Getting TreeViewItem for the selected item in a TreeView

Question

I have a TreeView that is bound to a dataset which is having parent child relation. How i will get seleted TreeViewItem from the TreeView? Please help me. My code is below.

Answer 1

The best solution I've found involves a simple helper method and can be used in virtually any of the TreeView's events (i.e., SelectedItemChanged, MouseLeftButtonUp, etc.).

TreeViewItem Item = TreeViewHelper.VisualUpwardSearch(e.OriginalSource as DependencyObject);

I am using multiple hierarchy data templates and this is the only method that worked for me. Now, I'm able to create a new control based on TreeView and can handle all events involving the selected item internally.

public static TreeViewItem VisualUpwardSearch(DependencyObject source)
{
    while (source != null && !(source is TreeViewItem)) source = System.Windows.Media.VisualTreeHelper.GetParent(source);
    return source as TreeViewItem;
}
