Everyone:
I have used sortCompareFunction attribute of gridcolumn to resolve date sort
issue in my application.
Below is the part of my code
.....
<mx:DataGridColumn headerText="Date" columnName="joinDate" width="100"
sortCompareFunction="sortGrid" labelFunction="formatDate" />
.....
function sortGrid(a, b, index) {
if (a == b)
return 0;
else if (a < b)
return -1;
else
return 1;
}
function formatDate(rowData):String {
var dFormat = new mx.formatters.DateFormatter();
return (dFormat.format(rowData.feedbackCreationDate));
}
....
1. But now I'm facing a performance issue. My application is populating 1000
records in the grid and when I click on the header to sort grid on date order
then it hangs the application and throw script error "A script in this movie is
causing Macromedia Flash Player 8 to run slowly. If continues to run, your
computer may become unresponsive. Do you want to abort the script?"
Same script works fine if I populate with less number of records, say 100, in
grid but then this takes more then 10 secs to sort data. Do we have any
solution to this issue?
Also, if I remove labelFunction then script works fine for 1000 records but
takes long time to order all data.
2. Is it possible to remove ordering from the grid and show default order list?
Click one will sort data in ascending order, Click two will sort data in
descending order and Click three will show the default order or remove ordering
from the grid.
Regards,
Nischal Pathania

sortCompareFunction is meant for you controlling the sort regardless of whether
you had a cell renderer. You just need the DataGridColumn. In your case since
the data is already formatted using the labelFunction you may want the
sortCompareFunction to work on the unformatted value.

Ya I have tried that but from I understand that only work when the date is from
cell renderer. Mine is coming from a java object and is using label to format
it.

If it's not working by default you may want to look into the
sortCompareFunction on DataGridColumn.

Is there a way to sort a date field in a data grid that is using a
labelfunction to get the date value. I have read that it can be done
when using a cell renderer, but I do not want to change the code. Can
this be done? Thanks.
