I need urgent help. I want to export data from datagrid to Excel but not with datatable. I would like to know if it is possible with datagrid view.
private void buttonAdv1_Click(object sender, EventArgs e)
{
//Exports the DataTable to a spreadsheet.
#region Workbook Initialize
//New instance of XlsIO is created.[Equivalent to launching MS Excel with no workbooks open].
//The instantiation process consists of two steps.
//Step 1 : Instantiate the spreadsheet creation engine.
ExcelEngine excelEngine = new ExcelEngine();
//Step 2 : Instantiate the excel application object.
IApplication application = excelEngine.Excel;
//Set the Workbook version as Excel 97to2003
if (this.rdbExcel97.Checked)
{
application.DefaultVersion = ExcelVersion.Excel97to2003;
fileName = "ExportToExcel.xls";
}
//Set the Workbook version as Excel 2007
else if (this.rdbExcel2007.Checked)
{
application.DefaultVersion = ExcelVersion.Excel2007;
fileName = "ExportToExcel.xlsx";
}
//Set the Workbook version as Excel 2010
else if (this.rdbExcel2010.Checked)
{
application.DefaultVersion = ExcelVersion.Excel2010;
fileName = "ExportToExcel.xlsx";
}
//Set the Workbook version as Excel 2010
else if (this.rdbExcel2013.Checked)
{
application.DefaultVersion = ExcelVersion.Excel2013;
fileName = "ExportToExcel.xlsx";
}
//A new workbook is created.[Equivalent to creating a new workbook in MS Excel]
//The new workbook will have 3 worksheets
IWorkbook workbook = application.Workbooks.Create(1);
//The first worksheet object in the worksheets collection is accessed.
IWorksheet worksheet = workbook.Worksheets[0];
#endregion
#region Export DataTable to Excel
//Export DataTable.
if (this.gridDataBoundGrid1.DataSource != null)
{
worksheet.ImportDataTable((GridDataBoundGrid)this.gridDataBoundGrid1.DataSource, true, 3, 1, -1, -1);
}
else
{
MessageBox.Show("There is no datatable to export, Please import a datatable first", "Error");
//Close the workbook.
workbook.Close();
return;
}
#endregion
#region View the Workbook
//Message box confirmation to view the created spreadsheet.
if (MessageBox.Show("Do you want to view the workbook?", "Workbook has been created",
MessageBoxButtons.YesNo, MessageBoxIcon.Information)
== DialogResult.Yes)
{
//Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
System.Diagnostics.Process.Start(fileName);
//Exit
this.Close();
}
else
{
// Exit
this.Close();
}
