Please let me know , how to add tooltip for a disabled button

Answer 1

Please refer to the following code to enable tooltip for the disabled button:

 bool IsShown = false;  
        private void Form1_Load(object sender, System.EventArgs e)  
        {  
            toolTip1.AutoPopDelay = 5000;  
            toolTip1.InitialDelay = 1000;  
            toolTip1.ReshowDelay = 500;  
  
            toolTip1.ShowAlways = true;  
  
            toolTip1.SetToolTip(this.button1, "test button");  
        }  
  
  
        void Form1_MouseMove(object sender, MouseEventArgs e)  
        {  
            Control ctrl = this.GetChildAtPoint(e.Location);  
  
            if (ctrl != null)  
            {  
                if (ctrl == this.button1 && !IsShown)  
                {  
                    string tipstring = this.toolTip1.GetToolTip(this.button1);  
                    this.toolTip1.Show(tipstring, this.button1, this.button1.Width / 2, this.button1.Height / 2);  
                    IsShown = true;  
                }  
            }  
            else  
            {  
                this.toolTip1.Hide(this.button1);  
                IsShown = false;  
            }  
        }  
        private void button1_Click(object sender, EventArgs e)  
        {  
            button1.Enabled = false;  
        }  

I haven't found a way to do it without any Mouse events. It seems that Mouse_Move is necessary.

If it were in WPF, it would be simpler.

<Button x:Name="button" ToolTipService.ShowOnDisabled="True" Content="Button"/>
