To fix the issue you can do To get the DataKeyValue and the ParentDataKeyValue, change your last two lines to the following:
code :
Dim editedItem As TreeListEditFormItem = CType(e.Item, TreeListEditFormItem)
Dim dataKeyValue As String = _
    editedItem.ParentItem.GetDataKeyValue("EmployeeID").ToString()
Dim parentDataKeyValue As String = _
    editedItem.ParentItem.GetParentDataKeyValue("ReportsTo").ToString()
<telerik:RadTreeList ID="EmployeeTreeList" runat="server" 
    DataKeyNames="EmployeeID" 
    ParentDataKeyNames="ReportsTo">
    <Columns>
        <%-- Add column definitions here --%>
    </Columns>
</telerik:RadTreeList>

wish helps you It is true that you cannot select the 'root' of the treelist, but you can place an item in the first column to add new items at root level as illustrated here: http://demos.telerik.com/aspnet-ajax/treelist/examples/dataediting/net35automaticdataediting/defaultcs.aspx.
To hide the edit button for root level items, listen to the ItemCreated event, locate the edit button in the root items only and set its Visible property to false. This should work for checkboxes or other server controls inside the treelist rows and you do not have to perform explicit loops through the items later on.

it fixes the issue The XItemsId is a clientside datakey only, you should change the getDataKey to use ChildId (you also have a typo in the dataKeyNames declaration
code :
private List<xItems> GetTreeListChanges()
{
    List<xItems> xItems = new List<xItems>();
    foreach(TreeListDataItem rtlItem in rtlxItems.Items)
    {
        string xItemsId = Convert.ToString(rtlItem.GetDataKeyValue("ChildId"));
    }
    [...]
} 

<telerik:RadTreeList ID="rtlxItems" runat="server" AllowMultiItemEdit="false"
        ParentDataKeyNames="ParentId" DataKeyNames="ChildId" ClientDataKeyNames="xItemsId">

help you fix your problem I have been working with Telerik RadGrids and I haven't had any problem setting all items to edit mode when I'm populating the grid. , The solution goes as follows:
code :
protected void RadTreeList1_PreRender(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        foreach (TreeListDataItem item in RadTreeList1.Items)
        {
            if (item is TreeListDataItem)
            {
                item.Edit = true;
            }
        }
        RadTreeList1.Rebind();
    }
}

To fix the issue you can do I am using a RadTreeList to display items, a RadContextMenu (Insert, Update, Delete) for when right clicking on a Tree Item and a RadWindowManager to help open a popup window on RadContextMenu ItemClick. When they click Insert or Update a dialog window opens smoothly they save, the dialog closes, treelist rebinds perfectly. When they click Delete I do not need to open a Window just run the code for deleting and then RadTreeList.Rebind(); , Please try with the below code snippet.
code :
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="rcMenu">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadWindowManager1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="RadTreeList" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="rcMenu" LoadingPanelID="RadAjaxLoadingPanel1" /> <%--Please remove this if not necessory--%>
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
