Hi Saroja,

Follow these steps:
1. Go to Setup
2. Quick find "Profiles"
3. Go to your user's profile
4. Add your Visualforce page in the related list "Enabled Visualforce Page Access" of that profile. See the screenshot for reference:

Hi Gaurish,

Thank for the replay.

Already the vf page add to the user profile and the user profile is System Administrator.

Oh your ID parameter is wrong in the URL or somewhere in the controller. You need to put the correct ID.

Here is my page and controllor.

Can you please tell me in which ID parameter is wrong?

Vf page

<apex:page standardController="Contact" extensions="RelatedController1">
<apex:form >
    <apex:pageBlock mode="Main detils">
        <apex:pageblockButtons >
            <apex:commandButton value="save" action="{!save}"/>
            <apex:commandButton value="Cancel" action="{!cancel}"/>
         </apex:pageblockButtons>
        <apex:pageBlockSection title="Contact details">
            <apex:inputField value="{!contact.LastName}"/>
            <apex:inputField value="{!contact.FirstName}"/>
        </apex:pageBlockSection>
       <apex:pageblockSection title="Contact" id="scholid">
           <apex:inputField value="{!contact.School__r.Id}">
            <apex:actionSupport event="onchange" action="{!SchoolPopulated}" rerender="scholid, msgs" status="stat"/> 
          </apex:inputField>
          <apex:outputField value="{!contact.School__r.First_Name__c}"/>   
           <apex:outputField value="{!contact.School__r.Lastname__c}"/>   
           <apex:actionstatus startText="Getting Details" id="stat"></apex:actionstatus>
       </apex:pageblockSection>
                         
         
    </apex:pageBlock>
</apex:form>
</apex:page>

Controllor

public with sharing class RelatedController1
{
 private ApexPages.StandardController stdCtrl;
  
 public RelatedController1(ApexPages.StandardController std)
 {
  stdCtrl=std;
 }
  
 public void SchoolPopulated()
 {
  Contact cont=(Contact) stdCtrl.getRecord();
  if(!String.isBlank(cont.School__r.Id))
  {
      cont.School__r=[select First_Name__c,Lastname__c from School__c where id=:cont.School__r.Id];
  }
  else
   {
       cont.School__r=null;
   }   
 }
}

Here Contact is child and School__c is parent.

so you need to pass a parameter in the URL like this:
https://test.salesforce.com/apex/YOURPAGENAME?id=CONTACTID

Replace "YOURPAGENAME" with your actual VF Page name
Replace "CONTACTID" with an actual Contact record ID.
