我有一个用户控件,上面有一个面板:
CustomControl.ascx
<%@ Control Language="vb" CodeBehind="CustomControl.ascx.vb" %>
<asp:Panel ID="myPanel" runat="server"></asp:Panel>
我希望将该面板公开为我可以在设计时使用的属性。
CustomControl.ascx.vb
<ParseChildren(True), PersistChildren(False)> _
Partial Public Class CustomControl
Inherits System.Web.UI.UserControl
#Region "Members and Properties"
<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property SomePanel() As Panel
Get
Return myPanel
End Get
Set(ByVal value As Panel)
myPanel= value
End Set
End Property
#End Region
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(myPanel.HasControls.ToString())
End Sub
End Class
然后将控件带到这样的页面上:
<ucl:CustomControl runat="server">
<SomePanel>
<asp:Label ID="lblText" AssociatedControlID="txtBox" runat="server"></asp:Label>
<asp:TextBox id="txtBox" runat="server"></asp:TextBox>
</SomePanel>
</ucl:CustomControl>
当我运行页面时,HasControls为true但没有呈现任何内容。我做错了什么?

通过将用户控件设计为模板控件,可以获得类似的效果。如果你选择去模板路线,那么设置并不难。
