Default Values (v6.x)

Attributes

Each XML node requiring a default value requires specialized attribute to set the rules for cascading and setting default values automatically.

DefaultSource

The source table, column and record which triggers use of the default value. Uses the form "TableName.FieldName,RecordId", e.g., "Encounters.EncDateText,1"

Additionally, if the node does not specify a value for DefaultValue, the value of the field specified in DefaultSource is used as the default value.

DefaultValue

A static default value. If none set, use Source value.

RequireSiblings

True or false if the field requires a sibling value before setting the DefaultValue.

TriggeredBySiblings

If True, setting any of the field's siblings will activate the DefaultValue. Defaults to "True".

TriggeredByChildren

If True, when child control value set, activate parent default value logic. Defaults to "True"

Examples

Static Value

In the following example, the LabTest field will default to "PSA" and the LabQuality will default to "STD" when a value is entered for any field in the LabTest record.

   <LabTests RecordId="1">
       <LabDate></LabDate>
       <LabDateText></LabDateText>
       <LabTest NotNull="True" DefaultValue="PSA"></LabTest>
       <LabResult></LabResult>
       <LabUnits></LabUnits>
       <LabQuality DefaultValue="STD"></LabQuality>
   </LabTests>

Trigger Static Value

In the following example LabTest field gets populated with "PSA" and the LabQuality field get populated with "STD" when the user enters a chief complaint.

   <LabTests RecordId="1">
       <LabDate></LabDate>
       <LabDateText></LabDateText>
       <LabTest NotNull="True" DefaultSource="Encounters.EncChiefComplaint,1" DefaultValue="PSA"></LabTest>
       <LabResult></LabResult>
       <LabUnits></LabUnits>
       <LabQuality DefaultSource="Encounters.EncChiefComplaint,1"  DefaultValue="STD"></LabQuality>
   </LabTests>

Copy Dynamic Value (activate source)

In the following example, the LabTest date (LabDate) gets populated with the Encounter date (EncDate) when the user selected an Encounter date.

   <LabTests RecordId="1">
       <LabDate DefaultSource="Encounters.EncDate,1" ></LabDate>
       <LabDateText DefaultSource="Encounters.EncDateText,1" ></LabDateText>
       <LabTest NotNull="True"></LabTest>
       <LabResult></LabResult>
       <LabUnits></LabUnits>
       <LabQuality></LabQuality>
   </LabTests>

Copy Dynamic Value (activate sibling)

In the following example, the LabTest date (LabDate) gets populated with the Encounter date (EncDate) ONLY when a field in the LabTest record has a value.

   <LabTests RecordId="1">
       <LabDate DefaultSource="Encounters.EncDate,1" TriggeredBySiblings="True></LabDate>
       <LabDateText DefaultSource="Encounters.EncDateText,1" TriggeredBySiblings="True"></LabDateText>
       <LabTest NotNull="True"></LabTest>
       <LabResult></LabResult>
       <LabUnits></LabUnits>
       <LabQuality></LabQuality>
   </LabTests>
