Provides the ability to associate a dynamic builder with a custom property of a Web Part.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Implement the method in your WebPart when you want to associate a dynamic builder with a custom property. The method is called only when a property has its HtmlDesignerAttribute set to a BrowserBuilderType value of Dynamic. The method you implement in your WebPart should accept the property name as a string and generate a URL that will launch the dynamic builder for that property. The URL itself should point to an ASPX or HTML file that can be launched inside a ShowModalDialog method to complete the builder functionality.
If the assembly for your builder is deployed as a class resource, you must deploy the assembly in the global assembly cache. Assemblies deployed in the \inetpub\wwwroot\bin folder will not be allowed to use ASPX or ASMX files as class resources.
