I am attempting to build a sample application, by converting parts of the Telerik Demo Website to Razor syntax. The issue is that the content appears out of order at the top.

By the way, I have had this issue even when using a single component such as Grid on ASP.Net MVC3.

I am attaching a screenshot and zip file of my entire project. Simply start the project to see the issue. Thanks.

Here is the HTML output of my index view on home controller:

<link type="text/css" href="/Content/telerik.examples.min.css" 
rel="stylesheet"/><BR><link type="text/css"

    @{ Html.Telerik().StyleSheetRegistrar()
                      .DefaultGroup(group => group
                          .Add("telerik.examples.css")
                          .Add("telerik.common.css")
                          .Add("telerik." + Html.GetCurrentTheme() + ".css")
                          .Add("telerik.rtl.css")
                          .Combined(false)
                          .Compress(false)).Render();
                     }
    @{Html.Partial("Header"); }

<body>
    <div id="page">

        @{ Html.Partial("Navigation");}
        @{ Html.Partial("Resources");}
        @{ Html.Partial("ProductLines");}

    @{ Html.Telerik().ScriptRegistrar()

Do you know if it is possible to get the source code for the converted app http://mvcdemo.chiplex.com

Yes, source code or a fix would be helpful. I'm having the same problem, and need to get it resolved as it is causing problems with IE (DOCTYPE needs to be the first thing in the document for it to properly handle it)

There are no issues with using Telerik with MVC3 (I have tested with latest RC). I am not a Telerik employee, but I can certainly say that as quickly as the ASP.Net group has been releasing updates for MVC3 (we are to RC2 already, with the final promised in mid-January) it is a challenge to keep up the pace.   It's been less than a year since MVC2 was released!

I will convert the "_Layout.cshml" example shown above:

<!DOCTYPE html>
<html>
<head>
    <title>@View.Title</title>
    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
    @( Html.Telerik().StyleSheetRegistrar()
                      .DefaultGroup(group => group
                          .Add("telerik.examples.css")
                          .Add("telerik.common.css")
                          .Add("telerik." + Html.GetCurrentTheme() + ".css")
                          .Add("telerik.rtl.css")
                          .Combined(false)
                          .Compress(false)))
 
    @Html.Partial("Header")
</head>
<body>
    <div id="page">
        <h1 id="title">
            @Html.ActionLink("Telerik Extensions for ASP.NET MVC", "FirstLook", "Home")
        </h1>
        <div id="main">
            @RenderBody()
        </div>
        @Html.Partial("Navigation")
        @Html.Partial("Resources")
        @Html.Partial("ProductLines")
        @Html.Partial("Footer")
    </div>
 
    @( Html.Telerik().ScriptRegistrar()
                     .DefaultGroup(group => group
                         .Add("telerik.examples.js")
                         .Compress(false)))
</body>
</html>

Take some time and look at the changes.  Two big takeaways when converting to Razor syntax:

1)  Use  @(   ....   )  when outputting html,  not  @{   ....  ;}
     - wrap the code for Telerik controls in parentheses, not brackets
     - using brackets, you're essentially telling Razor to execute a method. You won't get any output
2)  Remove the ".Render()" method for any Telerik controls.  Not used in Razor.

You will need to do the same thing for each partial that is listed in the sample.   Once done, all your content will be in its rightful place.   I downloaded the zip file above and verified the steps.  NOTE:  "View" becomes "ViewBag" in MVC3 RC2.

Hope the information helps!

Hi @Mike Kidder

Could you tell me how to make telerik run with ASP.NET MVC 3 RC2? because I have not been able to. BTW, I have the Q3 version (v2010.3.1110.235)

I have followed the instruction manual but unfortunately it throws an exception. The compiler error tells me:

"'System.Web.Mvc.HtmlHelper<dynamic>' does not contain a definition for 'Telerik' and no extension method 'Telerik' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<dynamic>' could be found (are you missing a using directive or an assembly reference?)"

I have made a reference on my project to the Telerik.Web.Mvc.dll assembly (which was located on the MVC 2 folder: Telerik\Extensions for ASP.NET MVC Q3 2010\Binaries\MVC2).

The web.config file has the line:
<add namespace="Telerik.Web.Mvc.UI" />

Any clue?

best regards

I again

Answering myself, I didn't reallize that I had to paste the reference to the assembly <add namespace="Telerik.Web.Mvc.UI" /> on the inner web.config file, which by the way is inside the <system.web.webPages.razor> sectionGroup.

Best regards
