PropertyValueChanged event

[David W. Simmonds]

I have a custom object that I use in a PropertyGrid as seen below. It
presents an elipsis button that when clicked brings up a custom modal
dialog. When I make a change in the property, the PropertyValueChanged event
never gets fired. I have other properties in the PropertyGrid that do fire
the event. Is there anything special that I need to do to have the event
fired?

[System::ComponentModel::EditorAttribute(__typeof(C PictureEditor),
__typeof(System::Drawing::Design::UITypeEditor))]
[System::ComponentModel::TypeConverterAttribute(__t ypeof(CPictureConverter))
]
[Serializable]
public __gc class PictureObj : public
System::Runtime::Serialization::ISerializable
{
private:
CPicture* m_pPicture;
public:
PictureObj()
{
m_pPicture = new CPicture;
}
~PictureObj()
{
delete m_pPicture;
}
PictureObj(System::Runtime::Serialization::Seriali zationInfo *si,
System::Runtime::Serialization::StreamingContext sc)
{
m_pPicture = new CPicture;
SetObjectData(si, sc);
}
void SetPicture(CPicture* pic) { *m_pPicture = *pic; }
CPicture* GetPicture() { return m_pPicture; }
void GetObjectData(System::Runtime::Serialization::Seri alizationInfo
*si,

System::Runtime::Serialization::StreamingContext sc);
void SetObjectData(System::Runtime::Serialization::Seri alizationInfo
*si,

System::Runtime::Serialization::StreamingContext sc);

__property IPicture* get_Picture() { return m_pPicture->m_pImage; }
__property void set_Picture(IPicture* value) { m_pPicture->m_pImage =
value; }
__property System::String* get_ImageExt() { return new
System::String(m_pPicture->m_strImageExt); }
__property void set_ImageExt(System::String* value) {
m_pPicture->m_strImageExt = value; }
};

Hi David,

Is this the complete code? I don't see the event handler nor the event
hookup. If you have those, please post them as well.
If you don't have them, you need to get the event hooked up.

Thanks,

Hi,

You need to create your own class that derived from UITypeEditor and
override the EditValue method. In that method open the form and when you
finish return the value to the Value parameter. You should also override
the GetEditStyle to set the modal mode.

This, at least, works for me.
