This read-write property determines the aaHistClientTrend control’s default retrieval style. This setting applies to all tags in a trend whose retrieval style is set to Style selected at option level.

Syntax

aaHistClientTrend.RetrievalOptionsRetrievalStyle = string;

Result = aaHistClientTrend.RetrievalOptionsRetrievalStyle;

Remarks

You must provide the retrieval style name for the current locale as it is defined in the retrieval style document. For more information, see Location and Structure of Retrieval Styles. To find out how many retrieval styles are available in the control, use the RetrievalOptionsNumStyles property. To determine the name of a retrieval style if you know its position in the list of available styles, use the RetrievalOptionsGetStyle method.

Valid values: Custom style (or the translated equivalent for the current locale) and any retrieval style name that is defined for the current locale in the retrieval style document. Values are case-sensitive. If no style names at all are available for the current locale, use the name for the en locale. The default style is BestFit-5 (or the translated equivalent).
