Question

我有一个动态创建的表。该表只有一个字段 - 类别。从每个类别我创建一个按钮。我希望每个按钮都重定向到特定页面。每个页面的aspx都有一个类别名称.aspx。 有没有办法动态地执行此操作？我使用Selected Case创建了这个，但这不适合我，因为我每次都会创建和删除类别

Using myCommand As New SqlCommand("SELECT kategorie FROM Kategorie", myConn)
            Using myDataReader As SqlDataReader = myCommand.ExecuteReader

                While myDataReader.Read()

                    Dim tRow As New TableRow()
                    tblKategorie.Rows.Add(tRow)

                    Dim tCell As New TableCell()
                    tRow.Cells.Add(tCell)

                    Dim buttKategorie As New Button
                    buttKategorie.Text = myDataReader("kategorie")
                    buttKategorie.CssClass = "buttKategorie"

                    **'Here I tried to do it > ????**
                    'buttKategorie.PostBackUrl = myDataReader("kategorie.aspx")

                    tCell.Controls.Add(buttKategorie)

                End While
            End Using
End Using

<强> XAML：

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:panel runat="server" id="container"></asp:panel>    
</asp:Content>

我使用了一个列表，但你可以改变它。

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim source As New List(Of String)
    source.Add("page1.aspx")
    source.Add("page2.aspx")
    For Each tmp As String In source
        Dim btn As New Button
        btn.Text = tmp
        btn.ID = tmp
        AddHandler btn.Click, AddressOf Me.Button_Click
        container.Controls.Add(btn)
    Next
End Sub

Private Sub Button_Click(sender As Object, e As EventArgs)
    Dim btn As Button = CType(sender, Button)
    Response.Redirect(btn.Text)
End Sub

使用PostBackUrl ASP.NET
