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?
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());
}
}
I don't believe there is any way to automatically generate the tags, but you can create your own Render method that outputs the required basic HTML framework.
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.
If your "page" is completely dynamic and has no aspx front-end (I didn't realize this was possible?!)... then what you really want is probably a custom HttpHandler rather than inheriting from Page.
