Editing custom types in property grid

Question

I have a class MinMax which among other things contains this:

public class MinMax
{
    private float m_min = 0;
    private float m_max = 1;
    public override string ToString()
    {
        return m_min + " " + m_max;
    }
}

I also have another class SomeClass with a property of this type:

public MinMax Something
{
    get
    {
        return m_something;
    }
    set
    {
        m_something = value;
    }
}

When I put an object of type SomeClass in a property grid, Something is correctly displayed but for natural reasons I'm not able to edit the value.

I know I can create a custom type editor and show a custom form to edit it, but I would like to edit the displayed string directly.

My first solution was to return a string from Something instead but I have other code that needs this property to be returned in it's native format.

Is thera any other convenient solution that will let med edit the value directly as a string in the propertygrid?

Maybe you're looking for a Custom UITypeEditor :

For completeness have a look also to TypeConverter ,
that can be used to allow simple editing (eg from-to strings) without the need of a custom UITypeEditor :
