    how to initialize checkbox in flex4

    Venkatesan Balasubramanian

      hi friends,


                   if checkbox selected false means one function will run and checkbox selected true means another function will run, i want to use if and else condition for this.when i try this i am facting error like this how i will rectify,please help



      var chkIncrSlab:Boolean;


      if(chkIncrSlab.selected = false)----> error- Access of possibly undefined property selected through a reference with static type Boolean.

          Firstly, '=' is an assignment operator, use '==' for comparisons.


          Secondly, chkIncrSlab is a Boolean and so does not have a property called selected


          so chkIncrSlab.selected will fail


          I am not 100% sure but, I think you are after something like this?


          <?xml version="1.0" encoding="utf-8"?>
          <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
                                      minWidth="955" minHeight="600">
                         protected function checkBox_changeHandler(event:Event):void
                              if (checkBox.selected)
                         private function sayHello():void
                              label.text = "hello";
                         private function sayGoodbye():void
                              label.text = "good bye";
               <s:VGroup horizontalCenter="0" verticalCenter="0">
                    <s:CheckBox id="checkBox"
                    <s:Label id="label"/>

              did my first post solve your orginal problem?


              the description isn't very clear, best thing to do is post some code that illustrates your issue.


              unforunately I have never worked with datagrids so am unlikely to be able to help
