我试图弄清楚如何使用 ASP.NET VB 中的“Response.Redirect”从 gridview 中获取两列，如果可能的话，从同一页面上的下拉列表中获取并将其发送到下一页上的标签。这可能吗？

另外，我对理解“房间和名称”的位置感到有点困惑。我在哪里可以找到这些的正确输入？感谢您的任何帮助。

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

在我的下一个/接收页面上，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 的源代码

<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>

Server.Transfer("page.aspx")如果您想要来自上一页控件的值，您可以使用。

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

article也看看这个

您在这里缺少 RowIndex ...

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

然后在下一页...

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
