protected void AddDropDownToExcel(string path) 
     { 
      //path gives the location where u have created excel file 
      string fileName = path.Replace("\\", "\\\\"); 
// F is the column name where you want to place the dropdown 
      string RowCount = "F" + gridrowcount; 
      // Open Excel and get first worksheet.  
      var workbook = application.Workbooks.Open(fileName); 
      var worksheet = workbook.Worksheets[1] as Microsoft.Office.Interop.Excel.Worksheet;  
      // Set range for dropdownlist  
      var rangeNewStatus = worksheet.get_Range("F2", RowCount); 
      rangeNewStatus.ColumnWidth = 20; 
      rangeNewStatus.Validation.Add(Microsoft.Office.Interop.Excel.XlDVType.xlValidateList, Microsoft.Office.Interop.Excel.XlDVAlertStyle.xlValidAlertStop, 
      Microsoft.Office.Interop.Excel.XlFormatConditionOperator.xlBetween, "dropdownlistitem1, dropdownlistitem2"); 
      // Save. 
      workbook.Save(); 
      workbook.Close(Microsoft.Office.Interop.Excel.XlSaveAction.xlSaveChanges, Type.Missing, Type.Missing); 
      application.Quit(); 
     }
