FilterDataSource Method (WebScheduleDbProvider)

Verifies the DataSourceControl meets the WebSchedule data provider's compatibility requirements.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Function FilterDataSource( _
   ByVal source As DataSourceControl _
) As Boolean

C#

protected virtual bool FilterDataSource( 
   DataSourceControl source
)

Parameters

source

An instance derived from DataSourceControl.

Return Value

True if source is acceptable; otherwise false.

Remarks

This method is called when resolving the DataSourceID property at run-time.

If you use this method to capture a reference to the DataSourceControl, then you should be aware that any changes you make to the DataSourceControl instance may not have an effect on the WebSchedule data provider.

Inheritors must call the base implementation of the FilterDataSource method and logically-AND the outcome with the results of their own processing before returning the result, otherwise an overridden implementation may allow to pass through a DataSourceControl unable to meet the requirements of a WebSchedule data provider. This could lead to an exception being later thrown.
