MouseEventArgs.Location Property

Definition

Gets the location of the mouse during the generating mouse event.

public System.Drawing.Point Location { get; }

Property Value

A Point that contains the x- and y- mouse coordinates, in pixels, relative to the upper-left corner of the control.

Examples

The following code example uses the Location property to track left mouse clicks and draw a series of straight line segments in response to user input. The example does not persist the drawn lines if you hide the form and then redisplay it; this code was omitted for simplicity.

Point firstPoint;
Boolean haveFirstPoint;

public void EnableDrawing()
{
    this.MouseDown += new MouseEventHandler(Form1_MouseDownDrawing);
}

void Form1_MouseDownDrawing(object sender, System.Windows.Forms.MouseEventArgs e)
{
    if (haveFirstPoint)
    {
        Graphics g = this.CreateGraphics();
        g.DrawLine(Pens.Black, firstPoint, e.Location);
        haveFirstPoint = false;
    }
    else
    {
        firstPoint = e.Location;
        haveFirstPoint = true;
    }
}
