The following steps will show how to do this in your template controls, assuming you already have a template control ( template controls are web server controls that have one or many properties of type ITemplate ).

So, this is how it works :

  1. Implement a custom designer that inherits from System.Web.UI.Design.ControlDesigner
  2. Override the TemplateGroups Collection.
  3. In the get define your template group collection and return it.
  4. Don't forget to enable TemplateEditing flag.

The Sample I introduce here contains a template control having 4 templates which I divide them into 2 template groups.

The Control Desginer

The final output of the sample looks like this

Here's the code so have fun.

  1. This example is awesome, thanks for sharing, but why i cannot write in the template? I tried the tempDef1.AllowEditing but its read only :(

    btw, im very excited to learn how to do professional webcontrols, can you recommend me a good book or page or something :$
