MVC Model issue can you diagnose what this is saying? - asp.net-mvc

This is part of the first build repoistory that sits on Microsoft MVC.
First call from the controller down for model.
public ActionResult Index()
{
var prog = yRepository.FindUpComingProgrammes();
return View(prog);
}
ASP ERROR:

It sounds like you are using a strongly typed view and the object being passed to the view is not the same that type that the view is bound to...

Umbraco No parameterless constructor defined for this object

I am trying to render a partial view in Umbraco. I have a BaseLayout.cshtml,Homepage.cshtml,BaseLayoutViewModel,HomepageViewModel
This is my BaseLayout View
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.BaseLayoutViewModel>
#{
Layout = null;
}
<!DOCTYPE html>
<html lang="en-gb">
<head>
</head>
<body>
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", Model) //This is there the site throws an error.
#RenderBody()
</body>
</html>
This is my BaseLayout Model. Homepage model inherits from base layout.
public class BaseLayoutViewModel : PublishedContentModel
{
public BaseLayoutViewModel(IPublishedContent content) : base(content)
{
}
public string PageTitle => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageTitle);
public string PageDescription => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageDescription);
public string NavigationName => this.GetPropertyValue<string>(FieldNames.BaseLayout.NavigationName);
}
My PrimaryNavbar Partial view is:
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.PrimaryNavbarViewModel>
<header>
<ul>
<li>
</li
</ul>
</header>
And the controller for the PrimaryNavbar is:
public class PrimaryNavbarController : SurfaceController
{
[ChildActionOnly]
public ActionResult GetPrimaryNavbar(RenderModel model)
{
//var primaryNavbarViewModel = new PrimaryNavbarViewModel(model.Content);
return PartialView("PrimaryNavbar");//, primaryNavbarViewModel);
}
}

I cant understand why I am getting "No parameterless constructor defined for this object." Can someone help me on this?
Thanks
To solve the issue you need to send the model like this:
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", new { model = Model })

Glass.Mapper.MapperException: Failed to create type - No parameterless constructor defined for this object

Following an earlier post, I'm implementing this YouTube Video Picker in Sitecore - this has involved creating a custom Field Type (YouTubeVideoField). the control itself works no problem but when trying to get the video on the page (#Html.Sitecore().Field("YouTube Video")) I get the following error. Any ideas?

EDIT: So I'm reading through the Glass Mapper tutorials - do i need to create a custom data handler?
You probably need to implement a custom data handler. If you want to use the supplied custom field see these examples:

When I try to comment the second rule

</rule>
The site working, but the Layer rule in Widgets not working.
I have try with new installation and the same error occurred.
Even in The Theme Machine without any custom: ASP._Page_Themes_TheThemeMachine_Views_Branding_cshtml
Could you help me to solve this problem?
My scenario is:
I have a main site running on domain.com
And many mini-site running on domain1.com, domain2.com...
All site share the same database, just different by content displayed

Rendering an ActionLink programmatically

I have a scenario where I'd like to render an ActionLink programmatically, ether from a controller or ideally an extension method. This is so I can wrap up some logic of wether to display the link and remove that logic from my view.
I can create an ActionLink using the MVC Futures project from CodePlex.
ActionLink actionLink = new ActionLink();
actionLink.ActionName = "MyActionName";
actionLink.ControllerName = "MyControllerName";
There is a RenderControl method that takes a HtmlTextWriter which I've been trying to use. I can't get this to work and a null reference exception is thrown each time within the Microsoft.Web.Mvc assembly (Futures).
[NullReferenceException: Object reference not set to an instance of an object.]

Any help would be great.
Assuming you're in a controller, you could use the following:
string anchor = HtmlHelper.GenerateLink(
this.Request.RequestContext,
RouteTable.Routes,
"Link name",
"",
"MyActionName",
"MyControllerName",
null,
null);
But I'm not entirely sure what exactly you want to see in the end.
The best way would be store a flag in the model, that's set by the controller, whether to show the link or not, and show/hide it that way. Otherwise, you could look to create your own helper method with this logic; it's essentially rendering an tag, and using the UrlHelper class, the Action method, to generate the url. You could also use UrlHelper in the controller and pass the link through the model too, or in ViewData, etc.
HTH.

On $.Post in Json used in ASP.NET MVC 1.0 i am getting exceed maxlength error

Thank you in advance
You can set it in the web.config for unlimited, the following way:
<Scripting>
<WebServices>
<JsonSerialization MaxJsonLength="0" />
</WebServices>
</Scripting>
The default value is around 4MB.

Here's a very good blog post about it
