Ah nice idea, but I must be thick because I just can't get it to go.

I have the array/collection as:

public var file_prioritylist:Array = [1, 2, 3, 4 ];
[Bindable]
public var file_priority:ArrayCollection = new 
ArrayCollection(file_prioritylist);


I have the labelFunction as:

// priority labelFunction
public function priorityLabelFunc(item:Object):String {
return item.priority + _teststring;
 }

the datagrid is being populated by a remote dataprovider arraycollection which 
contains the priority etc:

Bindable]
public var files_datagrid:ArrayCollection;

mx:DataGrid id=fileDatagrid x=0 y=0 width=715 height=130 
dataProvider={files_datagrid} change=putVideo() selectedIndex=0

and the column in question is laid out as:

mx:DataGridColumn id=prioritycolumn headerText=Priority width=90 
dataField=priority labelFunction=priorityLabelFunc
mx:itemRenderer
mx:Component
mx:ComboBox 
dataProvider={parentDocument.file_priority} 
mx:idfileprioritycb/mx:id
/mx:ComboBox
/mx:Component
/mx:itemRenderer
/mx:DataGridColumn

Which leads to a error of:

Argument count mismatch on Approval_System/priorityLabelFunc(). Expected 1, got 
2.

if I edit it to move the labelfunction to the combobox and parentDocument it to 
get to the function I get:

Cannot access a property or method of a null object reference.

I am sure I am just missing something simple so any insight appreciated

Hi Tia,

I think this accomplishes what you're trying to do...

mx:DataGrid id=fileDatagrid x=0 y=0 width=715 height=130
dataProvider={files_datagrid} selectedIndex=0
   mx:columns
   mx:Array
   mx:DataGridColumn id=prioritycolumn
dataField=file_priority headerText=Priority width=90
   mx:itemRenderer
   mx:Component
   mx:ComboBox
selectedIndex={data.file_priority- 1} dataProvider={
parentDocument.file_prioritylist}
change=data.file_priority =
this.selectedItem.data 
   mx:idfileprioritycb/mx:id
   /mx:ComboBox
   /mx:Component
   /mx:itemRenderer
   /mx:DataGridColumn
   /mx:Array
   /mx:columns
   /mx:DataGrid

   mx:Script
   ![CDATA[
   import mx.collections.ArrayCollection;

   public var file_prioritylist:Array = [{label: 1, data:1},
 {label: 2, data:2},
 {label: 3, data:3},
 {label: 4, data:4}];

   [Bindable]
   public var file_priority:ArrayCollection = new
ArrayCollection(file_prioritylist);


   [Bindable]
   public var files_datagrid:ArrayCollection = new ArrayCollection;

   private function init():void
   {
   var tmpArray:Array = new Array();
   tmpArray.push({file_priority: 1});
   tmpArray.push({file_priority: 2});
   tmpArray.push({file_priority: 3});
   tmpArray.push({file_priority: 4});
   files_datagrid.source = tmpArray;
   }

[flexcoders] sort compare more than 2 items?

2007-01-25 Thread Impudent1 
I have an array that populates a datagrid combobox item renderer of:

public var file_prioritylist:Array = [High, Medium, Normal, Low ];
[Bindable]
public var file_priority:ArrayCollection = new
ArrayCollection(file_prioritylist);

to avoid them sorting alphabetically I setup a sortCompareFunction for 
that column to use this function:

private function prioritySort(item1:Object, item2:Object):int
{
if (item1.priority == High )
{
return 1;
}
else if( item1.priority == Low )
{
return -1;
}
else
{
return 0;
}
}

which will get it to sort high or low, but how do I get it to sort the 
normal and medium appropriately??? I would also like to be able to group 
the datagrid list by values.

http://stackoverflowexception.blogspot.com/2007/01/minor-update-of-grid-component.html

has an example of what would pretty well cover it but I cannot get it to 
work with the swc file. I would also like to be able to learn from the 
code than just use it.

Why not use numeric values for your priority... you wouldn't have to use a
special sort function, but instead just use a labelFunction for display in
the datagrid to acheive your high/medium/normal/low counts.
