Remarks
This property is used to determine whether the current object can be used as a source of one or more lists of data. Data source controls encapsulate their lists of data as DataSourceView objects; therefore, when associated with one or more DataSourceView objects, a DataSourceControl control represents a list source object and the property returns true
.
This property calls the static ListSourceHelper.ContainsListCollection method to determine whether the current data source control can be used as a source of data. The ListSourceHelper class determines whether the GetViewNames method returns a valid collection of view names. If it does, this property returns true
. If GetViewNames returns null
, which is the default implementation of the DataSourceControl class, the method returns false
.
