PORender Self-Closing Tag in ASP.NET custom control derived from Control
text
Body
copied!<p>I'm working on a Facebook FBML controls library and would like to create my FBML controls somewhat patterned like the ASP.NET WebControls library. I have a base class that handles rendering by default; here's my render method:</p> <pre><code> protected override void Render(HtmlTextWriter writer) { AddAttributesToRender(writer); if (UseXfbmlSemantics) { writer.RenderBeginTag(ElementName); writer.EndRender(); writer.RenderEndTag(); } else { writer.RenderBeginTag(ElementName); writer.RenderEndTag(); } } </code></pre> <p>What I would like is for the rendering to be modified based on UseXfbmlSemantics - if it's true, it should render, for instance:</p> <pre><code><fb:name uid="10300399458"></fb:name></code></pre> <p>When it's false, it should render with a self-closing tag:</p> <pre><code><fb:name uid="10300399458" /></code></pre> <p>I can get the "true" condition to work almost correctly, but the self-closing tag seems to be incompatible with the Render- set of methods. Unfortunately if that's the case it also means that the AddAttributesToRender pattern wouldn't work, either. What it's actually producing is this:</p> <pre><code> <fb:name uid="10300399458"> </fb:name> </code></pre> <p>How can I get HtmlTextWriter (or which HtmlTextWriter do I need to use) to make it render a self-closing tag? Or, at the very least, how can I make it not render that interim space (so that the opening and closing tags are immediately next to one another)?</p>

Querying!
