Older App using Telerik Rad Controls - how to upgrade

[Mark]

Hello,  

I am new to a team of developers and one of our tasks is maintaining an older website that uses Telerik Rad controls.

I would like to identify if we need to upgrade the existing controls for security patches etc.

What is best way to determine what version of controls we have and how to update them if necessary ?

 

Thanks

Hi Mark,

There are three easy ways to check the version of the Telerik.Web.UI.dll assembly, which is the main file of the Telerik ASP.NET AJAX suite:

For ASP.NET WebApplication types of projects, open the csproj file and search for “Telerik.Web.UI” - the path in the HintPath will show you the location of the Telerik.Web.UI.dll file

<Reference Include="Telerik.Web.UI">
          <HintPath>\bin\Telerik.Web.UI.dll</HintPath>
         …
</Reference>

Once you have the path from the HintPath, navigate to the Telerik.Web.UI.dll in Windows Explorer, right-click, choose Properties -> Description tab and find out the version in the File Version row:

 

For ASP.NET WebSite types of projects, go to the bin folder of the web project and right-click on the Telerik.Web.UI.dll -> Properties -> Description -> see the version in the File version line.

Inspect the version in the GAC as explained in the Referencing Assemblies from the GAC article

Our recommendation is to upgrade to the latest available version of the Telerik AJAX suite which is currently 2021.1.616 (R2 2021 SP1). 

You can find more information at:
