Readonly property on PropertyGrid

[Luis Barreira]

I hava a situation where I have a class that contains objects os other classes that are to be readonly (the whole thing is initialized in the constructor, and the gris is used only to show the results). The problem is that the TypeConverters for some of the inner objects are allowing to edit the object: using System; using System.ComponentModel; namespace PropertyTest { public class SimpleClass { private NestedClass _xy; private int _z; public NestedClass XY { get { return _xy; } } public int Z { get { return _z; } } public SimpleClass() { _xy = new NestedClass(1, 2); _z = 3; } } [TypeConverter(typeof(NestedClassConverter))] public class NestedClass { private int _x; private int _y; public int X { get { return _x; } set { _x = value; } } public int Y { get { return _y; } set { _y = value; } } public NestedClass(int x, int y) { _x = x; _y = y; } } public class NestedClassConverter : ExpandableObjectConverter { public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType) { if (destinationType == typeof(NestedClass)) return true; return base.CanConvertTo(context, destinationType); } public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, Type destinationType) { if (destinationType == typeof(System.String) && value is NestedClass) { NestedClass nc = (NestedClass)value; return nc.X.ToString() + "," + nc.Y.ToString(); } return base.ConvertTo(context, culture, value, destinationType); } } } If I create an object of type SimpleClass, I want the property of type NestedClass to be readonly on the propertygrid. How can I do that? Luis Barreira

[ReadOnly]
public NestedClass XY
{
get { return _xy; }
}

xacc.ide-0.1.1.10 - now with AutoComplete(kinda) :)

I've tried that, and I also tried declaring the variable as private readonly NestedClass _xy; but it still let's me edit XY's properties...

Maybe apply the typeconvertor to the property instead of the type, and the ReadOnly attribute.
