hey all......
I am new to flex.
i m working on a flex project in which i am using
advanced data grid control and trying to customize its properties.
In my project i have created grouping at runtime.For this i have made
a function and it is working fine.
Now i need to print no of children in the label of groupinglabel like
this
FolkSongs(8)
Sad(4) etc
could you help me for this..........One more thing i am using flat
data for my application so there is no tag like children by which i
can access children. I am telling you this because i was using
hierarchical data for my application before and by using children
tag , i was able to print its children through itemrenderer.but now i
have changed heirarchical data with the flat data.
For this i wrote a function. I think some changes to this function
will work for me .
function for creating run time grouping
public var myGColl:GroupingCollection = new GroupingCollection();
private var myGrp:Grouping = new Grouping();
public function initDG(strHeaderName:String):void {
myGColl.source = dpFlat;
myGrp.fields = [new GroupingField(strHeaderName)];
myADG.dataProvider=myGColl;
myGColl.refresh();
}
Function for printing no of children when i was using hierarchical
data, I used this function as a labelfunction it is returning label
text to item renderer.
public function
groupLabelFunction(item:Object,column:AdvancedDataGridColumn):String{
if (item && item.children)
{
;
return item[column.dataField] + " (" + item.children.length + ")";
}
else
{
return item[column.dataField];
}
}
flatdata file
private var dpFlat:ArrayCollection = new ArrayCollection([
