Custom control properties are not saved in designer

Hello

I have a class with several custom properties:

    public class ComboBoxColumn : DataGridViewColumn
    {
        [Category("Data"), DescriptionAttribute("My custom propety"), Browsable(true)]
        public BindingSource DataSource
        {
            get;
            set;
        }

        [Category("Data"), DescriptionAttribute("My custom propety"), Browsable(true)]
        public string DisplayMember
        {
            get;
            set;
        }

        [Category("Data"), DescriptionAttribute("My custom propety"), Browsable(true)]
        public string ValueMember
        {
            get;
            set;
        }

        public ComboBoxColumn()
            : base(new ComboBoxCell())
        {
        }

        public override DataGridViewCell CellTemplate
        {
            get
            {
                return base.CellTemplate;
            }
            set
            {
                base.CellTemplate = value;                
            }
        }
    }


I see my attributes in designer, but when I set the value for those properties, close the designer (pressing OK) and then reopened it, values are no longer there - I see only empty fields. Why are my values not saved?

Greetings, Frenky

Are you talking about displaymember, valuemember properties? Try using a private variable and get set it.

You will have to use the DesignerSerializationVisibilityAttribute attribute to achieve that functionality
