The Source area allows you to specify a database field to be associated with the control. If this is done some of the other properties are always taken from the data dictionary and so are removed or disabled in the dialog.
The format area allows you to specify various formatting options for the data in the edit control. This format infomation is dependent on the type of the field. For non database fields you need to specify the type of data the field will contain.
The validation area (within the format area) allows you to specify low,high and default values for the field (or a subset, depending on the data type). The low and high values are used to validate the data entered into the field. The default value is only used when the field has the clearfirst behaviour set, and the dialog is also invoked with the clearfirst flag set to TRUE.
