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.

[flexcoders] Re: This is not as easy as it seems ... apparently...
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...
now we're getting somewhere! but will this update the value of the col2 or the
value of col2 DataField?
I am trying to change the value of col2 DataField to "Profit" not the value of
col2 itself.
Can I use:
dgOrdExt.getChildAt(i)["Profit"].dataField = "Profit"

[flexcoders] Re: This is not as easy as it seems ... apparently...
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"] ==
"LONG") {
mygrid.getChildAt(i)["Profit"]
= "Profit";
}
else { mygrid.getChildAt(i)["Profit"] = "ShProfit"; }

[flexcoders] Re: This is not as easy as it seems ... apparently...
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.

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. --- In flexcoders@yahoogroups.com, "Craig" wrote: > > yes the datagrid is bound to an array collection. > I don't want to select any item, I want to change the value of a column's > DataField to a one of two values based on the value of another column's > output. > > I don't want to have to 'selecteditem' but I can try that code below are you > suggesting that I use it in the labelfunction of the datagrid column that I > am trying to change? > > > --- In flexcoders@yahoogroups.com, "postwick" wrote: > > > > Is the datagrid bound to a collection? if so, change the value in the > > collection. > > > > or try... > > > > yourDataGrid.selectedItem["dataColumn1"] = > > yourDataGrid.selectedItem["dataColumn2"] > > > > --- In flexcoders@yahoogroups.com, "Craig" wrote: > > > > > > I am trying to set the value of a column based on the value of another > > > column.

Is the datagrid bound to a collection? if so, change the value in the collection. or try... yourDataGrid.selectedItem["dataColumn1"] = yourDataGrid.selectedItem["dataColumn2"] --- In flexcoders@yahoogroups.com, "Craig" wrote: > > I am trying to set the value of a column based on the value of another > column.

yes the datagrid is bound to an array collection. I don't want to select any item, I want to change the value of a column's DataField to a one of two values based on the value of another column's output.

so if it's doing it row by row, then it would need to be a labelfunction event right? where would you suggest the code go? there needs to be an if (datagrid.seleteditem["Kind]=="LONG")datagrid.selecteditem[Profit]="Profit"; then another line that stipulate the other option: if (datagrid.selecteditem[Kind]=="Short")datagrid.selecteditem[Profit]="ShProfit"; --- In flexcoders@yahoogroups.com, "postwick" wrote: > > 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. > > --- In flexcoders@yahoogroups.com, "Craig" wrote: > > > > yes the datagrid is bound to an array collection. > > I don't want to select any item, I want to change the value of a column's > > DataField to a one of two values based on the value of another column's > > output. > > > > I don't want to have to 'selecteditem' but I can try that code below are > > you suggesting that I use it in the labelfunction of the datagrid column > > that I am trying to change? > > > > > > --- In flexcoders@yahoogroups.com, "postwick" wrote: > > > > > > Is the datagrid bound to a collection? if so, change the value in the > > > collection. > > > > > > or try... > > > > > > yourDataGrid.selectedItem["dataColumn1"] = > > > yourDataGrid.selectedItem["dataColumn2"] > > > > > > --- In flexcoders@yahoogroups.com, "Craig" wrote: > > > > > > > > I am trying to set the value of a column based on the value of another > > > > column.

Is there a particular row you want to update? If a row is selected, you would use...

You access the value in a column of a datagrid like this... yourDataGrid.selectedItem["dataColumnNameOfColumn"] --- In flexcoders@yahoogroups.com, "Craig" wrote: > > I GIVE UP!!

I GIVE UP!! I have tried everything!!.. I have a dataGrid that binds to an ArrayCollection. I need to change the value of one columen (Profit) based on the value of another column (Kind) ie.. the results (either 'LONG' or SHORT'). Here is where I'm at. I've tried putting code into customer DataGridColumns and labelFunctions and ItemRenderers... but can not do it. What seem to be working most are events in the DataGrid Component, better than others, but comparing values in a DataGrid is obviously impossible. Somehow I need the code to access ArrayCollection getItemat() but I can't do it! Please help! http://www.adobe.com/2006/mxml"; initialize="initTA()">
