Telerik Nuget is Missing Telerik.Web.Spreadsheet Framework

[Caleb]

We switched from using your DLLs directly to pulling from Nuget.

We were originally targeting the .NET Framework version of your libraries and planned to continue to do so.

However in the conversion it was realized that Telerik.Web.Spreadsheet is only available as Standard in your Nuget. Therefore due to this ONE missing library I had to convert everything to Standard.

This was fine until we realized that Standard isn't capable of embedding subset fonts into PDFs like Framework, leading to larger files.

I attempted to do a mix of the two and failed but I'd really rather not do that anyway.

Could you please properly update your Nuget to include the Framework version of Telerik.Web.Spreadsheet? I know it exists because I used it before moving to Nuget.

Thank you

Hi Caleb,

Telerik.Web.Spreadsheet is a .NET Framework library and it is required by RadSpreadsheet (ASP.NET WebForms Control) to work.

We have the same assembly for the Telerik UI for ASP.NET AJAX Installers or in the NuGet package repository.

• First Steps with Telerik AJAX (MSI)
• First Steps with Telerik AJAX (ZIP)
• First Steps with Telerik AJAX (NuGet)

 

Are you trying to use the RadSpreadsheet component and you are unable to or are you trying to create/manipulate documents?

For manipulating documents, there are separate .NET libraries called the Telerik Document Processing Libraries. One of its libraries is called the RadSpreadProcessing library.

Can you please clarify your intention and the issue that you are experiencing?

I am trying to do both. But the issue comes with using RadSpreadsheet.

On this page: https://docs.telerik.com/devtools/aspnet-ajax/controls/spreadsheet/getting-started

In the Assembly section it says:

"You can access the needed assemblies from the AdditionalLibraries folder in the Telerik® UI for ASP.NET AJAX installation (automated and manual) and from the internal builds archive. They support .NET 4 and .NET 4.5, so depending on the target framework of your project, you need to take the assemblies from the Bin40 or the Bin45 folder respectively."

However this is not true for Nuget installation. The correct Telerik.Web.Spreadsheet.dll is missing from Nuget. This dll is NOT included in Telerik.UI.for.AspNet.Ajax.Net45.

I have all of the libraries on that page except Telerik.Web.Spreadsheet. My code for creating a Telerik.Web.Spreadsheet.Workbook of course throws a compilation error stating that I need the Telerik.Web.Spreadsheet library. However if you go to the Telerik Nuget right now and lookup Telerik.Web.Spreadsheet you will only find the Standard version. If I attempt to install that then it wants to install all of its dependencies which are the various Telerik.Documents... assemblies. NOT Telerik.Windows.Documents... as stated in the article. Because Telerik.Documents is the Standard version of Telerik.Windows.Documents.  And if you were to install the available Telerik.Web.Spreadsheet you will see that under lib there is only 1 folder: "netstandard2.0". Unlike some libraries where there are many folders for standard, framework, core, etc.

Unless there is some other Telerik package hidden somewhere which includes Framework Telerik.Web.Spreadsheet?

Hi Caleb,

Thanks for clarifying the issue, now I see where the problem is.

The Telerik.Web.Spreadsheet.dll was added to NuGet with recent versions of Telerik. If you do not see that, you are likely using an old version. In that case, you would need to reference this assembly manually.

 

I have tested the current version (2022.3.913) and the assembly is available, see the screenshot below:

 

UPDATE

The Telerik.Web.Spreadsheet.dll is part of the Kendo suite, and since the Telerik RadSpreadsheet for ASP.NET AJAX is actually a wrapper for the Kendo widget, we need to include the assembly in the Telerik UI for ASP.NET AJAX suite. 

Until recently we have shipped the Assembly in the AdditionalLibraries folder. Current versions of NuGet packages now include it and will be available as per the screenshot above.

 

You are correct that the Telerik.Web.Spreadsheet.dll is a .NET Standard 2.0 but is compatible with both .NET Core and .NET 4.6.1+ and this shall be used.

For more details, you can check out the Differences Between .NET Framework, .NET Core, and .NET Standard article.

This is not true.

The Standard version of Telerik.Web.Spreadsheet (on Nuget, the one you mention) depends on namespace Telerik.Documents...

The Framework version of Telerik.Web.Spreadsheet (not on Nuget) depends on namespace Telerik.Windows.Documents...

IF you try to use Standard Telerik.Web.Spreadsheet with Telerik.Windows.Documents... it will not compile.

I've decided to stop fooling with this and just include the Framework Telerik.Web.Spreadsheet.dll in my project files for reference to "solve" this problem. 

Thanks

Update

In further testing it looks like the Standard actually ends up with a smaller size anyway so I'll keep that. I think the only way I'll get them even smaller is a different library.

Caleb, 

There's a single assembly file "Telerik.Web.Spreadsheet.dll" and it is used across multiple suites (Telerik UI for ASP.NET AJAX, Telerik UI for .NET MVC, and Telerik  UI for .NET Core).

The namespace "Telerik.Documents.Common.Model" will only be set as a dependency if the Telerik.Web.Spreadsheet.dll is used in an application that targets the .NET Standard (2.0).

For applications targeting the .NET Framework 4.0 and above, the "Telerik.Windows.Documents.Spreadsheet.Theming" namespace is used.

I hope this will clarify the confusion.
