821版，SQL动态加载出现如下问题：

出库主表代码说明：
窗口AfterLoad代码如下：

Dim cmd As New SQLCommand 
Dim dt As DataTable 
cmd.C 
cmd.CommandText = "SELECT DISTINCT 省市,客户名称 From 出库主表" 
dt = cmd.ExecuteReader() 
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1") 
trv.BuildDataTree(dt, "","省市","客户名称")

目录树的NodeMouseDoubleClick代码如下：
Dim Value()As String 
Dim Filter As string 
Value = e.Node.FullPath.Split("\") 
Select Case e.Node.Level 
    Case 0 
        Filter ="[省市] = '" & Value(0) & "'" 
    Case 1 
        Filter ="[省市] = '" & Value(0) & "' And [客户名称] = '" & Value(1) & "'" 
End Select 
DataTables("出库主表").LoadFilter = Filter 
DataTables("出库主表").Load()
 
Dim dst As WinForm.DataList = e.Form.Controls("DataList1") 
dst.DataTable = DataTables("出库主表") 
dst.Build()

项目BeforeLoadOuterTable动态加载的代码：

If e.DataTableName = "出库主表" AndAlso e.User.Name = "开发者" Then
e.SelectString = "Select * From 出库主表 Where ID < 0"
End If

If e.DataTableName = "出库明细" AndAlso e.User.Name = "开发者" Then
e.SelectString = "Select * From 出库明细 Where ID < 0"
End If

窗口中的目录树不能加载

不行，还是提示错误
