Hello.
I'm facing the exact problem described here:
http://groups.google.com/groups?hl=...&lr=&q=TypeConverter%3A%3AGetProperties&meta=
I made a ExpandableObjectConverter subclass but its GetProperties method is
not called when my object is set as a Converter of PropertyDescriptor. The
thread above gives a good explanation of the problem, but the solution is
not described there!
Does anyone have an idea.
Bellow is the code of my derived class. If I try to use 'override' on
GetProperties declarations, the compiler says there's not a compatible
declaration on base class.
#pragma once
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System:iagnostics;
public ref class TExpandableProperty : public ExpandableObjectConverter
{
public:
TExpandableProperty();
virtual PropertyDescriptorCollection^
GetProperties(ITypeDescriptorContext^, Object^, Attribute^ attributes)
{return GetProperties();}
virtual PropertyDescriptorCollection^ GetProperties(Object^) {return
GetProperties();}
virtual PropertyDescriptorCollection^
GetProperties(ITypeDescriptorContext^, Object^) {return GetProperties();}
virtual PropertyDescriptorCollection^ GetProperties();
virtual bool GetPropertiesSupported(ITypeDescriptorContext^) override
{return GetPropertiesSupported();}
bool GetPropertiesSupported() {return true;}
bool AddProperty(PropertyDescriptor ^propertyDescriptor);
property bool ReverseProperties {
void set(bool newValue){reverseProperties=newValue;}
}
protected:
private:
PropertyDescriptorCollection ^propertyCollection;
PropertyDescriptorCollection
^ReversePropertyDescriptorCollection(PropertyDescriptorCollection^
propertyDescriptorCollection);
bool reverseProperties;
};
Thanks in advance for any help.
