Drop From Class Library (Source Code)
Adds fixed values to items in a C5 or C55 drop list using a string FROM attribute. Like a Radio Buttons in an Option control, values returned by the drop may differ from what is displayed. When applications are internationalized, it extends the value element now available in C55.
- Screen Space. A drop use less screen space than an OPTION with RADIO buttons with VALUEs.
- Numeric and Abbreviated Values. Drops can have abbreviated string or numeric values different from their what is displayed.
- Retain String Dependent Code. You can retain string dependent code even if drops are translated.
- Limit Translation to Display String Only. Translation can be limited to the display string without including the value in the translation file. This both safer and requires fewer translations.
