Edit-Combo Control - Specifying a Different Stored Value from the Display Value
Dropdownbox controls allow you to specify that the stored value is different from the display value.
For example, the control might display a 'ProductName' but the stored value in the control might be the 'ProductId'.
Edit-combo box controls can now also be configured to store a different value than their display value, just like a Dropdownbox control.
The benefit of using an Edit-combo control over a Dropdownbox control is that you can display multiple columns of data in the choice list and you can dynamically populate the choices in the list with an Ajax callback every time the control is opened.
In this video we show how to configure an Edit-combo control to store a different value from its display value.
