单击任何想法时，自定义 C# 按钮什么也不做？

Question

I have just made a new button for my C# uni project. For some reason it doesn't seem to work any ideas?

Here is my code for the button:

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

namespace CSD_A2_WS2435593_WS243380.Classes.FormsaAndControls
{
    class clsFlatButton : Button //control object declaration.
    {
        public clsFlatButton()
        {
            BackColor = Color.FromArgb(225, 236, 244);
            ForeColor = Color.FromArgb(57, 115, 157);
        }

        protected override void OnPaint (PaintEventArgs e) //draws the rectangle and text
        {
            e.Graphics.FillRectangle(new SolidBrush(BackColor), 0, 0, this.Width, this.Height);
            TextFormatFlags flags = TextFormatFlags.HorizontalCenter | TextFormatFlags.VerticalCenter;
            TextRenderer.DrawText(e.Graphics, Text, Font, new Point(Width + 3, Height / 2), ForeColor, flags);
        }

        protected override void OnMouseEnter(EventArgs e) //changes on mouse hover it enters the box
        {
            base.OnMouseEnter(e);
            BackColor = onMouseHoverBackColour;
            ForeColor = onMouseHoverForeColour;
        }
        protected override void OnMouseLeave(EventArgs e) //changes on mouse hover when it leaves the box
        {
            base.OnMouseEnter(e);
            BackColor = Color.FromArgb(225, 236, 244);
            ForeColor = Color.FromArgb(57, 115, 157);
        }
        protected override void OnMouseDown(MouseEventArgs e) //changes on mouse click
        {
            base.OnMouseDown(e);
            BackColor = Color.FromArgb(57, 115, 157);
            ForeColor = Color.FromArgb(225, 236, 244);
        }
        protected override void OnMouseUp(MouseEventArgs e)
        {
            base.OnMouseDown(e);
            BackColor = Color.FromArgb(225, 236, 244);
            ForeColor = Color.FromArgb(57, 115, 157);
        }
        //Available settings:
        //Static values for initialisation.
        private Color onMouseHoverBackColour = Color.FromArgb(251, 255, 255);
        private Color onMouseHoverForeColour = Color.FromArgb(6, 64, 106);
        //These will appear on the clsFlatButton control so they can be changed.
        public Color onMouseHoverBackColourChanger
        {
            get { return onMouseHoverBackColour;}
            set { onMouseHoverBackColour = value; }
        }
        public Color onMouseHoverForeColourChanger
        {
            get { return onMouseHoverForeColour; }
            set { onMouseHoverForeColour = value; }
        }
    }
}

So when I go to click it it does change colour even when hover, though it does not actually execute the code inside of it.

So I have nothing else to say but stackoverflow won't let me post this question without more normal text. So here we go I guess, I could just paste lorem ipsum but I don't want to be shouted at.

This happens because you are invoking

base.OnMouseDown and not base.OnMouseUp in

protected override void OnMouseUp(MouseEventArgs e)

I've reproduced the problem, and fixed it by:

    protected override void OnMouseUp(MouseEventArgs e)
    {
        base.OnMouseUp(e);
        BackColor = Color.FromArgb(225, 236, 244);
        ForeColor = Color.FromArgb(57, 115, 157);
    }
