Hi Members,
I have export my gridview data to excel using EPPLUS, but however for a few columns I have this green tag "Number Stored as Text" prompt after opening the excel file that was exported.
How can I code in my export to excel codes to change the datatype/convert to number for a specific column starting from the 2nd row of a specified column since the 1st row is header?
The below is my export codes:
protected void EXPORT_BUTTON_Click(object sender, EventArgs e)
{
ExcelPackage package = new ExcelPackage();
ExcelWorksheet Grid = package.Workbook.Worksheets.Add("ORSA ASSESSMENTS");
DataTable Gridview1 = new DataTable();
for (int i = 0; i < Gridview1.Columns.Count; i++)
{
Gridview1.Columns.Add("column" + i.ToString());
}
foreach (GridViewRow row in Gridview1.Rows)
{
DataRow dr = Gridview1.NewRow();
for (int j = 0; j < Gridview1.Columns.Count; j++)
{
row.Cells[j].Text = row.Cells[j].Text.Replace(" ", " ");
dr["column" + j.ToString()] = row.Cells[j].Text;
}
Gridview1.Rows.Add(dr);
}
Grid.Cells["A1"].LoadFromDataTable(Gridview1, true);
using (ExcelRange rng = Grid.Cells["A1:Z1"])
{
rng.Style.Font.Bold = true;
}
Grid.Cells[ORSA.Dimension.Address].AutoFitColumns();
var FolderPath = ServerName + DirectoryLocation + DirectoryFolder + ExportsFolder;
var filename = ExcelName + @"_" + ".xlsx";
var filepath = new FileInfo(Path.Combine(FolderPath, filename));
Response.Clear();
package.SaveAs(filepath);
Response.AddHeader("content-disposition", "attachment; filename=" + filename + ";");
Response.Charset = "";
Response.ContentType = "application/vnd.xlsx";
Response.TransmitFile(filepath.FullName);
Response.End();
}
