c# - 访问控件: Nested repeater

Question

我如何获得位于另一个转发器中的文本框？

<asp:Repeater ID="Repeater1" runat="server">
 <ItemTemplate>
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
      <asp:Repeater ID="Repeater2" runat="server">
         ....
       </asp:Repeater>
  </ItemTemplate>
</asp:Repeater>

我在repeater2 ItemDataBound 中，我需要获取TextBox1 的值，我该怎么做。

 Protected Sub Repeater2_ItemDataBound(sender As Object, e As System.Web.UI.WebControls.RepeaterItemEventArgs)  

??

    End Sub

Answer 1

内层repeater的NamingContainer是外层Repeater的RepeaterItem，然后使用FindControl获取对 TextBox 的引用:

protected void Repeater2_ItemDataBound(Object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        Repeater innerRepeater = (Repeater) sender;
        RepeaterItem outerItem = (RepeaterItem) innerRepeater.NamingContainer;
        TextBox TextBox1 = (TextBox) outerItem.FindControl("TextBox1");
    }
}
