How about if the checkbox is on another page or component & i want to enable a button on separate component on the selection of checkbox.Also I want to know if there is any count property associated with the checkbox.

In the project I’m using, I use a seperate MXML file and put it into the main project, and the way FLEX refers to it is by using some command that I haven’t been able to find any information online. I was wondering if you knew how to have a checkbox inside this seperate MXML file and have it make the button appear in the main MXML file. I’m sorry if it’s not too clear.

Do either of these work for you?

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">

    <mx:Panel title="Any" width="320">
        <mx:CheckBox id="check1a" label="Check 1.A" />
        <mx:CheckBox id="check2a" label="Check 2.A" />
        <mx:CheckBox id="check3a" label="Check 3.A" />
        <mx:ControlBar>
            <mx:Button label="Button A" enabled="{check1a.selected || check2a.selected || check3a.selected}" />
        </mx:ControlBar>
    </mx:Panel>

    <mx:Panel title="All" width="320">
        <mx:CheckBox id="check1b" label="Check 1.B" />
        <mx:CheckBox id="check2b" label="Check 2.B" />
        <mx:CheckBox id="check3b" label="Check 3.B" />
        <mx:ControlBar>
            <mx:Button label="Button B" enabled="{check1b.selected &amp;&amp; check2b.selected &amp;&amp; check3b.selected}" />
        </mx:ControlBar>
    </mx:Panel>

</mx:Application>

Or, using ActionScript instead of MXML:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">

    <mx:Script>
        <![CDATA[
            private function chkA():void {
                btnA.enabled = (check1a.selected || check2a.selected || check3a.selected);
            }
            private function chkB():void {
                btnB.enabled = (check1b.selected && check2b.selected && check3b.selected);
            }
        ]]>
    </mx:Script>

    <mx:Panel title="Any" width="320">
        <mx:CheckBox id="check1a" label="Check 1.A" change="chkA();" />
        <mx:CheckBox id="check2a" label="Check 2.A" change="chkA();" />
        <mx:CheckBox id="check3a" label="Check 3.A" change="chkA();" />
        <mx:ControlBar>
            <mx:Button id="btnA" label="Button A" creationComplete="chkA();" />
        </mx:ControlBar>
    </mx:Panel>

    <mx:Panel title="All" width="320">
        <mx:CheckBox id="check1b" label="Check 1.B" change="chkB();" />
        <mx:CheckBox id="check2b" label="Check 2.B" change="chkB();" />
        <mx:CheckBox id="check3b" label="Check 3.B" change="chkB();" />
        <mx:ControlBar>
            <mx:Button id="btnB" label="Button B" creationComplete="chkB();" />
        </mx:ControlBar>
    </mx:Panel>

</mx:Application>

I’m using the same button in different states, and I’m just using the function to make the button go to the next state, depending on which state its already in. However, lets say in state 1 i want the button enabled, but in state 2 I want it to be disabled, and only enabled if the checkbox is selected, i used the

However, when I do so, the button doesn’t enable itself as soon as the checkbox is selected, but if i select the checkbox, go back to state 1, and then return to state 2, then the button is enabled.

Any insight on how to fix this?
