ControlPropertyNameConverter.GetStandardValues(ITypeDescriptorContext) 方法

定义

与格式上下文一起提供时,在实现 IDesignerHost 的设计器中返回控件的属性名集合。Returns a collection of property names for the control within a designer that implements IDesignerHost when provided with a format context.

public:
 override System::ComponentModel::TypeConverter::StandardValuesCollection ^ GetStandardValues(System::ComponentModel::ITypeDescriptorContext ^ context);
public override System.ComponentModel.TypeConverter.StandardValuesCollection GetStandardValues (System.ComponentModel.ITypeDescriptorContext context);
override this.GetStandardValues : System.ComponentModel.ITypeDescriptorContext -> System.ComponentModel.TypeConverter.StandardValuesCollection
Public Overrides Function GetStandardValues (context As ITypeDescriptorContext) As TypeConverter.StandardValuesCollection
