HtmlElement.ClientRectangle Property


Gets the bounds of the client area of the element in the HTML document.

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

Property Value

The client area occupied by the element, minus any area taken by borders and scroll bars. To obtain the position and dimensions of the element inclusive of its adornments, use OffsetRectangle instead.


Assume you have loaded the following HTML page into a hosted instance of the WebBrowser control.



        <DIV id="div1" style="position:absolute;top:100px;left:100px;border-      style:solid;border-width:1px;">  
            Edit this text.  



The following code example demonstrates retrieving this element and expanding its dimensions if the client area is less than 400 pixels wide by 50 pixels high, and also sets the DIV to the contentEditable state so that the user can input text.

private void EnableEditing()
    if (webBrowser1.Document != null)
        HtmlElement elem = webBrowser1.Document.GetElementById("div1");
        if (elem != null)
            if (elem.ClientRectangle.Width < 200)
                elem.SetAttribute("width", "200px");

            if (elem.ClientRectangle.Height < 50)
                elem.SetAttribute("height", "50px");

            elem.SetAttribute("contentEditable", "true");
Private Sub EnableEditing()
    Dim Elem As HtmlElement = WebBrowser1.Document.GetElementById("div1")
    If (Not Elem Is Nothing) Then
        If (Elem.ClientRectangle.Width < 200) Then
            Elem.SetAttribute("width", "200px")
        End If

        If (Elem.ClientRectangle.Height < 50) Then
            Elem.SetAttribute("height", "50px")
        End If

        Elem.SetAttribute("contentEditable", "true")
    End If
End Sub


ClientRectangle will return position data only for elements that have been assigned an explicit height and width, or elements that use absolute positioning. A document is absolutely positioned if its position style is set to absolute, after which it can be positioned at any coordinate on the HTML page.
