The accounts receivable=price * number;
At this time of the xaml binding part of the accounts receivable and accounts receivable corresponding field such as the field name is Receivables
We can change the definition of Receivables attribute
Public double Receivables {get=& gt; Receivables; The set=& gt; Receivables=value; }
Instead of
Public double Receivables {get=& gt; Ticket number *; The set=& gt; Receivables=value; }

Second, you can also use more binding, MultiBinding, but need to use the Convert, custom Convert.
