Response.Redirect --如何

Question

我试图弄清楚如何使用Response.Redirect VB中的“ASP.NET”从一个网格视图中获取两列，如果可能的话，从同一页的下拉列表中获取两列，并将其发送到下一页的标签。这个是可能的吗？

另外，我还有点不明白它写着“房间和名字”的地方。我在哪里找到这些正确的输入？谢谢你的帮助。

更新：

    Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged

    Response.Redirect("RoundingEntry.aspx?Room=" & GridView1.SelectedRow.Cells(1).Text & "&Name=" & GridView1.SelectedRow.Cells(2).Text & "&Rounder=" & DDRounder.SelectedValue)

    End Sub

在我的下一页/接收页上我有这个..。

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    If Me.Page.PreviousPage IsNot Nothing Then
        Dim rowIndex As Integer = Integer.Parse(Request.QueryString("RowIndex"))
        Dim GridView1 As GridView = DirectCast(Me.Page.PreviousPage.FindControl("GridView1"), GridView)
        Dim row As GridViewRow = GridView1.Rows(rowIndex)

        Dim room As String = Request.QueryString("Room")
        Dim name As String = Request.QueryString("Name")
        Dim Rounder As String = Request.QueryString("Rounder")
        lblRoom.Text = room
        lblPatientName.Text = name
        lblRounder.Text = Rounder

    End If
End Sub

lblRoom.Text源代码

<asp:Label ID="lblRoom" runat="server" BackColor="White" Height="22px" 
     Width="100px" BorderColor="#CCCCCC" BorderStyle="Inset" BorderWidth="1pt" 
     style="text-align: center; background-color: #CCCCCC;"></asp:Label>

如果需要上一页上的控件的值，则可以使用Server.Transfer("page.aspx")。

如果您通过querystring，请使用Request.QueryString("Room") & Request.QueryString("Name")

看看这个article

你在这里想念RowIndex ..。

Response.Redirect("RoundingEntry.aspx?Room=" & GridView1.SelectedRow.Cells(2).Text & "&Name=" & GridView1.SelectedRow.Cells(3).Text "&RowIndex=?")

在下一页..。

Dim rowIndex As Integer = Integer.Parse(Request.QueryString("RowIndex"))
Dim room As String = Request.QueryString("Room")
Dim name As String = Request.QueryString("Name")
lblRoom.Text = room 
lblName.Text = name
