Partial View with parametrized prefix for controls names

Question

I have a BarEditor.ascx, that can be called from diffent places.

<%@ Control Language=\"C#\" Inherits=\"System.Web.Mvc.ViewUserControl

        

Answer 1

just create a ViewModel class for your BarEditor and make it strongly typed to this new class

e.g.

namespace ViewModel {
    public class BarEditor {

        string Prefix { get; set; }
        Models.Bar Bar { get; set; }
    }
}

now you create your textbox in BarEditor.ascx like this

<%= Html.TextBox(Model.Prefix + ".a") %> 

and in your view you include the BarEditor like that

 

    

        <% Html.RenderPartial("BarEditor", new ViewModel.BarEditor { Prefix = "Bar", Bar = ViewData["bar"]}); %>
    
    

        <% Html.RenderPartial("BarEditor", new ViewModel.BarEditor { Prefix = "Baz", Bar = ViewData["baz"]}); %>
