You should specify that the cell content should be interpreted as dates using setCellFormat() method. It allows to sort dates as 'values' instead of alphabetically.

I use these functions for sorting

/* set data types for column sorting
*/

/* functions which return sortable data */

//strings
function string(text){return text;};          

//numbers
function number(text){return Number(text.replace(/[ ,%$]/gi, '').replace(/\((.*)\)/, '-$1'))}; 

//date/time (dd-mm-yyyy, hh:mm)
function datetime(text){var oData = new Date(); return Number(Date.UTC(text.substr(6, 4),text.substr(3, 2),text.substr(0, 2),text.substr(12, 2),text.substr(15, 2)))}

/* array with column sort types */
var toValue = [number,string,string,date]; //this is for a 4-column grid, column 1 contains numbers, column 4 a date etc

obj.setDataProperty('value', function(i,j){return toValue[j](obj_data[i][j]);});

/* display object on screen */
document.write(obj);


You could use them and rewrite the datetime function (the text.substr.... part)

Good luck

The correct code for above post

/* set data types for column sorting
*/

/* functions which return sortable data */

//strings
function string(text){return text;};          

//numbers
function number(text){return Number(text.replace(/[ ,%$]/gi, '').replace(/\((.*)\)/, '-$1'))}; 

//date/time (dd-mm-yyyy, hh:mm)
function datetime(text){var oData = new Date(); return Number(Date.UTC(text.substr(6, 4),text.substr(3, 2),text.substr(0, 2),text.substr(12, 2),text.substr(15, 2)))}

/* array with column sort types */
var toValue = [number,string,string,datetime]; //this is for a 4-column grid, column 1 contains numbers, column 4 a date etc

obj.setDataProperty('value', function(i,j){return toValue[j](obj_data[i][j]);});

/* display object on screen */
document.write(obj);

You should convert your dates to numbers, as those are sortable. So if you manage to put your dates in the YYYYMMDD format, the sorting works well. Note: the conversion only has to take place before sorting, so the things displayed on the screen can be 08Mar2007 etc.

So how could we convert 08Mar2007 to YYYYMMDD? The only *small* probleem is the month, because it is a string, we have to convert is to a number:

var asMonths = new Array();

asMonths['Jan'] = 1;
asMonths['Feb'] = 2;
asMonths['Mar'] = 3;

etc.


Now the sort function becomes something like (haven't tested it):

//convert ddMMMYYYY --> yyyymmdd
function datetime(text){var oData = new Date(); return Number(Date.UTC(text.substr(7, 4),asMonths[text.substr(3, 2)],text.substr(0, 2)))}


Hope this helps

An effective workaround,
capture your date format in raw date (ie, long type).

set the cell
<%for(i=0; i<length; i++ ){%>
obj.setCellValue(<%=dateTime%>,0,<%=i%>);
<%}%>

var str = new AW.Formats.String;
var numct = new AW.Formats.Number;

numct.setTextFormat("########");
obj.setCellFormat([numct, str, str, ...]);
obj.setSortColumn(0);
obj.setSortDirection("descending", 0);

This will work in any extreme condition
