RE: [flexcoders] Re: This is not as easy as it seems ... apparently...
First, to make it completely clear, when working with the data, you must
always use the underlying dataProvider and item and never the DataGrid or
cell itself. This is because itemRenderers are recycled. You can never do
any row level work in a renderer in creationComplete for the same reason,
but must override the set data() function. Google this.
Also, if I am understanding correctly, there are two other ways to do this.
You mentioned labelFunction. That is one way. A label function has access
to the entire row item, and can use the values of any property/cell for the
display logic.
You could also create a value object with a calculated property.
Note that if you update the dataProvider programmatically, you should use
the dataProvider collection API in order to ensure the correct events are
dispatched to update the UI. You can call itemUpdated() if you assign the
value of an item.property directly.

That'll update the value of the cell.
You can't do what you're trying to do. You can't have a column with a
different dataField per row. The dataField for the column is the same for
every row.
Is this data coming from a database, through a view? You really should do
this there. You can set up a view column with an if/then that returns the
column's value you want.

[flexcoders] Re: This is not as easy as it seems ... apparently...
if you just did dataGrid.selectedItem then that would be the selected row. add
[columnname] to get to the column, so:
dataGrid.selectedItem[columnname]
it's not the label, it's the data column name.

Ok... In the parent component to the datagrid I used an initialize event:
public function initDg():void {
if(dgOrdExt.selectedItem[Kind]==LONG)dgOrdExt.Profit.dataField=Profit;
if(dgOrdExt.selectedItem[Kind]==SHORT)dgOrdExt.Profit.dataField=ShProfit;

it does not work. but if I replace the code with dgOrdExt.dataField=Profit;
which just sets the dataField without referencing the other column the code is
all working...
I also tried creationcomplete event and that did not work either.

You can't use selectedItem because there is no selectedItem. You haven't
clicked a row. Try looping through the grid.
In the end, I really don't understand why you don't do this in the
dataCollection, or even in the source data.
for (var i:Number = 0; i mygrid.numChildren; i++) {
if (mygrid.getChildAt(i)[Kind] ==

mygrid.getChildAt(i)[Profit]

now we're getting somewhere! but will this update the value of the col2 or the

Can I use:

That'll update the value of the cell.
You can't do what you're trying to do. You can't have a column with a
different dataField per row. The dataField for the column is the same for
every row.
Is this data coming from a database, through a view? You really should do this
there. You can set up a view column with an if/then that returns the column's
value you want.

I am trying to change the value of col2 DataField to Profit not the value

Can I use:

Ok... In the parent component to the datagrid I used an initialize event:

it does not work. but if I replace the code with
dgOrdExt.dataField=Profit; which just sets the dataField without
referencing the other column the code is all working...
I also tried creationcomplete event and that did not work either.
