Question

我有两个嵌套的中继器，我想在repeater1中调用repeater2数据绑定器。为什么？好吧，我需要重复一些repeater2行。但我尝试这个，repeater2只工作一次，应该工作4次。请帮助！

受保护的Sub Repeater1_ItemDataBound（ByVal sender As Object，ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs）处理Repeater1.ItemDataBound

    For i = 0 To 4
        con.Open()
        Dim consulta As String = "SELECT DISTINCT Ordenes.Orden, Ordenes.Id, Ordenes.Codigo, Ordenes.Descripcion, Ordenes.Cantidad, Ordenes.PrecioVenta, " & _
        "Ordenes.FechaCreacion, Inventario.CostoUnitario, Inventario.Marca, Inventario.Garantia, Inventario.Modelo, Inventario.Color, Inventario.Serial, " & _
        "Inventario.CodigoFabricante, Clientes.Nombres, Clientes.Apellidos, Inv_Imagenes.Enlace FROM Ordenes INNER JOIN Inventario ON Ordenes.Codigo = " & _
        "Inventario.Codigo INNER JOIN Clientes ON Ordenes.IdCliente = Clientes.IdCliente INNER JOIN Inv_Imagenes ON Ordenes.Codigo = Inv_Imagenes.Item WHERE " & _
        "(Ordenes.id = @idt) AND (Inv_Imagenes.Tipo = 'img') AND (Inv_Imagenes.Orden = 1)"

        cmd = New SqlCommand(consulta, con)
        cmd.Parameters.AddWithValue("@idt", e.Item.DataItem("id").ToString)
        dr = cmd.ExecuteReader
        Dim Repeater2 As Repeater = e.Item.FindControl("Repeater2")
        Repeater2.DataSource = dr
        Repeater2.DataBind()
        dr.Close()
        con.Close()
    Next

End Sub

您可以使用e.Item.ItemIndex

进行测试

If (e.Item.ItemType = ListItemType.Item) Or _
            (e.Item.ItemType = ListItemType.AlternatingItem) Then

            //Treat with e.Item.ItemIndex


 End If
