Hii Tracy,
Here is my repeater(am using 3 repeaters, to have three columns to prevent
having a scrollbar).
Suggest me if there is any better way to do this, although it's not the
issue at the moment.
I have highlighted the problematic code in handler method below.
Code for repeater:
<mx:HBox id="hb" height="100%" width="100%">
<mx:VBox id="vb1" height="100%" width="200">
<mx:Repeater id="r1" dataProvider="{myData}" startingIndex="1"
count="20"
repeat="validateChecks(event)">
<mx:CheckBox id="chkFirstColumn"
label="{r1.currentItem.keyword_value_id}"
data="{r1.currentItem}"/>
</mx:Repeater>
</mx:VBox>
<mx:VBox id="vb2" height="100%" width="200">
<mx:Repeater id="r2" dataProvider="{myData}" startingIndex="21"
count="20"
repeat="validateChecks(event)">
<mx:CheckBox id="chkSecondColumn"
label="{r2.currentItem.keyword_value_id}" data="{r1.currentItem}"/>
</mx:Repeater>
</mx:VBox>
<mx:VBox id="vb3" height="100%" width="200">
<mx:Repeater id="r3" dataProvider="{myData}" startingIndex="41"
count="20"
repeat="validateChecks(event)">
<mx:CheckBox id="chkThirdColumn"
label="{r3.currentItem.keyword_value_id}" data="{r1.currentItem}"/>
</mx:Repeater>
</mx:VBox>
</mx:HBox>
Code for Handler:
private function validateChecks(e:Event):void{
if(e.currentTarget.id == "r1" && existingData.length() > 0){
for(var j:uint = 0; j < existingData.length(); j++){
if(e.currentTarget.currentItem.keyword_value_key ==
existingData[j].keyword_value_key){
e.currentTarget.currentItem.selected = true;
//Problem is here. It's not
working.I want to refer the checkbox inside repeater here.
}
}
}
}
