实现代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using DevExpress.XtraBars.Alerter;

namespace DXApplication_1
{
    public partial class AlertControlForm : DevExpress.XtraEditors.XtraForm
    {
        public AlertControlForm()
        {
            InitializeComponent();
        }

        private void AlertControlForm_Load(object sender, EventArgs e)
        {
            // Create a regular custom button.
            AlertButton btn1 = new AlertButton(Image.FromFile(@"C:\\Users\\teeking_scx\\source\\repos\\DXApplication_1\\imgs\\new.png"));
            btn1.Hint = "Open file";
            btn1.Name = "buttonOpen";

            // Create a check custom button.
            AlertButton btn2 = new AlertButton(Image.FromFile(@"C:\\Users\\teeking_scx\\source\\repos\\DXApplication_1\\imgs\\heart.png"));
            btn2.Style = AlertButtonStyle.CheckButton;
            btn2.Down = true;
            btn2.Hint = "Alert On";
            btn2.Name = "buttonAlert";

            // Add buttons to the AlertControl and subscribe to the events to process button clicks
            alertControl1.Buttons.Add(btn1);
            alertControl1.Buttons.Add(btn2);

            alertControl1.ButtonClick += new AlertButtonClickEventHandler(alertControl1_ButtonClick);
            alertControl1.ButtonDownChanged +=
            new AlertButtonDownChangedEventHandler(alertControl1_ButtonDownChanged);

            // Show a sample alert window.
            AlertInfo info = new AlertInfo("New Window", "Text");
            alertControl1.Show(this, info);    
        }


        void alertControl1_ButtonDownChanged(object sender,AlertButtonDownChangedEventArgs e)
        {
            if (e.ButtonName == "buttonOpen")
            {
            }

        }

        void alertControl1_ButtonClick(object sender, AlertButtonClickEventArgs e)
        {
            if (e.ButtonName == "buttonAlert")
            {
            }
        }

    }
}
