How to give scroll bar to an WPF treeview [closed]

I have used the

<ScrollViewer CanContentScroll="True">
    <TreeView ...>
    </TreeView>
</ScrollViewer>

but not properly working I want a new one

TreeView manages its own scroll viewer. You'll want to set either ScrollViewer.HorizontalScrollBarVisibility or ScrollViewer.VerticalScrollBarVisiblity to Visible on the tree view itself to force the respective scrollbars to display.

<TreeView
  ScrollViewer.VerticalScrollBarVisibility="Visible"
  ScrollViewer.HorizontalScrollBarVisibility="Visible" />

Also, make sure your TreeView doesn't live inside a control that will extend vertically forever - a common mistake is this:

<StackPanel>
   <... />
      <TreeView>

In this example, the TreeView will grow longer and longer without scrolling, because the StackPanel has infinite height.
