How Pass some parameter to MVC User Control that is not in ViewData

Question

I want to pass some parameters to my MVC UserControl like ShowTitle(bool) and the ViewData.Model.Row . How I define my usercontrol and pass them to it? Tanx

Answer 1

You can define your control as

public partial class MyUserControl : System.Web.Mvc.ViewUserControl<MyUserControlViewData> {
}

public class MyUserControlViewData {
    public IList<MyData> MyData { get; set; }
    public string SomethingElse { get; set; }
}

After that you can create an instance of MyUserControlViewData classin your controller, populate with data and pass it to the view. Is that what you're looking for?

Answer 2

You can use the RenderAction HtmlHelper, found in the MVC futures dll available at codeplex. In your main page ... <% Html.RenderAction("actionName", "controllerName", new {showTitle=true, row=ViewData.Model.Row}); %>

You need an action method on the controller with the parameters. The action then creates a ViewData for the usercontrol. The usercontrol is returned as a view with

return View("usercontrolname", model);

The .ascx file then uses the model for just the user control. The resulting HTML is rendered into the calling page.
