Hello Nat,

Thank you for writing.

You can achieve your requirement using custom PropertyGridItemElement with custom PropertyGridValueElement. Here is a sample implementation:

public Form1()

{

    InitializeComponent();

     

    this.radPropertyGrid1.PropertyGridElement.PropertyTableElement.ItemHeight = 37;

 

    this.radPropertyGrid1.CreateItemElement += radPropertyGrid1_CreateItemElement;

    this.radPropertyGrid1.Editing += radPropertyGrid1_Editing;

    this.radPropertyGrid1.SelectedObject = new Item(123, "Title", DeliveryType.PickUp);

}

 

private void radPropertyGrid1_Editing(object sender,

    PropertyGridItemEditingEventArgs e)

{

    if (e.Item.Name == "DeliveryType")

    {

        e.Cancel = true;

    }

}

 

private void radPropertyGrid1_CreateItemElement(object sender,

    CreatePropertyGridItemElementEventArgs e)

{

    if (e.Item.Name == "DeliveryType")

    {

        e.ItemElementType = typeof(CustomItemElement);

    }

}

 

public class CustomItemElement : PropertyGridItemElement

{

    protected override PropertyGridValueElement CreatePropertyGridValueElement()

    {

        return new CustomPropertyGridValueElement();

    }

 

    protected override Type ThemeEffectiveType

    {

        get

        {

            return typeof(PropertyGridItemElement);

        }

    }

}

 

public class CustomPropertyGridValueElement : PropertyGridValueElement

{

    StackLayoutElement stackPanel;

 

    protected override void CreateChildElements()

    {

        base.CreateChildElements();

 

        stackPanel = new StackLayoutElement();

        stackPanel.Orientation = Orientation.Vertical;

        foreach (var enumItem in Enum.GetValues(typeof(DeliveryType)))

        {

            RadRadioButtonElement rb = new RadRadioButtonElement();

            rb.Text = enumItem.ToString();

            rb.ToggleStateChanged += rb_ToggleStateChanged;

            stackPanel.Children.Add(rb);

        }

        this.Children.Add(stackPanel);

    }

 

    private void rb_ToggleStateChanged(object sender, StateChangedEventArgs args)

    {

        RadRadioButtonElement rb = sender as RadRadioButtonElement;

        PropertyGridItem item = this.VisualItem.Data as PropertyGridItem;

        if (item != null && rb.Text != item.FormattedValue && rb.ToggleState == ToggleState.On)

        {

            item.Value = rb.Text;

        }

    }

     

    public override void Synchronize()

    {

        PropertyGridItem item = this.VisualItem.Data as PropertyGridItem;

        foreach (RadRadioButtonElement rb in stackPanel.Children)

        {

            if (rb.Text == item.FormattedValue)

            {

                rb.ToggleState = ToggleState.On;
                       break;

            }

        }

    }

}

 

public class Item

{

    public int Id { get; set; }

 

    public string Title { get; set; }

 

    public DeliveryType DeliveryType { get; set; }

 

    public Item(int id, string title, DeliveryType deliveryType)

    {

        this.Id = id;

        this.Title = title;

        this.DeliveryType = deliveryType;

    }

}

 

public enum DeliveryType

{

    Delivery,

    PickUp,

}

I hope this information helps. Should you have further questions, I would be glad to help.
