# Binding to a Database

The following tutorial demonstrates binding **RadTreeView** to an Access Data Source containing hierarchical data. The table contains columns for "ItemID", "ParentID" and "Name". "Name" is used to populate the text of each node while "ItemID" and "ParentID" describe the hierarchy. The screenshot below shows the appearance of the running example application.

1. In a new AJAX-Enabled Web Application, drop a **RadTreeView** to the default form.

2. Locate the "Database.mdb" Access Data Base in the **RadControls for ASP.NET AJAX** suite version installation directory under *\Live Demos\App_Data*. The typical path would be similar to this one: *\Telerik\RadControls for ASPNET <current version>\Live Demos\App_Data\Database.mdb*

3. Drag the "Database.mdb" file to the project in the Solution Explorer.
