MouseEventArgs.Y Property

Gets the y-coordinate of the mouse during the generating mouse event.

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

public int Y { get; }

Property Value

Type: System.Int32
The y-coordinate of the mouse, in pixels.

The mouse coordinates vary based on the event being raised. For example, when the Control.MouseMove event is handled, the mouse coordinate values are relative to the coordinates of the control that raised the event. Some events related to drag-and-drop operations have associated mouse coordinate values that are relative to the form origin or the screen origin.

The following code example uses the X and Y properties to display the current position of the mouse pointer in a ToolTip window. To use this code, call TrackCoordinates from the form constructor.


ToolTip trackTip;

private void TrackCoordinates()
{
    trackTip = new ToolTip();
    this.MouseMove += new MouseEventHandler(Form1_MouseMove);
}

void Form1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
    String tipText = String.Format("({0}, {1})", e.X, e.Y);
    trackTip.Show(tipText, this, e.Location);
}
