Update the date filed on pagelevel

I have a date filed(Datefiled12) which is displayed in Visualforce page and a formula filed(Updatedate) of datetype "date", whenever Datefiled12  is changed on visual force page then  Updatedate has to updated  with value equal to  Datefiled12 +4 days.

 

 

EG:

when user select the below value on visualforce page

Datefiled12  = 1/5/2012

 

then Updatedate = 1/9/2012

 

Can it be possible on page level without any button click?

    public Pagereference assignDate(){
    psDisp.New_Date__c = psDisp.closeDate + 5;
    return null;
    }

}

 While testing u need to create a new field new date on opportunity. Also enter all the field values(Name, stage etc) before you test for the same.

Are u displaying the formula field on the VF page as well. In case you are the change will not show on the page until you save the record.

One thing that can be done is show the users a dummy field on the VF page, rerender the field once the user selects some value on the original date field and then in the database the formula field will calculate the value on its own.

 

let me know in case you need more on this

Yes, im displaying the formula filed on VF page. 

 

you mean, rerender the page once the original date field updated.
