Property Value

Type	Default	Description
String	*null*	An object implementing the ICustomExtractDriver interface that specifies a custom driver.

Remarks

By default, the DashboardExtractDataSource stores data within a file. If necessary, you add a custom logic for writing/reading extract data by implementing the ICustomExtractDriver interface. After you have implemented a custom driver, you can use it in two ways.

• To use a custom driver across all data extracts, assign its instance to the ExtractDriverStorage.DefaultDriver property.
• To use a custom driver for the specified data extract, register this driver in the ExtractDriverStorage using the ExtractDriverStorage.RegisterCustomDriver method and assign its name to the DriverName property.

Note

Note that the value of DriverName is saved to the dashboard XML definition. This allows you to determine the driver name when opening the dashboard supplied with data using DashboardExtractDataSource with a custom driver.
