I can filter a date column in my datagridview but when i try to export it to excel it exports the whole datatable and not the filtered Datagridview.

These are part of what i have done so far

Filtering for the Date column which works

C#

private void BtnFilter_Click(object sender, EventArgs e)
       {
           bSource = new BindingSource();
           bSource.DataSource = eTable;
           dgv1.DataSource = bSource;
           bSource.Filter = string.Format("DateTime>= '{0:dd/MM/yyyy}' AND      DateTime <= '{1:dd/MM/yyyy}'", dtPickerStart.Value.Date, dtPickerStop.Value.Date);

Export event that exports whole datatable and not the filtered datagridview

C#

}
                    using (ExcelPackage pck = new ExcelPackage(file))
                   {
                       bSource = new BindingSource();
                       bSource.DataSource = dgv1;
                       dgv1.DataSource = eTable;

                       ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Sheet1");
                       ws.Cells["A1"].LoadFromDataTable(((System.Data.DataTable)dgv1.DataSource), true, OfficeOpenXml.Table.TableStyles.Light1);

I suspect that i am not using the bindingsource correctly.Any suggestions would be appreciated

I found the solution on another site.I had to make use of the DataTable.DefaultView property to export the filtered datagridview.

This is the code to export the filterd datagridview

C#

using (ExcelPackage pck = new ExcelPackage(file))
                   {
                       BindingSource bs = (BindingSource)dgv1.DataSource;
                       System.Data.DataTable table = (System.Data.DataTable)bs.DataSource;
                       System.Data.DataTable filtered = table.DefaultView.ToTable();

                       ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Sheet1");
                       ws.Cells["A1"].LoadFromDataTable(((System.Data.DataTable)filtered), true, OfficeOpenXml.Table.TableStyles.Light1);
                       using (ExcelRange rng = ws.Cells[1, 1, 1, dgv1.Columns.Count])
                       {
                           rng.Style.Font.Bold = true;
                           rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
                           rng.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.FromArgb(79, 129, 189));
                           rng.Style.Font.Color.SetColor(System.Drawing.Color.White);

                           ws.Column(3).Hidden = false;
                           ws.Cells["A1"].AutoFitColumns(25);
                           ws.Cells["B1"].Value = "Employee Number";
                           ws.Cells["B1"].AutoFitColumns(40);
                           ws.Cells["B1"].Value = "Employee Number";
                           ws.Cells["D1"].AutoFitColumns(60);
                           ws.Column(4).Style.Numberformat.Format = "dd/MM/yyyy";
                       }

                       pck.Save();
                   }
