Question

I habe some problems with setting the header for my worksheet 2

Here is my code:

            Excel.Application xlApp1 = new Excel.Application();
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet1 = new Excel.Worksheet();
            Excel.Worksheet xlWorkSheet2 = new Excel.Worksheet();
            object misValue = System.Reflection.Missing.Value;

            xlWorkBook = xlApp1.Workbooks.Add(misValue);
            xlWorkSheet1 = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); // Sheet1
            xlWorkSheet1.Name = "XX";
            xlWorkSheet2 = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2); // Sheet2
            xlWorkSheet2.Name = "YY";

            Excel.Range headerRange = xlApp1.get_Range("A1", "V1");
            headerRange.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;

            for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
            {

                xlApp1.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;

            }

Should I make new Excel Application for new header for Worksheet 2? but i doesn’t make any sense. Can anyone help me with it? thanks you guys…

You can write to any cell you want, including the header cells. Just choose the worksheet in which you want to insert the header.

Excel.Range headerRange = xlWorkSheet1.get_Range("A1", "V1");
headerRange.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
headerRange.Value = "Header text 1";

headerRange = xlWorkSheet2.get_Range("A1", "V1");
headerRange.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
headerRange.Value = "Header text 2";
