ComponentDesigner.PreFilterAttributes Method
Allows a designer to add to the set of attributes that it exposes through a TypeDescriptor.
[Visual Basic] Protected Overridable Sub PreFilterAttributes( _ ByVal attributes As IDictionary _ ) [C#] protected virtual void PreFilterAttributes( IDictionary attributes ); [C++] protected: virtual void PreFilterAttributes( IDictionary* attributes ); [JScript] protected function PreFilterAttributes( attributes : IDictionary );
Parameters
- attributes
- The attributes for the class of the component.
Remarks
This method provides a way to add items to the dictionary of attributes that a designer exposes through a TypeDescriptor.
The keys in the dictionary of attributes are the type identifers of the attributes, as specified by the value of their TypeId property. The objects are of type PropertyDescriptor. This method is called immediately before PostFilterAttributes.
Notes to Implementers: You can directly modify the dictionary that is accessible through the attributes parameter, or you can leave it unchanged. If you override this method, call the base implementation before you perform your own filtering.
