Datagrid sort by number

[jvanv8]

Alright. Looks like we'll just have to figure it out on our own:

//custom sorting functions for the ranking column
// replace "ColumnName" with the name of the column you want to sort
// in this case, my column was located at columnIndex 2, adjust to suit your needs


function sortNumericASC(a, b) {
  return Number(a.ColumnName) > Number(b.ColumnName);
}
function sortNumericDESC(a, b) {
  return Number(a.ColumnName) < Number(b.ColumnName);
}
var headerListener = new Object();
headerListener.headerRelease = function(event){
  trace("column header num. "+event.columnIndex+" was pressed");
  if (event.columnIndex == 2){
    if(sortASC == NULL){
       sortASC = true;
    }else{
       sortASC = !sortASC;
    }
    if(sortASC){
       my_dg.sortItems(sortNumericASC);
    }else{
       my_dg.sortItems(sortNumericDESC);
    }
  }
};
my_dg.addEventListener("headerRelease", headerListener);
