Hi,

I have partial view

@inherits Umbraco.Web.Mvc.UmbracoViewPage<UmbracoMVC0.Models.CommentViewModel>

@using Umbraco.Web.Mvc
@using UmbracoMVC1.Controllers
@using Umbraco.Web

@Model UmbracoMVC0.Models.CommentViewModel

@using (Html.BeginUmbracoForm<BlogPostSurfaceController>("CreateComment"))
{
    @Html.EditorFor(x => Model)
    <input type="submit" />
}

When I run it I get runtime error

Umbraco.Web.Mvc.ModelBindingException: 'Cannot bind source type Umbraco.Web.Models.RenderModel`1[[Umbraco.Web.PublishedContentModels.Home, AppWeball.generated.cs.8f9494c4.moxirk3w, Version=0.0.0.1, Culture=neutral, PublicKeyToken=null]] to model type UmbracoMVC0.Models.CommentViewModel.'

the model is:

public class CommentViewModel
    {
        //[Required]
        public string Name { get; set; }

        //[Required]
        public string Email { get; set; }

        //[Required]
        [Display(Name = "Enter a comment")]
        public string Comment { get; set; }

         }

How do I make this work? please advice

Hi Sonja

It looks like you are running this code on a Home page. So you have to use "Umbraco.Web.PublishedContentModels.Home" as a model:
```
@inherits Umbraco.Web.Mvc.UmbracoViewPage<Umbraco.Web.PublishedContentModels.Home> 
```

Hi Sonja,

How are you calling your partial view?

Thanks,

Nik

You are welcome, Sonja. You can use CommentViewModel of course, but you have to pass a model of CommentViewModel type to your partial. Do not use Umbraco helper for rendering partial view.

Alex I've tried this in the partial view

@using UmbracoMVC0.Controllers
@using Umbraco.Web

@Model UmbracoMVC0.Models.CommentViewModel

@using (Html.BeginUmbracoForm<BlogPostSurfaceController>("CreateComment"))
{
    @Html.EditorFor(x => Model)
    <input type="submit" />
}

and I'm getting displayed on the web page

Umbraco.Web.Models.RenderModel`1[Umbraco.Web.PublishedContentModels.Home] UmbracoMVC0.Models.CommentViewModel CurrentCulture

and there is a textbox with en-us and button Submit Query and when I press the button I'm getting

  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.

Can you please tell me where shall i define this missing parmeter

Hi Sonja,

Try this way to call partial:
```
<section >
    @Html.Partial("BlogCommentForm", new CommentViewModel())
</section>
```

The model name displayed twice I solved this with removing @Model UmbracoMVC0.Models.CommentViewModel

now it is ok. Thanks
