How do I create an AutoFilter using XlsIO in WinForms?
Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can create AutoFilter in Excel using C# and VB.NET by specifying the filter range.
The AutoFilter allows a user to filter items in a list according to set criteria. You can filter text, numbers or dates with AutoFilter.
Steps to create AutoFilter in an Excel file programmatically:
Step 1: Create a new C# console application project.
Create a new C# console application
Step 2: Install Syncfusion.XlsIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.
Install NuGet package
Step 3: Include the following namespace in the Program.cs file.
C#
using Syncfusion.XlsIO;
VB.NET
Imports Syncfusion.XlsIO
Step 4: Use the following code snippet to create AutoFilters in an Excel file.
C#
//Create an instance of ExcelEngine
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Set the default application version as Excel 2016
excelEngine.Excel.DefaultVersion = ExcelVersion.Excel2016;
//Create a workbook with a worksheet
//Open existing workbook with data entered
Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
Stream fileStream =
assembly.GetManifestResourceStream("AutoFilters.AutoFilterTemplate.xlsx");
IWorkbook workbook = application.Workbooks.Open(fileStream);
//Access first worksheet from the workbook instance
IWorksheet worksheet = workbook.Worksheets[0];
//Creating an AutoFilter and Specifying the AutoFilter range.
worksheet.AutoFilters.FilterRange = worksheet.Range["A1:B7"];
//Save the workbook to disk in xlsx format
workbook.SaveAs("Output.xlsx");
}
VB.NET
'Create an instance of ExcelEngine
Using excelEngine As ExcelEngine = New ExcelEngine
'Set the default application version as Excel 2016
excelEngine.Excel.DefaultVersion = ExcelVersion.Excel2016
'Open existing workbook with data entered
