flex4 - CheckBox and RadioButton validation - actionscript-3

Question

In my application i have both radio buttons and check boxes. Here I want to validate both CheckBox and RadioButton when I move to the next contol.
Edit:
My coding is here
<fx:Declarations>
<s:RadioButtonGroup id="genderOption"/>
<mx:StringValidator
id="radioButtonValidator"
source="{genderOption}"
property="selectedValue"
trigger="{groupLevel}"
listener="{groupLevel}"
required="true"
requiredFieldError="field is required"/>
<mx:StringValidator
id="checkBoxValidation"
source="qualificationGroup"
required="true"
property="selectedValue"
listener="{qualificationGroup}"
requiredFieldError="field is required"/>
</fx:Declarations>
<s:layout>
<s:HorizontalLayout/>
</s:layout>
<mx:HDividedBox width="100%" height="100%">
<s:Panel id="mainPanel" title="Employee Details" height="100%" width="50%">
<s:Form id="mainForm" height="100%" width="100%" left="10%" right="10%" top="10%">
<s:FormItem id="genderLabel" label="Gender" showErrorSkin="true" showErrorTip="false">
<s:HGroup id="groupLevel">
<s:RadioButton group="{genderOption}" label="Male" id="male" selected="false"/>
<s:RadioButton group="{genderOption}" label="Female" id="female" selected="false"/>
</s:HGroup>
</s:FormItem>
<s:FormItem id="quaLabel" label="Qualification" showErrorSkin="true" showErrorTip="false">
<s:HGroup id="qualificationGroup">
<s:CheckBox id="bsc" label="B.Sc"/>
<s:CheckBox id="be" label="BE"/>
<s:CheckBox id="mca" label="MCA"/>
<s:CheckBox id="mba" label="MBA"/>
<s:CheckBox id="others" label="Others"/>
</s:HGroup>
</s:FormItem>
</s:Form>
</s:Panel>
</mx:HDividedBox>
And I am the new one for flex. If i am using change or click event, it will display the error message via alert box. But i don't want alert box. Is any other way to display the error message is there?

Answer 1

When you move to the next control add and event listener to call a function to preform the validation checks.
Without more information i cant say which event listener will be applicable, but it will most likely be a click event.
<Script>
<![CDATA[
protected function validate_HDivide(event:MouseEvent):void
{
if(mycheckboxes.validate())
{
//do things
}
else
{
//display error
}
}
<s:HDividedBox id="mycheckboxes" change="validate_HDivide(event)"/>
<s:Button label="submit" click="validate_HDivide(event)"/>
then within your HDividedBox you can preform your validation
Thats how i would do it, hope this help.
