Hello Telerik support team,

 

I have an ASP.NET MVC project made in .NET Framework 4.6.2

It is using a local directory with files of version 2022.2.510 of Kendo UI. These are the contents of /lib/KENDOUIMVC/2022.2.510.545 of my project:

Kendo.Mvc.dll*  cs-CZ/            el-GR/   fr-FR/  pl-PL/  ru-RU/        tr-TR/
Kendo.Mvc.xml   da-DK/            es-ES/   he-IL/  pt-BR/  sk-SK/        uk-UA/
ar-AE/          de-DE/            export/  it-IT/  pt-PT/  spreadsheet/  zh-CN/
bg-BG/          distribution.xml  fr-CA/   nl-NL/  ro-RO/  sv-SE/

 

I want to make use of the DropDownButton component in this project, and I tried the example code from this page:

https://demos.telerik.com/aspnet-mvc/dropdownbutton

I get this error however:

'WidgetFactory<InvoiceFilterViewModel>' does not contain a definition for 'DropDownButton' and no accessible extension method 'DropDownButton' accepting a first argument of type 'WidgetFactory<InvoiceFilterViewModel>' could be found (are you missing a using directive or an assembly reference?)

So I believe the DropDownButton is not available yet in the version of Kendo that I am using.

 

My questions;

1. Is it possible to upgrade my version of Kendo in the same way as have already? I tried looking in the downloads section, but I don't see the bundle of files I need. The source code bundles contain many different files. If this is not possible, can you then please tell me the alternatives?

2. Is it possible to see which versions a component is supported for on the Telerik documentation website?

 

I already applied an alternative using the DropDownList, but this does not really satisfy the requirements as a DropDownButton would. Note that upgrading the .NET version of this project is (sadly) not a possibility for me at the moment.

 

And a little side note, it seems this link is broken when clicking on the red "Documentation" button:

Page with the button: https://www.telerik.com/aspnet-mvc/dropdownbutton 

Broken link: https://www.telerik.com/aspnet-mvc/documentation/getting-started

Hello Kevin,

Your assumption is correct - the DropDownButton is introduced in version 2022.2.802.

Indeed, you can upgrade your application to version 2022.2.802 by following the steps in the Upgrade article:

  • Select the version in the DropDown, a per the screenshot below:

  • Download the telerik.ui.for.aspnetmvc.2022.2.802.commercial.zip or 7z archive.
  • You can find the Kendo.Mvc.dll in telerik.ui.for.aspnetmvc.2022.2.802.commercial.7z\wrappers\aspnetmvc\Binaries\Mvc5\ folder. Alternatively, you can download Telerik.UI.for.AspNet.Mvc5.2022.2.802.nupkg and install it through NuGet.
  • Open the "js" directory in the telerik.ui.for.aspnetmvc.2022.2.802.commercial.7z and copy the kendo.all.min.js and kendo.aspnetmvc.min.js files in the Scripts folder in your app.
  • Open the "styles" directory in the telerik.ui.for.aspnetmvc.2022.2.802.commercial.7z and copy the desired Kendo UI theme in the Content folder in your app. For more information on how to access the client-side resources, refer to the Using Local files article.
  • Update the Kendo UI scripts and theme file references in the _Layout.cshtml file:
<link href="~/Content/kendo.default-v2.min.css" rel="stylesheet" />
<script src="~/Scripts/jquery-3.6.0.js"></script>
<script src="~/Scripts/kendo.all.min.js"></script>
<script src="~/Scripts/kendo.aspnetmvc.min.js"></script>

Alternatively, you can reference the scripts and stylesheet through the CDN.

It is imporatant to ensure that the versions of the Kendo.Mvc.dll and the required client-side resources (scripts and theme file) are identical.

Finally, thank you for reporting that the link to the DropDownButton documentation is borken. It is greatly appreciated!  Here is the correct link for your reference:
