Prevent Automatic Horizontal Scroll in TreeView

Whenever a node is selected in my treeview, it automatically does a horizontal scroll to that item. Is there a way to disable this?

Solution

  • Handle the RequestBringIntoView event and set Handled to true, and the framework won't try to bring the item into view. For example, do something like this in your XAML: 

    <TreeView>
    <TreeView.ItemContainerStyle>
        <Style TargetType="TreeViewItem">
            <EventSetter Event="RequestBringIntoView" Handler="TreeViewItem_RequestBringIntoView"/>
        </Style>
    </TreeView.ItemContainerStyle>
</TreeView>

    And then this in your code-behind: 

    private void TreeViewItem_RequestBringIntoView(object sender, RequestBringIntoViewEventArgs e)
{
    e.Handled = true;
}
