[Solved] "Index was out of range"

[GrZeCh]

Hello,

what should be added to Visual Studio project to make extensions working? For quick test I've added reference to library and added two helpers (DictionaryExtensions.cs and HtmlHelperExtensions.cs) but when I try to open page I'm getting error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

in this lines:

Line 168:            </div>
Line 169:        </div>
Line 170: <% Html.Telerik().Menu()
Line 171:            .Name("Menu")
Line 172:            .HtmlAttributes(new { style = "z-index: 3; position: relative;" })

My menu source:

        <% Html.Telerik().Menu()
            .Name("Menu")
            .HtmlAttributes(new { style = "z-index: 3; position: relative;" })
            .Items(menu =>
            {
                menu.Add()
                    .Text("ASP.NET MVC")
                    .Items(item =>
                    {
                        item.Add().Text("Grid");
                    });
            })
            .Render();
        %>

I've added to controller "ViewData["expandMode"] = "Single";" too but nothing changed.
Any ideas?

Thanks

After adding script registration:

<%
    Html.Telerik().StyleSheetRegistrar()
        .DefaultGroup(group => group.Add("telerik.common.css")
                                    .Add("telerik.vista.css"))
        .Render();
%>

I'm getting this error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

If I remove script registration I'm getting error mentioned on the first post ("Index was out of range....").

Hello,

I've changed in web.config:

    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0" />
                <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35" />
            </dependentAssembly>
            <dependentAssembly xmlns="">
                <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
                <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

to

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

and it started working.
