Description

How to visualize a field as a Check Box on a form.

Uses

This Visualization type is useful for a Field that is used as a Boolean(TRUE\FALSE).

Through the Field Component source add a Picklist visualization ( PRIM_EVPL ) and a Picklist. Note that these are separate classes in the Field source. Add two picklist items ( Yes and No) to the Picklist and change the Appearance property of the PRIM_EVPL to CheckBox. Save the field and use the VisualPicklist class on a form.

Appearance

Note:

Clicking the check box will set the corresponding value for the field from the picklist items. Values are chosen from the following rule:

• Checkbox Unchecked = First picklist item value
• CheckBox Checked = Last PicklistItem value
• CheckBox grayed = Any picklistItem between first and last or an invalid value. (eg Changing the value of the field to a value that is not the first or last item in the picklist will result in the check box being grayed.)
