Sharepoint web parts Rendering html and controls

sharepointsharepoint-2007web-parts

I have a webpart that displays HTML output within the RenderWebPart method and also creates controls within the CreateChildControls both methods are declared as overridden in the webpart.

My question is how to I control the order of the display of the controls and html output?

At the moment I call EnsureChildControls() within the RenderWebPart mthod to ensure all controls within the CreateChildControls are created and then the html out is rendered.

What if I wanted to display a control on the page then html output and then another control below in that order?

I would recommend moving all of your static HTML out of the Render function and into the CreateChildControls function. If you need to, you can add regular old HTML using Labels, WebControls, or even better... LiteralControls. Then you can just add them to your Controls collection.

Example:

WebControl container = new WebControl(System.Web.UI.HtmlTextWriterTag.Div);
StringBuilder sb = new StringBuilder();
sb.Append("<ul>");
foreach (Node child in this.Children)
{
    sb.AppendFormat("<li><a href=\"{0}\">{1}</a></li>", url, name);
}
sb.Append("</ul>");
LiteralControl l = new LiteralControl();
l.Text = sb.ToString();
container.Controls.Add(l);
