Building Spark DataGrid dynamically
Hi,
I am building a screen with one Static DataGrid and one Dynamic (data comes
through SOAP
and I do not know the number of columns or their names in advance).
I also get a list of column names in order from another SOAP call.
That Dynamic DataGrid works (converting data from Vector of Objects to
ArrayList of Columns).
I still have a few problems:
1) I need to implement "Clear" of that Dynamic table.
No matter what I tried:
arrayColl=null;
arrayColl.removeAll();
arrayColl = new ArrayCollection();
myDG.dataProvider=null;
myDG.dataProvider=new ArrayCollection();
I am getting NULL reference exception coming from some system code: if
(cell.visible)... where cell is null.
How can I clear that dynamic DG ?
full exception stack:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
at spark.components.gridClasses::GridLayout/updateTypicalCellSizes()
at spark.components.gridClasses::GridLayout/measure()
at spark.components.supportClasses::GroupBase/measure()
at mx.core::UIComponent/measureSizes()
at mx.core::UIComponent/validateSize()
at spark.components::Group/validateSize()
at mx.managers::LayoutManager/validateSize()
at mx.managers::LayoutManager/doPhasedInstantiation()
at mx.managers::LayoutManager/doPhasedInstantiationCallback()
2) It seems that by default that Dynamic DG puts columns in alphabetical
order, which is of course not what I need.
Any way to disable that or fix somehow?
3) I need to show 2 DGs on the screen, and the second of them is Dynamic,
and allow user to resize them vertically to be able to see more in static
or dynamic DG.
I put them in VDividedBox (and set height of both DG and container to 100%).
It split the screen vertically 50:50, but still there is no draggable in
between,
so can't resize.
Any help is very appreciated.
TIA,
Oleg.

It is Flex 4.5.1 (client requirement :-( )
I will send full trace with numbers tomorrow.
No, I haven't tried Flex 4.9-4.10 yet.
Thanks,
Oleg.

HI,
What version of the SDK are you using? Does teh same happen using 4.9.1 or 4.10 (has been a large number of RTE fixes in 4.10). Can you post a full stack trace with line numbers?

Prabhu,
That was very useful.
Also how can I do Validation on some of these dynamic fields,
like user should not be able to enter Alphanumeric if that is an Integer
field.
Please advice.
TIA,
Oleg

Below code render datagrid columns in original order,
var colArr:ArrayList = new ArrayList();
var colNames:Array=//Assign list of Datagrid column names
var len:int = colNames.length;
for(var i:int=0;i<len;i++)
{
var gc:GridColumn = new GridColumn(colNames [i]);
colArr.addItem(gc);
}
dg.columns = colArr; //dg is mxml datagrid id
dg.dataProvider = dgAC;//Assign Datagrid arrayCollection data
Thanks & Regards

Yes, it fixed that exception: arrCol.source=new Array( { "" : ""} );
Any suggestions how to resolve items 2 & 3 (show columns in original order
and implement VDividerBox when second datagrid populated dynamically) ?

Thank you,

RE: Building Spark DataGrid dynamically
Posted by Maurice Amsellem <ma...@systar.com>.
Here is a possible workaround:
Instead of clearing the DG (which anyway wouldn't look very nice), what about setting it to one single empty column ( that is : GridColumn headerText= " " and dataField="_nonExistingField_" ) .
That way, it still looks like a datagrid, although empty and it probably won't break.
What do you think?

Objet : Re: Building Spark DataGrid dynamically
No, it is Clients code, I can't post it. I am getting data dynamically via SOAP, convert it to Vector of Objects, then to ArrayCollection, and pass it to Spark DG dataprovider. Datagrid is declared in MXML without any columns.
That's it. But as I said, can't clear that AC. Any idea how to avoid that Null Reference?

Re: Building Spark DataGrid dynamically
Posted by Oleg Konovalov <ol...@gmail.com>.
No, it is Clients code, I can't post it. I am getting data dynamically via
SOAP, convert it to Vector of Objects, then to ArrayCollection, and pass it
to Spark DG dataprovider. Datagrid is declared in MXML without any columns.
That's it. But as I said, can't clear that AC. Any idea how to avoid that
Null Reference?

Could you post a code sample? I've seen many strange things, but you must
be doing something really funny there.
