ASP.NET用户控件设计器支持

Question

I have a user control which when added to the markup via the Toolbox or manually typing <myNameSpc:myCtrl ... I would like to spit out:

<myNameSpc:myCtrl>

     <template></template>

</myNameSpc:myCtrl>

I remember doing this for windows workflows and it involved implementing something like a TypeConverter and WorkflowXmlSerializer so it maybe possible for user controls as well I'd guess ? the only thing is that I don't have time to research this matter now, so I was wondering if anyone would be kind enough to point me in the right direction so that I don't have to dig deep into the designer serialization of VS (which I remember was a big pain).

Answer 1

For your custom control, you can specify a ToolboxDataAttribute which defines the default html that will be generated when you drag a control onto the design service. Eg:

[ToolboxData("<{0}:myCtrl runat="server"><template></template></{0}:myCtrl>")]
public class myCtrl : System.Web.UI.Control
{

}

Answer 2

For the manual generation you can create a Code Snippet . The best way to do that is find existing ASPX snippet and modify it to gen your control. I'm assuming you are using VS 2010.
