Gets or sets the position of the mouse cursor relative to a relatively positioned parent element.

public:
 property System::Drawing::Point MousePosition { System::Drawing::Point get(); };
public System.Drawing.Point MousePosition { get; }
member this.MousePosition : System.Drawing.Point
Public ReadOnly Property MousePosition As Point

Property Value

Point

The position of the mouse cursor relative to the upper-left corner of the parent of the element that raised the event, if the parent element is relatively positioned.

Examples

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

<HTML>  

<BODY>  

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

</BODY>  

</HTML>

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;
    MessageBox.Show(msg);
}

Private Sub HtmlDocument_Click(ByVal sender As Object, ByVal e As HtmlElementEventArgs)
    Dim doc As HtmlDocument = webBrowser1.Document
    Dim msg As String = "ClientMousePosition: " & e.ClientMousePosition.ToString() & vbCrLf & _
        "MousePosition: " & e.MousePosition.ToString() & vbCrLf & _
        "OffsetMousePosition: " & e.OffsetMousePosition.ToString()
    MessageBox.Show(msg)
End Sub

Remarks

Relative positioning is used in HTML to place an element on a page in relation to its parent.

If an element is relatively positioned, this property will return the same result as ClientMousePosition.
