LookupValue Procedure
Shows a lookup page for a selected field in a given table.
If the field specified by FieldNo has a table relation to a table that has a lookup page, this will be shown.
If the field is an option or enum, a lookup for enum values will be shown.
Signature
LookupValue(var RecRef: RecordRef; FieldNo: Integer; var FieldValue: Text) : Boolean
Parameters
var RecRef RecordRef
The table that contains FieldNo, populated with any values that are needed to determine the table relation.
FieldNo Integer
The number of the field in RecRef that has one or several table relations, or that is of the Option or Enum data types.
If the field has conditional table relations, then RecRef must be populated with the values that are needed to identify the table relation.
var FieldValue Text
Returns the selected value, formatted as XML.
If this parameter has an input value, this will be used to try to position the selected record when the page list is opened.
The input value must also be formatted as XML, with the help of Format(Value, 0, 9).
Returns
Boolean
This function returns true if the user has selected a record and FieldValue
contains the value of the related field.
false is returned if the user cancels the lookup, if no field relation could be found for
the field specified by FieldNo or if the field is not of the Option or Enum data types.
