How to retrieve cell value without enabling sheet calculations in C#, VB.NET?
This article explains how to retrieve the cell value without enabling sheet calculations using XlsIO.
There can be situations where the formula value or the last calculated value in a cell is required without actually recalculating sheet formulas through EnableSheetCalculations. This can be achieved using the DisplayText property in the worksheet range.
The below table illustrates the behavior of the DisplayText property with respect to enabling sheet calculations.
| DisplayText while opening an existing workbook | DisplayText while creating a new workbook |
Without EnableSheetCalculation | Always returns the cell value with its number format. | Returns 0, if the cell has a formula Returns cell value with number format, if cell does not have formula |
With EnableSheetCalculation | Returns the evaluated value with number format, if the cell has a formula. Returns cell value with number format, if cell does not have formula | Returns evaluated value with number format, if cell has a formula

Code snippet to use DisplayText property
//Retrieving display text of the cell string displayText = worksheet.Range["C2"].DisplayText;

The following complete code snippet explains how to retrieve the formula value in a cell without enabling sheet calculations using XlsIO.
C#
using Syncfusion.XlsIO;
using System.IO;
using System.Reflection;
namespace FormulaValue
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
// Opening existing workbook with named range
Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
Stream inputStream = assembly.GetManifestResourceStream("FormulaValue.Sample.xlsx");
IWorkbook workbook = application.Workbooks.Open(inputStream);
IWorksheet worksheet = workbook.Worksheets[0];
// Retrieving formula in the cell using Formula
string formula = worksheet.Range["C2"].Formula;
// Retrieving display text of the cell
string displayText = worksheet.Range["C2"].DisplayText;
// Saving the workbook as stream
Stream outputStream = File.Create("Output.xlsx");
workbook.SaveAs(outputStream);
}
}
}
}VB
