Format Strings

Format Strings can be used to tell dbFront how to format and display numeric and date field types within Grids and Reports. Format Strings won't be applied when the field is displayed in Forms because a format string may hide information or make it difficult to edit.

dbFront uses the .Net formatting engine. Below are several charts detailing the formatting options. Additional References are below:
