关于DEV aspxgridview中 无法获取模板中控件的问题

[groundsky]

前端

<dx:GridViewDataTextColumn FieldName="附件" VisibleIndex="9">
                        <EditItemTemplate>
                            <dx:ASPxTextBox ID="txtAttach" runat="server" Text='<%# Bind("附件") %>' Width="170px">
                            </dx:ASPxTextBox>
                            <dx:ASPxUploadControl ID="uploadAttach" runat="server" OnFileUploadComplete="uploadAttach_FileUploadComplete" OnInit="uploadAttach_Init" ShowUploadButton="True" Theme="Aqua" UploadMode="Auto" Width="280px">
                                <AdvancedModeSettings EnableDragAndDrop="True">
                                </AdvancedModeSettings>
                            </dx:ASPxUploadControl>
                        </EditItemTemplate>
                    </dx:GridViewDataTextColumn>

后台：

 Dim txtattach As New ASPxTextBox
    Protected Sub uploadAttach_FileUploadComplete(sender As Object, e As FileUploadCompleteEventArgs)
        Dim newfile As String
        newfile = Help.AspxUploadHelper.GetNewFile(Server.MapPath("~/Uploadfiles/"), e.UploadedFile.FileName)
       
        e.UploadedFile.SaveAs(newfile)'上传文件

        e.CallbackData = newfile

        Me.hdNewfilename.Value = newfile ‘暂存保存文件名’


       Dim colAttach As New GridViewDataTextColumn

        colAttach = Me.ASPxGridView1.Columns("附件")

‘txtAttach 模板中aspxtextbox 的id’
        txtattach = Me.ASPxGridView1.FindEditRowCellTemplateControl(colAttach, "txtAttach")

        If txtattach Is Nothing Then
            txtattach = Me.ASPxGridView1.FindEditFormLayoutItemTemplateControl("txtAttach")
        End If
        If txtattach Is Nothing Then
            txtattach = Me.ASPxGridView1.FindEditFormTemplateControl("txtAttach")
        End If

表格中有“”附件“”字段，用于存放文件名称，试了3种发放始终不对，不知道为什么，求教？

另有些个别字段出现e.newvalues(“”名称“”)无法获取的情况，使用模板拖入 aspxtextbox 绑定，居然正常的。
