Answer 1

Let ASP.NET MVC know of the Kendo.Mvc.UI namespace where the server-side wrappers are. To do this, update the web.config file of the web application.

Step 1 Open Views/Web.config, or root Web.config if using ASPX.

Step 2 Locate the namespaces tag.

Step 3 Append an add tag to the namespaces tag.

EXAMPLE

<namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Routing" />
    <add namespace="Kendo.Mvc.UI" />
</namespaces>

Step 4 Add a binding redirect to your current System.Web.Mvc version.

EXAMPLE

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-[version-of-kendo-dll-that-you-are-using]" newVersion="[version-of-kendo-dll-that-you-are-using]" />
</dependentAssembly>

I have done all those steps but its still not working – Boxhaul

Try adding @using Kendo.Mvc.UI in the _ViewStart.cshtml file inside the Views folder – Ial

Also check if the namespace is added in the web.config inside the Views folder and not in the web.config of the root folder – Ial

I have added in controller class using Kendo.Mvc.Extensions; using Kendo.Mvc.UI; and is recognizing but it still not working in razor view pages for some of reason – Boxhaul

have you tried and checked by adding in the _ViewStart.cshtml file? – Ial

many thanks, I have added references in _ViewStart.cshtml and it works – Boxhaul

For me, it still didn't work until I built the project and restarted the solution. – Candlewick
