无法以编程方式添加自定义控件

Question

I have created a custom control and want to be able to add it at run time but it is not working. I can add it through design view and it works fine. My code is below for the custom control and where I am adding it.

PluginControlButton.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace customControlLib
{
    public partial class PluginControlButton : Control
    {
        private Color color1 = Color.LightGray;
        private Color color2 = Color.Black;
        private Color color3 = Color.White;
        private Color colorU = Color.Yellow;
        private int cpSize = 70;
        private Image backgroundImage;
        /// <summary>
        /// The image for the plugin
        /// </summary>
        [Category("PluginControlSettings")]
        public Image PluginImage
        {
            get { return backgroundImage; }
            set { backgroundImage = value; Invalidate(); }
        }
        /// <summary>

        /// </summary>
        [Category("PluginControlSettings")]
        public int ComponentSize
        {
            get { return cpSize; }
            set
            {

                    return;
                cpSize = value;
                cpSize = value;

                Invalidate();

Ok, it is working now, I had to add a size to the component. Thanks for the help.

customControlLib.PluginControlButton pbc = new customControlLib.PluginControlButton()
        {
            ComponentSize = 70,
            InnerColor = Color.Black,
            Name = "TEST",
            PluginImage = null,
            ProcessColor = System.Drawing.Color.LightGray,
            Size = new System.Drawing.Size(70, 70),
            Text = "Test",
            textColor = System.Drawing.Color.White,
            UpdateColor = System.Drawing.Color.Yellow
        };
