I receive from the httpservice with a certa开发者_如何学Pythonin frequency a string like this: 1#3#234525234 where row#column#value I want to display into datagrid the above string at real time; at the moment my code displays the whole string, composed by many strings like the one above. How can i solve the problem? Thanks in advance
I have the following code

First of all, the loop seems to be wrong, you iterate over a string source
, not an array.
Secondly, your grid should bind to some properties of objects stored in a dataProvider
(Array, ArrayCollection, etc.). So the data provider shouldn't be a string, as in your code.
Thridly, dataField
is the name of the field of the object stored in the dataProvider
, which value should be displayed in the grid cell.
Basicly, you need to parse your incoming string, store each row in an object and store all these objects in a collection.
So, the code should be something like:
[Bindable]
private var dataList:ArrayCollection;
public function cycle(source:String):void
{
var ac:ArrayCollection = new ArrayCollection();
for(var i:int = 0; i < data.length; i += 3) {
var dataObj:Object = {row: data[i], column: data[i+1], value: data[i+2]};
ac.addItem(dataObj);
}
dataList = ac;
}
<mx:AdvancedDataGrid dataProvider="{dataList}" liveScrolling="true" id="dg"
x="10" y="117" width="621">
<mx:columns>
<mx:AdvancedDataGridColumn dataField="row"
headerText="Riga"/>
<mx:AdvancedDataGridColumn dataField="column"
headerText="Colonna"/>
<mx:AdvancedDataGridColumn dataField="value"
headerText="Valore"/>
</mx:columns>
</mx:AdvancedDataGrid>
