Where is the SItecore command "ide:startwizard" located?

Sitecore has the concept of commands which are defined in co开发者_JAVA百科mmands.config and point to a class with Execute() method.

In the core database under the following item:

/sitecore/content/Applications/Layouts/IDE/New File/Renderings/Sublayout

the command ide:startwizard is invoked. Where is the commands.config entry for this command and where is the class that is used for this command?

There is no customizable class for this. This command is not in the Commands.config file. Based on what I see in the core database at the item you specified, this is such a built-in integral part of the internal Sitecore framework, this class is likely in one of the Sitecore DLLs, Kernel or Client.

This looks like it is using Sitecore.Web.UI.HandleMessage attribute. Take a look in Sitecore.Shell.Applications.Layouts.IDE.IDEForm if you want to see what the method is doing.
