HtmlElementEventArgs.OffsetMousePosition Property

Gets or sets the position of the mouse cursor relative to the element that raises the event.

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

public Point OffsetMousePosition { get; }

Property Value

Type: System.Drawing.Point
The mouse position relative to the element that raises the event.

The following HTML file demonstrates relative positioning of a TABLE inside of a BODY tag.



    <TABLE style="position:relative;top:100px;left:100px;">
            <TD>More text</TD>



The following code example displays the difference between MousePosition, ClientMousePosition and OffsetMousePosition when the user clicks on an element of the TABLE. ClientMousePosition will display coordinates relative to the upper-left corner of the document's client area. MousePosition will display coordinates relative to the upper-left corner of the TABLE. If you click on one of the lines of text, OffsetMousePosition will display coordinates relative to that TD element.

This example requires that you have configured Document_MouseDown as a handler for the MouseDown event on HtmlDocument.

void Document_Click(object sender, HtmlElementEventArgs e)
    HtmlDocument doc = webBrowser1.Document;
    string msg = "ClientMousePosition: " + e.ClientMousePosition.ToString() + "\n" +
        "MousePosition: " + e.MousePosition + "\n" +
        "OffsetMousePosition: " + e.OffsetMousePosition;
