Question

我想自定义一个可以像这样使用的webcontrol：

<cc1:TitleEx runat="server" Theme="Sky" DemoUrl="what.swf" Left="150" Width="250">
       <asp:Literal ID="Literal1" runat="server"></asp:Literal>
</cc1:TitleEx>

基类是：

[Bindable(true)]
[Category("Appearance")]
[DefaultValue("")]
[Localizable(true)]
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public string Text
{
   get
   {
    String s = (String)ViewState["Text"];
    return ((s == null) ? String.Empty : s);
   }
   set
   {
    if (this.HasControls())
     {
        this.Controls.Clear();
     }
    ViewState["Text"] = value;
   }
  }

/// <summary>
/// child control's content
/// </summary>
protected StringBuilder HtmlContent = new StringBuilder();

protected override void AddParsedSubObject(object obj)
{
  if (obj is LiteralControl)
  {
    HtmlContent.Append(((LiteralControl)obj).Text);
    this.Text = HtmlContent.ToString();
  }
  else
  {
   if (obj != null)
   {
     HtmlContent.Append(GetControlHtml(obj as Control));
     this.Text = HtmlContent.ToString();
   }
  }
}

/// <summary>
/// get the child controls' html
/// </summary>
protected string GetControlHtml(Control ctl)
{
   StringBuilder sb = new StringBuilder();
   StringWriter tw = new StringWriter();
   HtmlTextWriter writer = new HtmlTextWriter(tw);
   ctl.RenderControl(writer);
   sb.Append(writer.InnerWriter.ToString());
   return sb.ToString();
}

我的问题是当我在Page_Load()中将字符串设置为此文字控件时，但字符串无法显示。我也尝试在OnPreInit()，OnPreLoad()中设置值，但仍然没有运气。

以前有人遇到过这个问题吗？

你如何解决这个问题？

我通过反映小组找到了答案。这是我的解决方案.http：//www.cnblogs.com/coolkiss/archive/2010/12/30/1921494.html

Web Control包含另一个Web Control？
