C# C Winforms将RadTreeView元素绑定到数据源，ValueMember异常

我在将RadTreeView元素绑定到数据源时遇到了一个问题，实际上是在设置ValueMember时。简言之，有：

型号：

/// Parent
public class EmfLocation 
{
    public int ID { get; set; }
    public string Name { get; set; }
    public virtual ICollection<EmfDataSet> EmfDataSets { get; set; }
}

/// Child
public class EmfDataSet
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int EmfLocationID { get; set; }
}

怎么了

/// treeDataset = new Telerik.WinControls.UI.RadTreeView();

private void GetTreeData()
{
    IList<EmfLocation> locationList = new List<EmfLocation>();
    locationList = repoEmfLocation.GetBy(testingId).ToList();

    treeDataset.DataSource = locationList;
    treeDataset.DisplayMember = "Name\\Name";
    treeDataset.ChildMember = "locationList\\EmfDataSets";
    treeDataset.ValueMember = "ID\\ID";
}

"Property accessor 'ID' on object 'System.Data.Entity.DynamicProxies.EmfDataSet_5F54359CCE6567583EDAE4FA2B61B7D274184C3985DAC9FE14B234AFFEE42F1B' threw the following exception:'Object does not match target type.'"
