Question

I would like to display a ToolTip for when the mouse is hovering over a control.

How does one create a tooltip in code, but also in the designer?

Answer 1

Here is your article for doing it with code

private void Form1_Load(object sender, System.EventArgs e)
{
     // Create the ToolTip and associate with the Form container.
     ToolTip toolTip1 = new ToolTip();

     // Set up the delays for the ToolTip.
     toolTip1.AutoPopDelay = 5000;
     toolTip1.InitialDelay = 1000;
     toolTip1.ReshowDelay = 500;
     // Force the ToolTip text to be displayed whether or not the form is active.
     toolTip1.ShowAlways = true;

     // Set up the ToolTip text for the Button and Checkbox.
     toolTip1.SetToolTip(this.button1, "My button1");
     toolTip1.SetToolTip(this.checkBox1, "My checkBox1");
}
