basic custom widget designer question

  • basic custom widget designer question
  • Very new to Sitefinity so I am sure this will be a easy one (not for me).

    I used Thunder to create the default "Hello World" custom widget and designer ... just so I could play with it.   I called it "HelloWorldTest"

    The strange thing is, when I look at the code that is generated I see a basic  HelloWorldTest.ascx but without any code behind.    

    <%@ Control Language="C#" %>
    <asp:Label ID="MessageLabel" Text="Text" runat="server"/>

    There is also the designer and a HellowWorldTest.cs file, but I see no way in which these files are linked. 

    As expected, when I registered this widget in tools and placed it on a page it just displays "Text", and when it click "Edit" it gives me the standard designer without the "Message" property.

    Am I supposed to add some code behind to the ASCX file to bootstrap the registering of the custom property and designer?

    I have a feeling I am missing the obvious here, but have been struggling for a while.

    Any hints would be greatly appreciated.
  • Hello Sheldon,

    You have created a user control. More information about user control, you can find in Sitefinity documentation:

    If you look in your HelloWorldTest.cs file, you will find a field referencing the layout template path:
    public static readonly string layoutTemplatePath = "~/HelloWorldTest.ascx";

    which is used in LayoutTemplatePath property:
    public override string LayoutTemplatePath
            if (string.IsNullOrEmpty(base.LayoutTemplatePath))
                return HelloWorldTest.layoutTemplatePath;
            return base.LayoutTemplatePath;
            base.LayoutTemplatePath = value;

    You can also consider watch this nice video tutorial made by Gabe Sumners for User Controls and Control Designers in Sitefinity:

    I hope this helps.
