    <apex:form id="formId">
        <apex:pagemessages ></apex:pagemessages>
        <apex:pageBlock title="Service Edit" id="pgBlkId">
      <apex:pageBlockButtons >
        <apex:commandButton action="{!Save}" value="Save"/>
                <apex:commandButton action="{!Cancel}" value="Cancel"/>
      </apex:pageBlockButtons>
      <apex:pageBlockSection title="Service Information" collapsible="false" id="pgBlkSecId">
                <apex:inputField value="{!ser.Name}" taborderhint="1" />
                <apex:inputField value="{!ser.Type__c}" taborderhint="4"/>
                <apex:inputField value="{!ser.SKU__c}" taborderhint="2">
                    <apex:actionSupport event="onchange" action="{!getautopopultevalue}" />
    	         </apex:inputField>
                
                <apex:inputField value="{!ser.Hourly_Amount__c}" taborderhint="5"/>
                <apex:pageblockSectionItem >
                    <apex:outputLabel > Proposal </apex:outputLabel>
                    <apex:outputPanel >
                        <div class="requiredInput">
                            <div class="requiredBlock"></div>
                            <apex:inputField value="{!ser.Proposal__c}" required="false" taborderhint="3"/>
                        </div>
                    </apex:outputPanel>
                </apex:pageblockSectionItem>
            </apex:pageBlockSection> 
            <apex:pageBlockSection columns="1"> 
                <apex:pageblockSectionItem />
          <apex:inputField value="{!ser.Description__c}" taborderhint="6"/>
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

 

Controller class :  

 

public class ServiceExtController {
    public Services__c ser {get;set;}
    public ServiceExtController (ApexPages.StandardController stdController){
        this.ser = (Services__c)stdController.getRecord();
    }  
  
    public void getautopopultevalue(){
       
        // checking lookup field is not null
        if( ser.SKU__c != null ){
            
           // fetching values from sku object we need to autopopulate sku values on our vf page 
            SKU__c skuValue =  [select Id,Name,Long_description__c,Price__c,Short_Description__c,Type__c from SKU__c 
                                where Id =: ser.SKU__c limit 1];
            
           
            // assigning value to ser that is of type service. ser is get set variable of our vf page 
            
            ser.Type__c = skuValue.Type__c;
            ser.Description__c = skuValue.Long_description__c;
            ser.Hourly_Amount__c = skuValue.Price__c;
        }else{
            ser.Type__c = '';
            ser.Description__c = '';
            ser.Hourly_Amount__c = null;
        }
    }
}
