Can You help me, please. I need only this to finish my work.

Thank you. If you want, send me an e-mail.

Hi.

I have some data like so :

{
{ total : 300, year : 2001 }, // total for the entire year
{ total : 300, year : 2001, quarter : 1 }, // total for an entire quarter
{ total : 250, year : 2001, quarter : 1, month : 1 }, // total for a specific month
{ total : 275, year : 2001, quarter : 1, month : 2 },
{ total : 300, year : 2001, quarter : 1, month : 3 },
{ total : 300, year : 2001, quarter : 2 },
{ total : 250, year : 2001, quarter : 2, month : 4 },
{ total : 275, year : 2001, quarter : 2, month : 5 },
{ total : 300, year : 2001, quarter : 2, month : 6 },
{ total : 300, year : 2001, quarter : 3 },
{ total : 250, year : 2001, quarter : 3, month : 7 },
{ total : 275, year : 2001, quarter : 3, month : 8 },
{ total : 300, year : 2001, quarter : 3, month : 9 },
{ total : 300, year : 2001, quarter : 4 },
{ total : 250, year : 2001, quarter : 4, month : 10 },
{ total : 275, year : 2001, quarter : 4, month : 11 },
{ total : 300, year : 2001, quarter : 4, month : 12 },
}

As you can see, the aggregations are embedded in the data. Objects missing the quarter and month field are aggregations for the year, and those missing the month fields are aggregations for quarter.

The aggregations don’t follow the inbuilt aggregations of MAX, MIN AVG etc (it is a last-non-empty column, FYI). Is there a way to group this data in an AdvancedDataGrid?

Thanks.

Thanks

if i access the xml directly from the http Service it works fine .

if i do in my dataprovider for ADG as test.lastResult.root.data it works fine .
but if I do the following

inisde the event i do public function showReports(event:ResultEvent):void {

reportList = event.result as XML;
_xlcCatalog = new XMLListCollection(reportList.Product);

}

and then set xlcCatalog as the Data Provider and Group Source .
in Both Cases Grouping works but sum does not work in this case .

Here is what I have done .

//Make a grouping collection
mygroup=new GroupingCollection();
//Set the source to the array collection (this case dataProvider)
mygroup.source = _xlcCatalog;
//Create a new grouping
var group:Grouping = new Grouping();
group.groupingObjectFunction = grpObjFunc;
//Group on Quarter
gf = new GroupingField(”siteNumber”);
//Set the fields to the grouping
group.fields = [gf];
//Finally, Set the group to the grouping property of groupedCollection
mygroup.grouping = group;
//Refresh the group
//Set the dataProvider to the grouping collection
//Call validateNow() to redraw the dg.

adg.dataProvider = mygroup;
mygroup.refresh();
adg.validateNow();
var sr:SummaryRow = new SummaryRow();
//Set the summaryObjectFunction
//This function tells ADG to add a summary row in addition to the existing data
sr.summaryObjectFunction = objFunc;
//Set the summary field. The field on which the summary will be calculated.
var sf:SummaryField = new SummaryField(”SelectedMonthTotals”);
//Summary Function – the function that calculates the summary row display
sf.summaryFunction = func;
//set the summary rows fields property to summaryField
sr.fields = [sf];
//Place the summary row (Last means data First, summary Last!)
sr.summaryPlacement = “last”;
//Group on Quarter
//var gf1:GroupingField = new GroupingField(”siteNumber”);
//set the summary row(s) to groupingField
gf.summaries=[sr];
mygroup.refresh();
adg.validateNow();

Grouping works fine , but Summary row does not show up . It shows up as 0 always .
private function objFunc():SummaryObject
{

var obj:SummaryObject = new SummaryObject();
obj.summary = true;
return obj;
}

private function func(itr:IViewCursor,field:String, str:String=null):Object
{

var sum:Number=0
while(!itr.afterLast)
{

var value:Number = Number(itr.current.siteNumber);
Alert.show(’value’+itr.current.siteNumber);
if(!isNaN(value))
{
sum+= value
}
itr.moveNext()
}
return sum
}

You can use a simple filterFunction on your dataProvider to filter out rows based on column parameters.

Take a look at peter’s posts on filterFunction here – blog.flexexamples.com/tag/filterfunction/

Hope that helps!
Thanks!

I’m facing an issue to skip some rows while rendering the data using advanceddtagrid. I have requirement that I need to avoid some records based on the other column value. ie. If I have a table with the fields Name, Sex.
I should display only names who are male. Can you please send me an example if possible to my mailid.

Thanks,
Siva
