Using drag/drop to build data grid rows from multiple lists ?

Question

Hi,
I have implemented some simple drag and drop between grids and lists, including images.
What I need to do now is quite a bit more complex:
Create rows in a data grid by dragging and dropping from multiple lists. That is, for a given
row, column 1 receives data from list A and rows in column 2 - 5 receive data from List B
I haven't found any examples that do this and my initial hacks haven't been successful.
If you have any suggestions, they would be most appreciated !!!
Thanks !  

Answer 1

This does the trick...
For my destination grid
protected function dg_dragDropHandler(e:DragEvent):void
// Dynamically add columns to the grid by dragging them from the new column list
                if (e.dragInitiator["id"] == "lNewColumn")
                    e.preventDefault();    // handle this manually
                    var Id:Number;
                    var Name:String;
                    var numCols:int = e.dragInitiator["selectedItems"]["length"] as int;
                    for (var i:int=0; i < numCols; i++)
                        Id = e.dragInitiator["selectedItems"][i]["id"];
                        Name = e.dragInitiator["selectedItems"][i]["Name"];
                        addGridColumn(Id, Name);
private function addGridColumn( Id:Number, Name:String ):void
                var dgc:DataGridColumn;
                var cols:Array = dg.columns;
            // not a duplicate column
                    dgc = new DataGridColumn(Name);
                    dgc.width=150;   
                    dgc.headerWordWrap = true;
                    dgc.itemRenderer=new ClassFactory(MyLovelyItemRenderer);    // unlike mxml, must explicitly cast
                    dgc.width=156;
                    dgc.headerText = Name + "\n Message";
                    dgc.dataField="messageId_" + Id.toString();    // allows split on '_' later to get Id
                    dgc.setStyle("textAlign","center");
                    cols.push(dgc);
                    dg.columns = cols;
