How do I format my export to excel workbook in microsoft.office.interop.excel?

Question

I have this export function that allows me to export 2 grid views into 2 separated worksheets in one excel.

But my problems are:

1. How can I have a usual

Answer 1

as specified by Laxmikant modify the code of your method "ExportToExcel" as follows.

public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook, GridView gridview, string SheetName, int sheetid)
{

// see the excel sheet behind the program
app.Visible = true;

worksheet = (Excel.Worksheet)workbook.Worksheets.Add();

// changing the name of active sheet
worksheet.Name = SheetName;

// storing header part in Excel
for (int i = 1; i < gridview.Columns.Count + 1; i++)
{
    worksheet.Cells[1, i] = gridview.Columns[i - 1].HeaderText;
}

// storing Each row and column value to excel sheet
for (int i = 0; i < gridview.Rows.Count - 1; i++)
{
    for (int j = 0; j < gridview.Columns.Count; j++)
    {
        worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Text.ToString();
    }
}

I removed these two lines of code and now there is no need of the parameter "Sheetid"

Excel.Worksheet worksheet =(Excel.Worksheet)workbook.Worksheets["Sheet" + sheetid];
worksheet = workbook.ActiveSheet;

Hope this will solve your issue
