To create a property with automatically assigned font UI-TypeEditor, you have to create a public property in your custom class with type of font, not string. public Font MyFont { get {return this.m_myFont; } set {this.m_myFont = value; } } Visual Studio is using the pre-created FontEditor UI-TypeEditor from the System.Drawing.Design assembly. You have to implement your property like mentioned. Or you have to implement a custom FontEditor UI-TypeEditor. If you do that, you have to derive from UITypeEditor or FontEditor class. Bye Frank Loizzi Dortmund, Germany Hello Frank, I don't want to create Font type property but Custom type property which is serialized by designer like Font property or Size property. For this properties desinger creates creates code which sets value of property wich new created object eg. this.Size = new Size(10,10); I wont my own class which will be serialized by designer like mentioned.

Add this above the public property: [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] That's all you have to do. Bye Frank Loizzi Dortmund, Germany I have this attribut applied to property. But this does not help. I see property in properties window but I cannot edit it. I can't even expand it like font property to see object details. > Am Tue, 26 Sep 2006 23:20:01 -0700 schrieb zofcentr: > [quoted text clipped - 12 lines] > Frank Loizzi > Dortmund, Germany Create a custom TypeConverter, and when an InstanceDescriptor type is requested, create an InstanceDescriptor describing how to serialize your object. Associate the TypeConverter with your class with an attribute.

Do YOU know maybe how to change behavior of designer serialization. Normaly serializer creates code like that : myComponent.CustomProperty = new CustomPropertyData(.....); I would like to avoid creating complex constructor for every comlex property object and have a code like below : myComponent.CustomProperty = new CustomPropertyData();<- default constructor myComponent.CustomProperty.FirstName = "John"; myComponent.CustomProperty.LastName = "Smith"; Thanks in advance zofcentr > Create a custom TypeConverter, and when an InstanceDescriptor type is > requested, create an InstanceDescriptor describing how to serialize your [quoted text clipped - 30 lines] > >> Frank Loizzi > >> Dortmund, Germany Hi, The third parameter to the InstanceDescriptor constructor is a boolean called isComplete. Set that to false and the code generator will create a local variable, then use the usual DefaultValue and ShouldSerialize logic to determine if the property values must be serialized.
