TdxRangeControlDateTimeHeaderClientProperties Class

A Date/Time Header range selection and visualization model.

Declaration

TdxRangeControlDateTimeHeaderClientProperties = class(
    TdxRangeControlCustomDateTimeHeaderClientProperties
)

Remarks

The Date/Time Header range model allows you to select ranges of date/time values by using one or more predefined scales graduated in various measurement units. Unlike Date/Time, the Date/Time Header model shows scale(s) at the top border of the range control.

The TdxRangeControlDateTimeHeaderClientProperties class does not introduce any new functionality except for publishing properties from its ancestor classes and initializing the ScaleIntervalMinWidth property to 30, to underpin the Date/Time Header range model’s design.

For detailed information on class members providing the data range model’s core functionality, refer to the TdxRangeControlCustomClientProperties class description.

A TdxRangeControlDateTimeHeaderClientProperties object is referenced by the range control’s ClientProperties property. To access the members specific to the Date/Time Header data range model, cast the ClientProperties property to the TdxRangeControlDateTimeHeaderClientProperties class.

To assign a Date/Time Header data range model to the range control, use its ClientPropertiesClassName or ClientPropertiesClass property. For additional information, refer to the Data Range Selection and Visualization Models topic.
