    Hello Marcus Lambert,

    Straight to your questions:
    The SelectedValuePath specifies the path (normally the name of the property) that will be used to resolve the SelectedValue depending on the SelectedItem.

    Example: You have an Entity Person which has a property FirstName.

    If you set the SelectedValuePath to "FirstName" then the SelectedValue property will equal the value of the FirstName for the selected entity, e.g. "John"

    I understand that the name of the property may be mistaken for "The Path of the SelectedItem". The easiest way to retrieve this is to call


    For your second question:
    The path for an item is built by calling .ToString(). By default the method returns the class name so this is why you see this strange path.

    You can override the ToString method for your items or set the TextSearch.TextPath property on the TreeView that will specify the property that will be sued to build that path, i.e.:

    telerik:TextSearch.TextPath = "Id"

    If you have and Id property on your items, it will be used to create the path.

    Then you can use  this same path for methods like GetItemByPath or ExpandItemByPath.
