Sitecore: How to use sublayout parameters from codebehind?

Question

How do I get the values from the \"Parameters\" field (second screenshot) in the code-behind of the sublayout?

I understand I can get/set parameters

Answer 1

Like this:

var sublayout = ((Sublayout)this.Parent);
NameValueCollection nvc = Sitecore.Web.WebUtil.ParseUrlParameters(sublayout.Parameters);

Here's a blog post that make it easier to do with extension methods.

Here's a shared source module for Sitecore that wraps this up in a class as well. It was written by John West, CTO of Sitecore USA.

Answer 2

You can get the parameters defined on the sublayout but it's a bit long winded. You need to find the correct rendering item first and from there retrieve the parameters

   var sublayout = ((Sublayout)this.Parent);
   //Get all rendering
   var renderings = Sitecore.Context.Item.Visualization.GetRenderings(Sitecore.Context.Device, true);

   //Get the first rendering that matches the current sublayout's path
   var sublayoutRendering = renderings.FirstOrDefault(r => r.RenderingItem.InnerItem["Path"] == sublayout.Path);

   if (sublayoutRendering != null)
         Response.Write(sublayoutRendering.RenderingItem.Parameters);

You can use Mark's way to get the parameters for the parameters set in the "Layout Details"

EDIT: The above solution will work but it's very fragile and depends on sitecore internals that might change in the future. I wouldn't recommend you go with it in production with it. There must be a better way to achieve what you want.
