How to make the check box as required field using apex code?I tried with Required="true".But it is not working.The user should navigate to the next page only when the check box is checked.
Can anyone provide the solution?
I'll workup an example that shows how to handle this in a bit but one question I have for you is how you intend to insure that this affirmation page is always presented and presented once and only once since it appears that you are not persisting the results (e.g. in a custom object).?
Here is an example of how I would handle this:
<apex:page controller="spptc"> <br/><b>Terms and Conditions</b><br/><br/> <hr/> <apex:form id="theForm"> <apex:pageMessages /> <center><u><b><font color="blue">Print Terms and Conditions</font></b></u></center><br/><br/> <center><textarea rows="1" cols="100" readOnly="true">PLEASE READ CAREFULLY. These Terms and Conditions ("Terms") govern your access...</textarea></center><br/> <center><apex:inputCheckbox id="box1" value="{!accepted}" required="true"/><b>I accept these terms and conditions</b></center><br/> <center> <apex:commandButton action="{!acceptTerms}" value="Submit" rerender="theForm"/> <input type="button" value="Cancel" class="btnClass"/> </center> </apex:form> </apex:page>public class spptc { public boolean accepted { get; set; } public PageReference acceptTerms() { if (accepted) { return new PageReference('/home/home.jsp'); } else { ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.FATAL, 'You must accept the Terms and Conditions to continue')); return null; } } public PageReference cancel() { // Not sure what you want to do here???return null; } }
