c# - Disable paging in GridView to Excel export -

-

i've got function export data gridview excel, bound checkboxes. exports rows checked. works fine, can't seem disable paging export? code:

 private void exportgridtoexcel() {      bool isselected = false;     foreach (gridviewrow in gridview1.rows)     {         checkbox cb = (checkbox)i.findcontrol("chkselect");         if (cb != null && cb.checked)         {             isselected = true;             break;         }     }      if (isselected)     {         gridview gvexport = gridview1;         // below line not export checkbox excel file         gvexport.columns[0].visible = false;         foreach (gridviewrow in gridview1.rows)         {             gvexport.rows[i.rowindex].visible = false;             checkbox cb = (checkbox)i.findcontrol("chkselect");             if (cb != null && cb.checked)             {                 gvexport.rows[i.rowindex].visible = true;             }         }          response.clear();         response.buffer = true;         response.addheader("content-disposition", "attachment;filename=exportgriddata.xls");         response.charset = "";         response.contenttype = "application/vnd.ms-excel";         stringwriter sw = new stringwriter();         htmltextwriter htw = new htmltextwriter(sw);         response.contentencoding = system.text.encoding.unicode;         response.binarywrite(system.text.encoding.unicode.getpreamble());         response.cache.setcacheability(httpcacheability.nocache);         gvexport.allowpaging = false;         gvexport.rendercontrol(htw);         response.output.write(sw.tostring());         response.end();      } }  protected void button3_click(object sender, eventargs e) {      exportgridtoexcel();  }

as can see i've set allowpaging = false page numbers still visible in exported file. got idea why?

to export whole data gridview have re-bind datasource

//1.bind paging disabled gvexport.allowpaging = false; gvexport.databind();  //2.export method here  //3.bind paging enabled gvexport.allowpaging = true; gvexport.databind();

but if it's possible export data directly datasource because have remove headers, hide columns, replace   , handle controls asp:checkbox seperately

this approach if want export asop:gridview - http://forums.asp.net/post/4222334.aspx

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
