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")
			{
			}
		}

	}
}
