  • Use rendered attribute. – Mahmood Apr 19 '17 at 18:23
  • do we need to declare anything in the controller part.. – anjali Apr 19 '17 at 18:26
  • Yes, you need to have boolean property, and use that boolean property in the rendered attribute. The link posted in the other comments should give you a good start. – Mahmood Apr 19 '17 at 18:27

You can use rendered attribute in apex:commandButton like below:

<apex:commandButton value="Confirm" action="{!Confirm}"  rendered="{!ishide}"/>

Modified the class like below by using an extra boolean variable (ishide):

if(case.Person_Role__c==NULL){
 ishide = false;
         ApexPages.addmessage(new ApexPages.message(ApexPages.severity.INFO,'order cannot be created'));
}

make sure you declare the ishide with {get;set;} and in constructor intialize the variable as ishide=true

It is very simple just do the following steps:

  1. create one boolean variable say hidebtn and make the value false

  2. Make it true in the below code: 

    if(case.Person_Role__c==NULL){
    hidebtn = true;
    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.INFO,'order cannot be created'));
}

Put the variable in button rendered condition.

<apex:commandButton value="Confirm" action="{!Confirm}" rendered={!NOT(hidebtn)}/>

It will solve your purpose.
