telerik - Export multiple hidden columns for Kendo grid -


here code exporting multiple hidden columns kendo grid, 

var exportflag = false; $("#grid").data("kendogrid").bind("excelexport", function (e) { if (!exportflag) {         e.sender.showcolumn(0);         e.preventdefault();         exportflag = true;         settimeout(function () {             e.sender.saveasexcel();        });     } else {         e.sender.hidecolumn(0);        exportflag = false;     } });

in above code there given e.sender.showcolumn(0); , need export nth number of columns (export multiple hidden columns) this: e.sender.showcolumn(n);.

how possible?

you can have array of hidden columns. iterate columns , if index in array show it.

function isinarray(value, array) {                 return array.indexof(value) > -1;             }  var hidencoll = [1, 2, 3, 4]; // hidden cols indexes  for(i=0; i< grid.columns.length; i++)             {                 if (isinarray(i,hidencoll))                     grid.showcolumn(i); // grid.hidecolumn(i);                            }

or if want first n columns: 

  for(i=0; i< grid.columns.length; i++)         {            if (i <= n)                  grid.showcolumn(i); // grid.hidecolumn(i);                        }

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
