ToolTip with Images

The Tooltips that comes out of the box for winforms do not support images on them. This is a simple class that allows you to add Images and Text to your ToolTips

using System;

using System.Windows.Forms;

using System.Collections.Generic;

using System.Text;

using System.Drawing;

namespace CustomControls

class ToolTipWithImage : Control

private Image _img;

private Control _ctl;

private Timer _timer;

string _imgfilename;

string _tiptext;

public String TipText

get { return _tiptext; }

set { _tiptext = value; }

public String ImageFile

get

return _imgfilename;

set

if (_imgfilename == value)

else

_imgfilename = value;

try

_img = Image.FromFile(_imgfilename);

this.Size = new Size(_img.Width + 70, _img.Height);

catch

_img = null;

public ToolTipWithImage()

this.Location = new Point(0, 0);

this.Visible = false;

_timer = new Timer();

_timer.Tick += new EventHandler(ShowTipOff);

public void SetToolTip(Control ctl)

ctl.Parent.Controls.Add(this);

ctl.Parent.Controls.SetChildIndex(this, 0);

ctl.MouseMove += new MouseEventHandler(ShowTipOn);

protected override void OnPaint(PaintEventArgs e)

if (_img != null)

e.Graphics.DrawString(TipText, this.Font, Brushes.Black, _img.Width, 0);

public void ShowTipOn(object sender, MouseEventArgs e)

if (!this.Visible)

this.Left = _ctl.Left + e.X + 100;

this.Top = _ctl.Top + e.Y;

this.Visible = true;

public void ShowTipOff(Object sender, EventArgs e)

this.Visible = false;

To use it just do something like

ToolTipWithImage timg = new ToolTipWithImage();

timg.TipText = "Hello";

timg.ImageFile = @"C:\Hello.gif";
