FieldRef.GetRangeMax() Method
Version: Available or changed with runtime version 1.0.
Gets the maximum value in a range for a field.
Syntax
Value := FieldRef.GetRangeMax()
Note
This method can be invoked using property access syntax.
Parameters
FieldRef
Type: FieldRef
An instance of the FieldRef data type.
Return Value
Value
Type: Any
Remarks
This method is like the GetRangeMax Method (Record) method.
Example
The following example opens the Customer table as RecordRef variable, creates a FieldRef for the first field (No.) and stores the reference in the MyFieldRef variable. The SetFilter Method (FieldRef) sets a filter that selects records in the range 10000 to 40000 from the No. field. The GetRangeMax method retrieves and stores the maximum value that was set in the filter, stores the value in the varMax variable and displays it in a message box. The varMax variable contains 40000 which is the maximum value that is set in the filter.
var
MyFieldRef: FieldRef;
CustomerRecref: RecordRef;
varMax: Text;
Text000: Label 'The maximum value in the filter is %1.';
begin
CustomerRecref.Open(Database::Customer);
MyFieldRef := CustomerRecref.Field(1);
MyFieldRef.SetFilter('10000..40000');
varMax := MyFieldRef.GetRangeMax();
Message(Text000, varMax);
end;
