一个简单的自定义控件，如何在一个之间加入一行字？

[webfactory]

新手，麻烦给写段小代码？庥烦写详细点

我想做一个自定义控件，在一个<div></div>之间加入一行文字，比如<div>你好，中国</div>

在控件开头加入
public class myDiv:System.Web.UI.WebControls.Panel ,System.Web.UI.INamingContainer

请问在什么地方处理继承来的Panel，将其中间加入文字

[webfactory]

我想用继承的这个System.Web.UI.WebControls.Panel(它实际上就是生成一个<div>)，用这个（HtmlTextWriter output）来重写一下它生成的内容

[timeislife]

protected override void Render(HtmlTextWriter output)
{
output.Write("<div>北京</div>");
}

public class MyPanel: System.Web.UI.WebControls.Panel
{
[Browsable[true])
public string Text
{
get { return _text; }
set { _text = value; }
}
private string _text = "";
....
protected override void Render(HtmlTextWriter output)
{
output.Write("<div>"+_text+"</div>");
}
....
}

protected override void Render(HtmlTextWriter output)
{
output.Write("<div>北京</div>");
}

这个函数就是用来输出控件外观的

there is the disassembler of Panel:

public class Panel : WebControl
{
// Methods
public Panel();
protected override void AddAttributesToRender(HtmlTextWriter writer);

// Properties
[WebCategory("Appearance"), Editor("System.Web.UI.Design.ImageUrlEditor, System.Design, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor)), WebSysDescription("Panel_BackImageUrl"), Bindable(true), DefaultValue("")]
public virtual string BackImageUrl { get; set; }
[WebSysDescription("Panel_HorizontalAlign"), DefaultValue(0), WebCategory("Layout"), Bindable(true)]
public virtual HorizontalAlign HorizontalAlign { get; set; }
[WebCategory("Layout"), DefaultValue(true), WebSysDescription("Panel_Wrap"), Bindable(true)]
public virtual bool Wrap { get; set; }
}

<div id="div1"></div>

div1.innerHTML = "北京";

不能把这个output当作字符串，Replace">"一下吗？

[minghui000]

protected override void Render(HtmlTextWriter output)
{
output.Write("<div>"+_text+"</div>");
}

路过一下捡分。

[ControlBuilder(typeof(InnerTextLabelControlBuilder)),
ParseChildren(false),
DefaultProperty("Text"),
ToolboxData("<{0}:InnerTextLabel runat=server></{0}:InnerTextLabel>")]
public class InnerTextLabel : System.Web.UI.WebControls.WebControl
{
protected override HtmlTextWriterTag TagKey
{
get
{
return HtmlTextWriterTag.Label;
}
}
[Bindable(true),
Category("Appearance")]
public string Text
{
get
{
string s = (string)ViewState["Text"];
return (s == null)? string.Empty:s;
}
set
{
ViewState["Text"] = value;
}
}
protected override void AddParsedSubObject(object obj)
{
if(obj is LiteralControl)
{
Text = ((LiteralControl)obj).Text;
}
else
{
throw new ArgumentException("。。。。");
}
}
/// <summary>
/// 将此控件呈现给指定的输出参数。
/// </summary>
/// <param name="output"> 要写出到的 HTML 编写器 </param>s
protected override void Render(HtmlTextWriter writer)
{
writer.Write(HttpUtility.HtmlEncode(Text));
}
}
