Dynamically generated ASP.NET page hasn't basic html structure

Question

i wrote a page (only class that derives from System.Web.UI.Page , that i want to use in more websites. I dynamically add webcontrols to Page.Controls collection like this:

Panel p = new Panel();
p.Style.Add("float", "left");
p.Controls.Add(locLT);
Page.Controls.Add(p);

this code renders only

<div style="float:left;">
</div>

How can i add HTML, HEADER and BODY section without manually write this? Is it possible?

Answer 1

I recommend MasterPages but you can do this:

public class CustomBase : System.Web.UI.Page  
{    
    protected override void Render( System.Web.UI.HtmlTextWriter textWriter ) 
    {
        using (System.IO.StringWriter stringWriter = new System.IO.StringWriter())
        {
             using (HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter))
             {    
                 LiteralControl header =new LiteralControl();
                 header.Text = RenderHeader(); // implement HTML HEAD BODY...etc

                 LiteralControl footer = new LiteralControl();
                 footer.Text = RenderFooter(); // implement CLOSE BODY HTML...etc

                 this.Controls.AddAt(0, header); //top
                 this.Controls.Add(footer); //bottom

                 base.Render(htmlWriter); 
             }
        }

        textWriter.Write(stringWriter.ToString());
    }       

}

我不相信有任何方法可以自动生成标记，但是您可以创建自己的Render方法，以输出所需的基本HTML框架。

Before using MasterPages a common way to add header and footer for a page was to inherit from a BasePage like http://gist.github.com/214437 and from the BasePage load header and footer controls. I think that a MasterPage is better choice for you than the BasePage above. One of the drawbacks with a MasterPage is that you have to add asp:content at every page but it's still better than the old way.

如果您的“页面”是完全动态的并且没有aspx前端（我没有意识到这是可能的吗？！）……那么您真正想要的可能是自定义HttpHandler而不是从Page继承。
