asp.net - GridView to Excel using EPPlus -


i'm trying create excel sheet using epplus's library. however, output excel file not relate cells of representing numbers.

enter image description here

the code i'm using is:

using (var pck = new excelpackage()) {     excelworksheet ws = pck.workbook.worksheets.add(string.isnullorempty(spreadsheetname) ? "report" : spreadsheetname);     ws.cells["b2"].loadfromdatatable(gridviewtable, true, officeopenxml.table.tablestyles.light1);      (int = 1; <= gridviewtable.columns.count; i++)     {         ws.column(i).autofit();     }      // **************     //     header     // **************      //prepare range column headers     string cellrange = "b2:" + convert.tochar('b' + gridviewtable.columns.count - 1) + 2;      //format header columns     using (excelrange rng = ws.cells[cellrange])     {         rng.style.wraptext = false;         rng.style.horizontalalignment = excelhorizontalalignment.center;         rng.style.font.bold = true;         rng.style.fill.patterntype = excelfillstyle.solid; //set pattern background solid         rng.style.fill.backgroundcolor.setcolor(colortranslator.fromhtml("#007a99"));         rng.style.font.color.setcolor(color.white);     }      // ************     //     data     // ************      //prepare range rows     string rowscellrange = "b3:" + convert.tochar('b' + gridviewtable.columns.count - 1) + (gridviewtable.rows.count + 1);      //format rows     using (excelrange rng = ws.cells[rowscellrange])     {         rng.style.wraptext = false;         rng.style.horizontalalignment = excelhorizontalalignment.left;         rng.style.fill.patterntype = excelfillstyle.solid; //set pattern background solid         rng.style.fill.backgroundcolor.setcolor(colortranslator.fromhtml("#b2d1f0"));         rng.style.font.color.setcolor(color.black);     }      response.clearheaders();     response.clearcontent();     response.contenttype = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";     response.addheader("content-disposition", "attachment; filename=" + (string.isnullorempty(filename) ? "report" : filename) + ".xlsx");     response.binarywrite(pck.getasbytearray()); }

does might know why happening ?

i got it.

if use loadfromdatatable() method, datatable object should typed in columns, meaning should create columns using table.columns.add(columnname, columntype);

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
