Is there a way to manipulate two bound properties upon loading them?

[Former Member]

The title of this post doesn't really explain well. I want a placeholder property to contain the returned value of the quantity ordered, minus the quantity received, and I'm trying to do it in the controller.

qtyO = new sap.m.Input({
                    type: sap.m.InputType.Number,
                    placeholder: "{QtyOrdered}" - "{QtyReceived}",
                    width: "100px",
                    enabled: false,
                    change: function (evt) {
                        refreshList(evt);
                    }
                }),

I think what I'm trying here isn't following the strings as paths, as it returns NaN. Is there a simple way to doing this? Or would it be better done on the backend?

Hi Jackie,

You could use calculated fields.

Find below example of above code edited
