如何从一个页面（数据绑定）获取数据到asp.net中另一页面的文本框

Question

假设我有两个 .aspx 页面和一个连接 sql server 数据库引擎。

第一页，我们称它为 playground.aspx，我有一组数据绑定，它使用 SELECT 函数的存储过程（使用数据集）。

现在在第二个页面，我们称之为link.aspx，有两个文本框，假设playground.aspx页面中有多个数据，我想检索Entity Code和Username数据（从playground.aspx的数据绑定中）并将其显示在 link.aspx 的文本框中。

我该怎么做？ 我被告知要创建一些函数，但我之前从未处理过数据绑定，只有 TextBox 和 Label，这让我很困惑。

感谢您的帮助。

编辑（这是数据绑定代码）

 <asp:Panel ID="PanelDGV" runat="server" Height="100%" ScrollBars="None" Width="100%">
                                        <asp:GridView ID="DGV" runat="server" AutoGenerateColumns="False" GridLines="None"

我刚刚解决了问题，这是代码

对于链接.vb

Public Function F01_sysUser_Select(ByVal EntityCode As String, ByVal Username As String) As ProcessResult
    Try
        Dim SqlCmd As New SqlCommand()
        SqlCmd.Connection = New SqlConnection(CF.CfgConnectionString)
        SqlCmd.CommandType = CommandType.StoredProcedure
        SqlCmd.CommandTimeout = CF.CfgCommandTimeout
        SqlCmd.CommandText = "sysUser_SelectByID"
        SqlCmd.Parameters.Add("@EntityCode", SqlDbType.VarChar) : SqlCmd.Parameters(0).Value = EntityCode

        SqlCmd.Connection.Open()

        Dim Dr As SqlDataReader = SqlCmd.ExecuteReader(CommandBehavior.CloseConnection)
        F01_Dt_sysUser.Clear()
        F01_Dt_sysUser.Load(Dr)

        If F01_Dt_sysUser.Rows.Count > 0 Then
            Dr.Close()
            Dr = Nothing
            SqlCmd.Dispose()
            Return ProcessResult.SuccessWithResult
        Else
            Dr.Close()
            Dr = Nothing
            SqlCmd.Dispose()
            Return ProcessResult.SuccessWithNoResult
        End If

    Catch ex As Exception
        InsertErrorLog("PlaygroundLink.F01_sysUser_Select", ex.Message)
        ExMessage = ex.Message
        Return ProcessResult.Failed
    End Try

End Function

并在link.aspx.vb中：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim QSEntityCode As String
    Dim QSUserName As String
    QSEntityCode = Request.QueryString("QSEC").ToString
    QSUserName = Request.QueryString("QSUN").ToString

    Dim Bl As New PlaygroundLink
    If Bl.F01_sysUser_Select(QSEntityCode, QSUserName) = CF.ProcessResult.SuccessWithResult Then
        TbEntityCode.Text = QSEntityCode
        TbUsername.Text = QSUserName
    Else
        ' LblMessage.Text = Bl.ExMessage
    End If
End Sub

最后在 playground.aspx.vb:

Private Sub DGV_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles DGV.RowCommand
    If e.CommandName = "CmdEdit" Then
        Dim QSEntityCode As String
        Dim QSUserName As String
        Dim idx As Integer = Convert.ToInt32(e.CommandArgument)
        Dim row As GridViewRow = DGV.Rows(idx)
        QSEntityCode = row.Cells(0).Text
        QSUserName = row.Cells(1).Text
        Response.Redirect(RR.PlaygroundLink & "?QSEC=" & QSEntityCode & "&QSUN=" & QSUserName)
    End If
End Sub

之后，我得到了我想要的，在link.aspx 文本框中显示结果，干杯！ :)
