当我进行更新时，我到底如何找到 DataKey？我什么都试过了...

Private Sub rtlAccounts_UpdateCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.TreeListCommandEventArgs) Handles rtlAccounts.UpdateCommand
    Dim txtAccountDescription As RadTextBox = TryCast(e.Item.FindControl("txtAccountDescription"), RadTextBox)
    Dim txtAdminName As RadTextBox = TryCast(e.Item.FindControl("txtAdminName"), RadTextBox)
    Dim txtAdminEmail As RadTextBox = TryCast(e.Item.FindControl("txtAdminEmail"), RadTextBox)
    Dim rcbStatus As RadComboBox = TryCast(e.Item.FindControl("rcbStatus"), RadComboBox)
    Dim rntDocRetention As RadNumericTextBox = TryCast(e.Item.FindControl("rntDocRetention"), RadNumericTextBox)

    Dim item As TreeListEditableItem = TryCast(e.Item, TreeListEditableItem)
    Dim MyDataKeyID As String =  'Now what???
End Sub

还想知道如何从 InsertCommand 和 UpdateCommand 中找到 ParentDataKeyValue。

要获取 DataKeyValue 和 ParentDataKeyValue，请将最后两行更改为以下内容：

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()

根据Telerik 的文档，如果您使用InPlace编辑模式，您应该将其TreeListEditableItem转换为TreeListDataItem; 如果您使用的是EditForms，则应将其TreeListEditableItem转换为TreeListEditFormItem.

为了让 GetDataKeyValue 和 GetParentDataKeyValue 返回您想要的值，您必须在定义 RadTreeList 时在各自的 DataKeyNames 和 ParentDataKeyNames 值中设置它们：

<telerik:RadTreeList ID="EmployeeTreeList" runat="server" 
    DataKeyNames="EmployeeID" 
    ParentDataKeyNames="ReportsTo">
    <Columns>
        <%-- Add column definitions here --%>
    </Columns>
</telerik:RadTreeList>
