Propertygrid: How to show and edit "aggregated" property

Sometimes we need to edit  aggregated property - I mean the property that represents object with few properties .The simple way to do this - we can use TypeConverter with ExpandableObjectConverter as shown in the example

 

 

[TypeConverter(typeof(ExpandableObjectConverter))]
public class FullName
{
    private string _FirstName;
    private string _LastName;


    public FullName(string _FirstName, string _LastName)
    {
        this._FirstName = _FirstName;
        this._LastName = _LastName;
    }

    [DisplayName("First Name")]
    [Description("First name of the person")]
    public string FirstName
    {
        get
        {
            return _FirstName;
        }
        set
        {
            _FirstName = value;
        }
    }

    [DisplayName("Last Name")]
    [Description("Last name of the person")]
    public string LastName
    {
        get
        {
            return _LastName;
        }
        set
        {
            _LastName = value;
        }
    }


    ///<summary>
    ///Returns a <see cref="T:System.String"></see> 
    /// that represents the current <see cref="T:System.Object"></see>.
    ///</summary>
    ///
    ///<returns>
    ///A <see cref="T:System.String"></see> 
    /// that represents the current <see cref="T:System.Object"></see>.
    ///</returns>
    ///<filterpriority>2</filterpriority>
    public override string ToString()
    {
        return _FirstName + " " + _LastName;
    }
}

 

 

[DisplayName("Full Name")]
[Description("Full name of the person")]
public FullName FullName
{
    get
    {
        return _FullName;
    }
    set
    {
        _FullName = value;
    }
}

Result - the editor for aggregated object
