In Mail & Deploy, expressions can be used to supply values to certain functions; expressions can either return constant values (see Constant Values), dynamic values (see Dynamic Values) or values calculated from constant and/or dynamic values (see Calculations).
Example: You want to filter a datasource field (see Filter Datasource Field Action). The list of values you want the field to be filtered to is a list of expressions, which will be evaluated just before the field is filtered.
The language in which expressions are written in Mail & Deploy, is Visual Basic .NET; however, in most cases you will not be required to have a deeper knowledge of the language.
Expressions are edited in an expression editor, which provides the following buttons:
![]() | Click this button to choose a built-in value to insert. |
![]() | Click this button to open a larger expression editor, which gives you more space to edit the expression. |
![]() | Click this button to open an editor to edit the module (see Module) of the current repository. |
