.net - 调用中继器内的按钮或下拉列表

Question

我有一个 label和 dropdownlist里面repeater .当我单击中继器外的按钮时，我想访问 label.Text值和 ddl.SelectedIndex值(value)。

<asp:Repeater ID="rptProduct" runat="server" DataSourceID="objdsProduct" OnItemCommand="rptProduct">
   <ItemTemplate>
   <div>
      <div>
         <asp:Label ID="lblProdName" runat="server" Text='<%# Eval("ProductName") %>'></asp:Label>
      </div>
      <div>
         <asp:DropDownList ID="ddlSize" runat="server" AutoPostBack="False" DataSourceID="objdsSize"  DataTextField="SizeName" AppendDataBoundItems="True" DataValueField="SizeID">
            <asp:ListItem Text="select a size" Value=0></asp:ListItem>
         </asp:DropDownList>
   </div>
   </ItemTemplate>
</asp:Repeater>

<asp:Button ID="btnChoose" runat="server" Text="Choose Products" />

我如何访问 lblProdName.Text 的任何建议和 ddlSize.SelectedValue之内:

Protected Sub btnChoose_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnChoose.Click

   Dim ProductName
   Dim Size

End Sub

感谢您的时间。

将此添加到您的按钮单击:

Dim item As RepeaterItem
For Each item In  rptProduct.Items
    Dim ProductName As String = DirectCast(item.FindControl("lblProdName"), Label).Text   
Dim Size As Integer = (DirectCast(item.FindControl("ddlSize"), DropDownList).SelectedValue
Next item
