关于解决方案: ASP.Net: User control with content area, it's clearly possible but I need some details
我正在尝试做同样的事情,这是我的代码:
背后的控制代码:
[ParseChildren(true, "Content")]
[PersistChildren(false)]
public partial class SlidingPanelControl : System.Web.UI.UserControl
{
protected override void OnInit(EventArgs e)
{
phContent.Controls.Add((Control)_content);
base.OnInit(e);
}
protected void Page_Load(object sender, EventArgs e)
{
}
private PlaceHolder _content;
[PersistenceMode(PersistenceMode.InnerProperty)]
public PlaceHolder Content { get { return _content; } set { _content = value; } }
}
控制ASPX:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SlidingPanelControl.ascx.cs" Inherits="Photography.Controls.MbExtruder.SlidingPanelControl" %>
<div>
<asp:Panel ID="pnlLockable" runat="server" Visible="False">
<asp:PlaceHolder runat="server" ID="phContent" />
</asp:Panel>
</div>
这就是我在主页中使用控件的方式:
<uc1:SlidingPanelControl runat="server" ID="SlidingPanelControl"
Title="About" Position="right" Opacity="1" WidthInPixels="600">
<Content><h1>hello world</h1></Content>
</uc1:SlidingPanelControl>
这对我不起作用,它没有将html渲染到控件占位符中。虽然当我调试控件的OnInit时,我可以看到_content控件具有我设置的所有html(在此示例中为<h1>Hello World</h1>
)
任何猜测我做错了什么?
由于
答案 0 :(得分:0)
好的,所以我在我的电脑上查了一下,我找到了真正有用的解决方案:
[ParseChildren(false)]
[PersistChildren(false)]
public partial class WebUserControl1 : System.Web.UI.UserControl
{
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
if (Content != null)
{
ContentContainer container = new ContentContainer();
Content.InstantiateIn(container);
phContent.Controls.Add(container);
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
private ITemplate _content;
[PersistenceMode(PersistenceMode.InnerDefaultProperty),
DesignerSerializationVisibility(DesignerSerializationVisibility.Content),
TemplateInstance(TemplateInstance.Single)]
public ITemplate Content
{
get
{
return _content;
}
set
{
_content = value;
}
}
}
public class ContentContainer : Control, INamingContainer
{
}
我自己检查了它的魅力。其他来源的代码与您的相同。
