4 mins read

Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Also, converts Excel documents to PDF files. Using this library, you can load data from Excel to DataGrid or DataGridView in C#.

Using XlsIO, data can be loaded from Excel to DataGrid or DataGridView in the following ways:

Steps to load data from Excel to DataGrid or DataGridView, programmatically:

Step 4: Include the following namespaces in the Form1.cs file.


using Syncfusion.XlsIO;



Imports Syncfusion.XlsIO


Step 5: Add a below code in Form1.Designer.cs file for new button.


private DataGrid dataGrid;
private Button btnImport;
private Label label;
private void InitializeComponent()
  btnImport = new Button();
  dataGrid = new DataGrid();
  label = new Label();
  btnImport.Location = new System.Drawing.Point(41, 404);
  btnImport.Size = new System.Drawing.Size(280, 23);
  btnImport.Text = "Load Excel to DataGrid";
  btnImport.Click += new EventHandler(btnImport_Click);
  label.Location = new System.Drawing.Point(0, 50);
  label.Size = new System.Drawing.Size(426, 48);
  label.Text = "Click the button to load Excel spreadsheet to DataGrid through Essential XlsIO.";
  label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
  dataGrid.Location = new System.Drawing.Point(29, 96);
  dataGrid.Size = new System.Drawing.Size(312, 292);
  //Excel to DataGrid 
  ClientSize = new System.Drawing.Size(425, 434);
  Text = "Load DataGrid";



Private WithEvents label As Label
Private WithEvents btnImport As Button
Private WithEvents dataGrid As DataGrid
Private Sub InitializeComponent()
  label = New Label()
  btnImport = New Button()
  dataGrid = New DataGrid()
  btnImport.Location = New Point(41, 404)
  btnImport.Size = New Size(280, 23)
  btnImport.Text = "Load Excel to DataGrid"
  AddHandler btnImport.Click, AddressOf Me.btnImport_Click
  label.Location = New Point(0, 50)
  label.Size = New Size(426, 48)
  label.Text = "Click the button to load Excel spreadsheet to DataGrid through Essential XlsIO."
  label.TextAlign = ContentAlignment.MiddleCenter
  dataGrid.Location = New Point(29, 96)
  dataGrid.Size = New Size(312, 292)
  'Excel to DataGrid
  ClientSize = New Size(425, 434)
  Text = "Load DataGrid"
End Sub


Step 6: Data in the Excel worksheet can be exported to a DataTable using ExportDataTable() method. This data table can be assigned as source to data grid. Add the below complete code in button click event in Form1.cs file to export data from Excel worksheet to DataGrid.


//Initialize the Excel Engine
using (ExcelEngine excelEngine = new ExcelEngine())
  //Initialize Application
  IApplication application = excelEngine.Excel;
  //Set default version for application.
  application.DefaultVersion = ExcelVersion.Xlsx;
  //Open existing workbook with data entered
  Assembly assembly = typeof(Form1).GetTypeInfo().Assembly;
  Stream fileStream = assembly.GetManifestResourceStream("ExceltoDataGrid.Sample.xlsx");
  IWorkbook workbook = application.Workbooks.Open(fileStream);
  //Accessing first worksheet in the workbook
  IWorksheet worksheet = workbook.Worksheets[0];
  //Export data from Excel worksheet.
  DataTable customersTable = worksheet.ExportDataTable(worksheet.UsedRange, ExcelExportDataTableOptions.ColumnNames);
  //Load the data to dataGrid
  dataGrid.DataSource = customersTable;
  //No exception will be thrown if there are unsaved workbooks.
  excelEngine.ThrowNotSavedOnDestroy = false;



'Initialize the Excel Engine
Using excelEngine As ExcelEngine = New ExcelEngine()
  'Initialize Application
  Dim application As IApplication = excelEngine.Excel
  'Set default version for application
  application.DefaultVersion = ExcelVersion.Xlsx
  'Open existing workbook with data entered
  Dim assembly As Assembly = GetType(Form1).GetTypeInfo.Assembly
  Dim fileStream As Stream = assembly.GetManifestResourceStream("ExceltoDataGrid.Sample.xlsx")
  Dim workbook As IWorkbook = application.Workbooks.Open(fileStream)
  'Accessing first worksheet in the workbook
  Dim worksheet As IWorksheet = workbook.Worksheets(0)
  'Export data from Excel worksheet
  Dim customersTable As DataTable = worksheet.ExportDataTable(worksheet.UsedRange, ExcelExportDataTableOptions.ColumnNames)
  'Load the data to dataGrid
  DataGrid.DataSource = customersTable
  'No exception will be thrown if there are unsaved workbooks.
  excelEngine.ThrowNotSavedOnDestroy = False
End Using



The input Excel document (Sample.xlsx) should be added in the project and made an Embedded Resource in the Build Action.
