ToolTip

Synopsis

The ToolTip component can provide pop-up tips: the little yellow boxes that offer pithy assistance to the user if they hover their mouse over a Control. It implements System.ComponentModel.IExtenderProvider to provide a ToolTip extender property for Control objects on the design surface.

Programatically, you can use GetToolTip() and SetToolTip() to specify the tip text for a specific Control, and enable or disable the tips with the Active property. You can clear the tips with the RemoveAll() method.

The AutoPopDelay is the amount of time for which the tip will show before it disappears.

The InitialDelay is the period for which the user has to hover the mouse before the tip will appear.

The ReshowDelay is the amount of time that must elapse between the user moving the cursor over another control and the tool tip updating with the new tip text.

Instead of setting all these individual elements, you can set the AutomaticDelay property. This sets each property to a sensible number, based on the value you provide.
