Hi Experts,

I am trying to do multiple column sorting on adg. when i click in the header , the data getting sorted in reverse way. here is my code snippet.

private function sortSub(itemA:Object, itemB:Object):int
                  {
                        var messageA:MessagerVo = itemA as MessagerVo ;
                        var messageB:MessagerVo = itemB as MessagerVo ;
                        if(messageA.priority == messageB.priority)
                        {
                              var unReadA:int;
                              var unReadB:int;
                              if(messageA.unRead)
                              {
                                    unReadA = 1;
                              }else{
                                    unReadA = 0;
                              }
                              if(messageB.unRead)
                              {
                                    unReadB = 1;// unread 1, read 0
                              }else{
                                    unReadB = 0;// read
                              }

                              if(unReadA == unReadB)
                              {
                                    return ObjectUtil.dateCompare(messageA.createDate,messageB.createDate);
                              }

                              return ObjectUtil.numericCompare(unReadA,unReadB);
                        }
                        return       ObjectUtil.numericCompare(int(messageA.priority),int(messageB.priority));
                  }

yeah I used it. I am able to do multiple sorting but what my problem is I could not display the data in correct order i.e for example if i put all messages with value 0 in objA and messages with value 1 in objB of one column..after clicking on header sorting should be done and dispalyed in correct order(i.e.if in objA the messages are in the order say 1 2 3 4 should be displayed in the same order 1 2 3 4 even after sorting)

@dgofman:

If u dont mind can u be elaborate ? thx

dgofman

I can but i need to get from you example of your object array and expecting result after applying a sorting

message object contains a,b,c,d column fields and x,y,z values. in column a messages need to be sorted by x value.(x will have 0 and 1 ). when we click on header of column a, the other columns should also be sorted( column b and c should be sorted by their boolean values) and column d will be sorted by date values. thanks

column d should be sorted according to the x values. i.e. dates belong to the x=0 as one object and other dates in other object.

dgofman

I am still confused lets believe we have such data tell me how do you want to sort it?

df1 df2
1 a
5 e
2 b
4 d
3 c
