RE: [flexcoders] Custom Datagrid Sorting

[Steve Cox]

Thanks for the reply Abdul,   I’ve been unable to find an answer to my question in the archives though. I can get the sorting working perfectly if I explicitly set the object I want to sort on (as is done in all the examples I could find), however the name of the column to be sorted needs to passed to the class ideally.   In Mike Chambers version for example he uses: return toggle * compareDates(item1.date,item2.date);   Now that’s fine when you know that you want to sort on .date but what happens when the dataprovider has different columns to sort on?   In my app I have maybe 50 datagrids most of which have a date of some sort. Whether it be startDate, endDate, bookingDate etc.   Ideally I want to call return toggle * compareDates(item1[field],item2[field]);  where field is a private variable inside the class telling the sort function the name of the column to sort on. However due to the way the function is passed I can’t think of any way to let that function access a variable.   Cheers,   Steve     -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Abdul Qabiz Sent: 25 August 2005 18:14 To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Custom Datagrid Sorting   Hi Steve,   Similar question has been replied in past, I have replied once myself.

I’ve got this all working, however I’m trying to package it up as a class so I can reuse it 100 times through the various datagrids I’ve got. My problem is I’m calling:   dg.dataProvider.sortItems(dateFieldCompare, ((sortOrder == 1)? 0: Array.DESCENDING));   Where dg is my datagrid (passed through via the class constructor). The issue I’m having is that I cannot access any variables from the dateFieldCompare function. My constructor header is as follows:   public function DateSortUtil(myDg:mx.controls.DataGrid,columnIndex:Number,field:String) {   Ideally I want field to be accessible to the dateFieldCompare function so I know what field to compare. The following is the header from dateFieldCompare:   private function dateFieldCompare(item1:Object, item2:Object, bit:Number):Number   To get it working at the moment I’m having to compare item1.date and item2.date . However ‘date’ won’t always be the name of the fields I want to compare, and item1[field] isn’t going to work.   Any ideas?   Cheers, Steve -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Computer software testing Macromedia flex Development Software developer YAHOO!
