Or just use List.

Subject: Re: [flexcoders] Re: ArrayCollection of String as single-column
DataGrid provider

 

You have a couple of choices... you could translate the strings to
objects with a single property (loop over them), then feed that array to
a standard DataGrid.  Or, if you plan to be doing a lot of this, you
could create a custom component that does the job internally.  It is a
pretty trivial exercise to build a custom data grid that does what you
want.  Try the code below to get you started.  NOTE: code created in
this editor and may not even compile... but, it'll get you close :)

This code does not create your column for you etc.  Instead it counts on
you to create it in your MXML where you create your StringGrid.  Note
however, that you could do that in this class as well... maybe have a
public property for the headerText of the single column, then create the
column internally giving it the headerText from the property and the
dataField of "label"

   public class StringGrid extends DataGrid
   {   
      public override function set dataProvider(value:Object):void
      {
          var myDP:ArrayCollection = new ArrayCollection();
          if(value is Array)
          {
              var strArray:Array = Array(value);
              for each(var str:String in strArray)
              {
                  var obj:Object = new Object();
                  //need to use label in  your datagrid column
                  obj.label = str;
                  myDP.add(obj);
              }
              super.dataProvider = myDP
          }
          else
          {
             super.dataProvider = value;
          }
      }
   }

Ok, how do I display and edit ArrayCollection that contains only
String types in it if I can't use DG?

        You cannot use simple types (String, Number) in a DG.  You have
to use
        objects like:
         
         
         
        <mx:Object label="String1" />
