TdxRangeControlDateTimeClientProperties.Scale Property

Specifies the scale displayed by the range control‘s ruler provided by the date/time client.

Declaration

delphi

property Scale: TdxRangeControlDateTimeScale read; write;

Property Value

Type
TdxRangeControlDateTimeScale

Remarks

This property specifies the measurement unit corresponding to the minimum date/time range that can be selected by using a range control integrated with the date/time client. To change the scale displayed on the range control’s ruler, you can assign one of the scales supported by the client to the Scale property:

Value	Scale’s Measurement Unit	Synchronized with the Property Value
Scales.Day	rcduDay	Scales.Day.Active
Scales.Hour	rcduHour	Scales.Hour.Active
Scales.Minute	rcduMinute	Scales.Minute.Active
Scales.Month	rcduMonth	Scales.Month.Active
Scales.Quarter	rcduQuarter	Scales.Quarter.Active
Scales.Week	rcduWeek	Scales.Week.Active
Scales.Year	rcduYear	Scales.Year.Active

The following code example sets the minimum selectable date/time range to one month:

Delphi
C++

delphi

var
  ADateTimeProperties: TdxRangeControlDateTimeClientProperties;
//...
  ADateTimeHeaderProperties := dxRangeControl1.ClientProperties as TdxRangeControlDateTimeClientProperties;
  ADateTimeProperties.Scale := ADateTimeProperties.Scales.Hour;

cpp

TdxRangeControlDateTimeClientProperties *ADateTimeProperties;
//...
  ADateTimeProperties = dynamic_cast<TdxRangeControlDateTimeClientProperties*>(dxRangeControl1->ClientProperties);
  ADateTimeProperties->Scale = ADateTimeProperties->Scales->Hour;

Alternatively, you can set the corresponding synchronized property to True.

Note

To identify the minimum range that can be selected by using the range control integrated with the date/time client, use the Scale.ScaleUnit property.
