Subtotalizing a from grid editable

Hi, how i can totalizing a grid editable, i need show in footer or header Total:. sum(field_value).
I have in event onload [v_title] = sum of field value. and works fine.

But i need everytime that a user update a row the footer refresh too.

I tried in onloadrecord, but it not refresh.

any idea?

Guess I am not smart enough…

I do this for one of my applications… But It is a summary of the dollars associated with the records details.

I tried doing it, but since when you use an editable grid when you update the record it is only refreshing the record not everything.
I got it to work if I refreshed the page using F5 but I cannot get the page to refresh using scriptcase and I dont know javascript…

But what I did, is created a php method to sum a fields value in the database and then on the OnAfterUpdate,OnAfterInsert and OnAfterDelete called that php method…

Like I said it updated but only the record I was on.

I had created a field called sum in case that is lost in translation…
