Disabling Picklist field by selecting radio button.

Hi,

I have Created a Radio Button with options 'YES' & 'NO' .   and created a Multi select picklist field below.

Now my requirement is
1. In Radio button, If YES is selected then picklist values on below has to be enable and give choice to select from the  multi picklist
2. In radio Button, If NO is selected then Picklist values has to be disable. 

Can any one help me to do this functionality. If so it would be helpfull to me.

Thanks,
Suresh Goud

Hi,

 

Try this code,

 

<apex:page controller="sampleCon">

<script type="text/javascript">
     
    function getActive(selectedValue) 
    {  
    if( selectedValue == 'YES')
    {
    var ele=document.getElementById('{!$Component.form1.dropdown}');
      ele.disabled =false;
    }else if(selectedValue == 'NO')
    {
         var ele=document.getElementById('{!$Component.form1.dropdown}');
      ele.disabled =true;
    }
      
            
    } 
    </script>
    <apex:form id="form1">
        <apex:selectRadio value="{!selectedValue}" layout="pageDirection" onchange="getActive(this.value);">
            <apex:selectOption itemValue="YES" itemLabel="YES"/>
            <apex:selectOption itemValue="NO" itemLabel="No"/>
            </apex:selectRadio><p/>
            
            <apex:selectList id="dropdown" size="1">
               <apex:selectOption itemValue="YES" itemLabel="YES"/>
            <apex:selectOption itemValue="NO" itemLabel="No"/>
            </apex:selectList>
            
  </apex:form>
</apex:page>

 

public class sampleCon {
    public String selectedValue{get;set;}

If the Yes/No option is a Picklist field type, you could use the built-in dependent picklists functionality. However, I'm not sure it would work if you're using radio buttons rather than the inputField control (which would appear as a dropdown list rather than a radio button)

 

If it's an option to make the Yes/No field a dropdown list rather than a radio button, then dependent picklist functionality should work without any custom coding.

Hi,

 

Try this code,

 

<apex:page controller="sampleCon">

<script type="text/javascript">
     
    function getActive(selectedValue) 
    {  
    if( selectedValue == 'YES')
    {
    var ele=document.getElementById('{!$Component.form1.dropdown}');
      ele.disabled =false;
    }else if(selectedValue == 'NO')
    {
         var ele=document.getElementById('{!$Component.form1.dropdown}');
      ele.disabled =true;
    }
      
            
    } 
    </script>
    <apex:form id="form1">
        <apex:selectRadio value="{!selectedValue}" layout="pageDirection" onchange="getActive(this.value);">
            <apex:selectOption itemValue="YES" itemLabel="YES"/>
            <apex:selectOption itemValue="NO" itemLabel="No"/>
            </apex:selectRadio><p/>
            
            <apex:selectList id="dropdown" size="1">
               <apex:selectOption itemValue="YES" itemLabel="YES"/>
            <apex:selectOption itemValue="NO" itemLabel="No"/>
            </apex:selectList>
            
  </apex:form>
</apex:page>

 

public class sampleCon {
    public String selectedValue{get;set;}

The last code also doesn't work. The fields are not getting disabled.
