A developer can easily conditional control the availability of one or more parts on a form without having to write a Layout Control. Each Form Template Parts record includes Disabled Behavior and Run Mode fields that determine the conditions under which a particular part should be available on a form, as described below:

• When a Form Template Part has a Run Mode of All, the part is always visible on a form.
• When a Form Template Part has a Run Mode of New Only and a Disabled Behavior of Disable, the specified part is only available on new records. Once the record has been saved, the field or tab becomes unavailable.
• When a Form Template Part has a Run Mode of New Only and a Disabled Behavior of Hide, the specified part is only available on new records. Once the record has been saved, the field or tab is automatically removed from the form and is no longer available.
• When a Form Template Part has a Run Mode of Saved Only and a Disabled Behavior of Disable, the specified part is only available for saved records. The field or tab is grayed out and unavailable on new records and automatically becomes available once the record has been saved.
• When a Form Template Part has a Run Mode of Saved Only and a Disabled Behavior of Hide, the specified part is only available for saved records. The field or tab is not visible on new records and is automatically added to the form once the record has been saved.
