ToolTip.Show Method (String, IWin32Window, Point)

Sets the ToolTip text associated with the specified control, and then displays the ToolTip modally at the specified relative position.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public void Show(
	string text,
	IWin32Window window,
	Point point
)

Parameters

text
Type: System.String

A String containing the new ToolTip text.

window
Type: System.Windows.Forms.IWin32Window

The Control to display the ToolTip for.

point
Type: System.Drawing.Point

A Point containing the offset, in pixels, relative to the upper-left corner of the associated control window, to display the ToolTip.

ExceptionCondition
ArgumentNullException

The window parameter is null.

The pt parameter can specify a position outside the bounds of the associated control, its parent form, or even the desktop. The version of the Show method displays the ToolTip for the specified control modally; that is, the ToolTip will be displayed until the Hide method is called, or until the parent form is minimized, hidden, or dismissed.

Applications running in partial trust must assert the AllWindows permission to use this method, as Show can control the display and location of a ToolTip independent of user action.
