Getting Started

This article will get you started in using the RadSpreadProcessing library. It contains the following sections:

Assembly References

In order to use the model of the RadSpreadProcessing library in your project, you need to add references to the following assemblies:

  • Telerik.Windows.Documents.Core.dll
  • Telerik.Windows.Documents.Spreadsheet.dll

The following assemblies are required in order to be able to export to Xlsx and PDF formats:

  • Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.dll
  • Telerik.Windows.Documents.Fixed.dll
  • Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.dll

To describe different colors, shapes and other properties, RadSpreadProcessing depends on the listed below .NET assemblies, which you should also refer in your project:

  • WindowsBase.dll
  • PresentationCore.dll
  • PresentationFramework.dll

Creating a Workbook

The document model allows you to instantiate a new workbook and populate it with any data you want.

Example 1 shows how you can create a workbook and add a new worksheet to it.

Example 1: Create Workbook

Workbook workbook = new Workbook(); 
Worksheet worksheet = workbook.Worksheets.Add(); 

You can then create a CellSelection and set any value to the selected cells. Example 2 shows how you can create a cell and set a string value to it.

Example 2: Set value of cell

CellSelection selection = worksheet.Cells[1, 1]; //B2 cell 
selection.SetValue("Hello RadSpreadProcessing"); 


The RadSpreadProcessing library supports a variety of formats to which you can export the contents of a workbook. Example 3 shows how you can export the previously created workbook to Xlsx format.

Example 3: Export to Xlsx

string fileName = "SampleFile.xlsx"; 
IWorkbookFormatProvider formatProvider = new XlsxFormatProvider(); 
using (Stream output = new FileStream(fileName, FileMode.Create)) 
    formatProvider.Export(workbook, output); 

More information about the import and export functionalities of RadSpreadProcessing is available in the Formats and Conversion section.
