewItem Header="Mathan" />
            </TreeViewItem>
        </TreeViewItem>

    </Grid>
</Window>

Step 3: Now run the code.
