asp.net mvc避免if-视图中控件的其他逻辑

Question

i have next code in my View:

   @if (Model is Manager)
        {
           //render manager button
        }
        else if (Model is Developer)
        {
            //render Developer button
        }
        else if (Model is UX)
        {
            //render UX button
        }

This works, but I'm looking best way to do it. Any idea?

You can use extension method to implement control logic for different entities.

 public static MvcHtmlString userButton(this HtmlHelper html, Manager user)
    {
        string buttonForManager = //...
        return new MvcHtmlString(buttonForManager);
    }

    public static MvcHtmlString userButton(this HtmlHelper html, Developer user)
    {
         string buttonForDeveloper = //...
        return new MvcHtmlString(buttonForDeveloper);
    }

Use in View:

@Html.userButton(Model)
