我面临着从文本框中读取值的困难情况，该文本框动态添加到 AjaxTabContainer 的 TabPanel 内的 gridview 中。

请注意，所有控件都是根据用户选项动态添加的。

顺序如下：

  
Design Time:
One Panel and other user options (date & some other fields)

Run Time:
- Add AjaxTab container & Tab Panel which is vary upon user filter (Tab created based on db -records)
- Inside each tab, added the GridView with dataset
- Add some textbox into each of GridView Line

在页面上：我可以使用带有文本框的 gridview 成功显示选项卡控件（*如下）动态文本框 现在，当用户单击“更新”按钮时，如何读取每个文本框中的值？我尝试使用 FindControls，但没有。

我的代码：-


Private Sub DynamicTabGVLoad(ByVal seqno As String)
        createTab()
        ds = allotmentdb.getRoomType()
        For i As Integer = 0 To ds.Tables(0).Rows.Count - 1
            Dim tabcontent As New Control()
            Dim tbldynamic As New Table()
            Dim tbrdynamic As New TableRow()
            Dim tbcdynamic As New TableCell()

            roomtypekey = ds.Tables(0).Rows(i)("roomtypekey").ToString()
            Dim gv_alines As New GridView
            gv_alines.AutoGenerateColumns = True
            gv_alines.Attributes.Add("runat", "server")
            Dim ds1 As New Data.DataSet()
            ds1 = allotmentdb.getAllotmentLinesTabGV(roomtypekey, seqno, System.DateTime.Now.ToString(("yyyy-MM-dd")))
            gv_alines.EmptyDataText = "No Record Found!"
            'gv_alines.ShowHeaderWhenEmpty = True
            gv_alines.DataSource = ds1
            gv_alines.DataBind()
            If gv_alines.Rows.Count > 0 Then
                gv_alines.HeaderRow.Cells(0).Visible = False
                gv_alines.HeaderRow.Cells(1).Visible = False
                gv_alines.HeaderRow.Cells(4).Visible = False

            ajxTab.ActiveTabIndex = 0
        Next
    End Sub

我非常迫切需要它。提前致谢！
