Hello,
I am trying to populate a datagrid in ActionScript, but am
unable to do. However, if I do it in mxml, I am able to see the
data.
Here is my relevant mxml code.
public var players:ArrayCollection;
private function fillPlayers(event: ArrayCollection):void {
players = event;
mainTxt.text = "Getting filled later";
}
private function displayRackInfo():void {
playMe.getPlayersAsList(); // This fills the players
collection.
var rackInfoGrid:DataGrid = new DataGrid();
rackInfoGrid.dataProvider = players;
var firstName:DataGridColumn = new
DataGridColumn("firstName");
var lastName:DataGridColumn = new
DataGridColumn("lastName");
var rackColumns:Array = new Array(firstName, lastName);
rackInfoGrid.columns = rackColumns;
if (players == null) {
mainTxt.text = "NULL"; // Print NULL in TextArea box
}
if (players != null) {
mainTxt.text = "NOT NULL"; // Print NOT NULL in TextArea box
}
rackInfoPanel.addChild(rackInfoGrid);
PopUpManager.addPopUp(rackInfoPanel, this, true);
}
]]>
</mx:Script>
<mx:RemoteObject id="playMe"
destination="PlayerService">
<mx:method name="getPlayerList"
result="fillPlayers(event.result as ArrayCollection)"/>
</mx:RemoteObject>
PlayerService code is below :
public List getPlayersAsList() {
System.out.println("List method called");
List players = new ArrayList();
Player michael = new Player("Michael","Jordan");
Player scottie = new Player("Scottie","Pippen");
players.add(michael);
players.add(scottie);
return players;
}
The datagrid shows headers, but no data. Also my print
messages show that the remote service is being called. Also in my
action script method, once I get the 'NULL' message and another
time, I get the 'NOT NULL' message.
If I take the datagrid out of ActionScript and populate it in
mxml, it works just fine. I see the entire data.
<mx:DataGrid dataProvider="{players}" height="100"
width="100%">
<mx:columns>
<mx:DataGridColumn dataField="firstName"
headerText="FirstName"/>
<mx:DataGridColumn dataField="lastName"
headerText="LastName"/>
</mx:columns>
</mx:DataGrid>
The reason I am trying to do in ActionScript is because i
want the datagrid to open only when a user event happens. User
clicks a button, and then the datagrid pops up. If I do it in mxml,
I am unable to get that behaviour. Datagrid is visible right from
the start of the application.
Please help.
Thanks.
