Hi,

Spreadsheet is working fine on our evaluation server, but not is production server.

I think that it might be missing a dll file. What dll files are needed?

Hello Mikko,

The required assemblies for the Spreadsheet are listed in the Spreadsheet Getting Started article:

In order to use the RadSpreadsheet control in your project you need to add references to the following assemblies:

  • Telerik.Web.Spreadsheet.dll
  • Newtonsoft.Json.dll

You can find the needed assemblies in the AdditionalLibraries folder in the Telerik® UI for ASP.NET AJAX installation (automated and manual) and in 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 Bin45 folder respectively.

The following assemblies are required in order to be able to use the control with the predefined SpreadsheetDocumentProvider (applicable for most scenarios):

  • Telerik.Windows.Documents.Core.dll — the main assembly from the Telerik document processing libraries.
  • Telerik.Windows.Zip.dll — needed for working with zipped formats (DOCX, XLSX) and PDF.
  • Telerik.Windows.Documents.Spreadsheet.dll — the main assembly for the spreadsheet processing. It is needed for processing XLSX, CSV, TXT documents.
  • Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.dll — needed for processing XLSX documents.

You could find the above assemblies in the AdditionalLibraries folder of the installation directory on your machine (C:\Program Files\Progress\UI for ASP.NET AJAX RX YYYY).
