This demo shows how to bind the ASPxTreeList control to an MS Access database.
Since the ASPxTreeList is designed to display information in a tree structure, its data source should meet certain requirements.
Two additional fields are necessary to build a tree structure.
The first field must contain unique values. This field must be assigned to the KeyFieldName property.
The second field must contain values that indicate parent nodes for the current node. It should be assigned to the
ParentFieldName property. Columns bound to these fields are called Service columns.
In this demo, toggle the 'Show service columns' check box to display or hide service columns.
