DataSourceConverter.IsValidDataSource(IComponent) Method

Definition

Indicates whether the specified component is a valid data source for this converter.

protected:
 virtual bool IsValidDataSource(System::ComponentModel::IComponent ^ component);
protected virtual bool IsValidDataSource (System.ComponentModel.IComponent component);
abstract member IsValidDataSource : System.ComponentModel.IComponent -> bool
override this.IsValidDataSource : System.ComponentModel.IComponent -> bool
Protected Overridable Function IsValidDataSource (component As IComponent) As Boolean

Parameters

component
IComponent

The component to check as a valid data source.

Returns

true if component implements IEnumerable or IListSource; otherwise, false.

Remarks

The GetStandardValues method uses the IsValidDataSource method to determine the components that are available as standard accessible data sources. For the DataSourceConverter class, a valid data source is a component that implements the IEnumerable or IListSource interface.

Notes to Inheritors

Custom data source converters can derive from the DataSourceConverter class, and override the IsValidDataSource(IComponent) method, to test for the interface implementations that are required to use a component as a data source.
