Visualforce CommandButton Auto-Refresh Parent Standard Page on Page Save

Question

I have a Visualforce (child page) stored within a Standard Page layout (Opportunity parent standard page) which calls a custom controller "Save" method.

I would like for the parent page to refresh/reload automatically after the "Save" Command button is clicked on the child VF page. Is this possible?

Visualforce:

<apex:commandButton value="Save" action="{!saveConditions}" disabled=" 
{!if((Opportunity.ApprovalStatus__c ='' || Opportunity.ApprovalStatus__c 
='Recalled' || Opportunity.ApprovalStatus__c ='Rejected') ,'false','true')}" 
rendered="{!Conditions.size>0}" status="actStatusId" reRender="pgBlckId" />  

Controller (saveConditions) method:

    public pageReference saveConditions(){
    try {
        List<Pricing_Condition__c> temp = new List<Pricing_Condition__c>();
        for(ConditionWrapper A : Conditions) temp.add(A.Condition); 
        upsert temp; 

    //}catch(dmlException E){ ApexPages.addMessage(new 
    ApexPages.Message(ApexPages.Severity.ERROR, e.getMessage())); }  
    } catch (DMLException ex){

    String errorMessage = ex.getMessage();
    Integer occurence;
    if (ex.getMessage().contains('FIELD_CUSTOM_VALIDATION_EXCEPTION')){
    occurence = errorMessage.indexOf('FIELD_CUSTOM_VALIDATION_EXCEPTION,') + 
    34;
    errorMessage = errorMessage.mid(occurence, errorMessage.length());
    occurence = errorMessage.lastIndexOf(':');
    errorMessage = errorMessage.mid(0, occurence);
    }
        else {
                errorMessage = ex.getMessage();
                }
        ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 
        errorMessage));
}
return null;

}

There is no straight forward way by which you can do that. But there is a workaround for that where we can set window.top.location.href to refresh the entire page.

Inline visualforce page

<apex:page standardController="Opportunity" extensions="OpportunityExtn" > 
    <apex:form > 
        <apex:commandButton value="Save" action="{!saveConditions}" disabled="{!if((Opportunity.ApprovalStatus__c ='' || Opportunity.ApprovalStatus__c ='Recalled' || Opportunity.ApprovalStatus__c ='Rejected') ,false,true)}"  status="actStatusId" rendered="{!conditions.size>0}" reRender="pgBlckId,redirectPanel" /> 
        <apex:outputPanel id="redirectPanel" > 
            <apex:outputText rendered="{!shouldRedirect}"> 
                <script type="text/javascript"> 
                    window.top.location.href = '{!redirectUrl}'; 
                </script> 
            </apex:outputText> 
        </apex:outputPanel> 
    </apex:form> 
</apex:page>

Controller extension

public class OpportunityExtn { 
    private ApexPages.StandardController stdController; 
    public String redirectUrl {public get; private set;} 
    public Boolean shouldRedirect {public get; private set;} 
    public OpportunityExtn(ApexPages.StandardController stdController) { 
        this.stdController = stdController; 
        shouldRedirect = false; 
    } 
    public PageReference saveConditions() { 
        try{
            shouldRedirect = true; 
            redirectUrl = stdController.view().getUrl(); 
            //All your save logic in try
        } catch (Exception ex){               
            shouldRedirect = false; 
            redirectUrl ='';
            //All the catch logic
        }              
        return null; 
    } 
}
