Public ReadOnly Property WindowFrameElement As HtmlElement

Property Value

HtmlElement

An HtmlElement corresponding to this window's FRAME element. If this window is not a frame, it returns null.

Examples

The following code example compares the SRC attribute of frames in a FRAMESET to the current location. If they are different, the frames are reset to their original URLs.

private void ResetFrames()
{
    if (!(webBrowser1.Document == null)) 
    {
        HtmlElement frameElement = null;
        HtmlWindow docWindow = webBrowser1.Document.Window;

        foreach (HtmlWindow frameWindow in docWindow.Frames)
        {
            frameElement = frameWindow.WindowFrameElement;
            String originalUrl = frameElement.GetAttribute("SRC");

            if (!originalUrl.Equals(frameWindow.Url.ToString())) 
            {
                frameWindow.Navigate(new Uri(originalUrl));
            }
        }
    }
}

Private Sub ResetFrames()
    If (WebBrowser1.Document IsNot Nothing) Then
        Dim FrameElement As HtmlElement
        Dim DocWindow As HtmlWindow = WebBrowser1.Document.Window

        For Each FrameWindow As HtmlWindow In DocWindow.Frames
            FrameElement = FrameWindow.WindowFrameElement
            Dim OriginalUrl As String = FrameElement.GetAttribute("SRC")

            If (Not OriginalUrl.Equals(FrameWindow.Url.ToString())) Then
                FrameWindow.Navigate(New Uri(OriginalUrl))
            End If
        Next
    End If
End Sub

Remarks

When you retrieve a FRAME element from the Frames collection, it returns an HtmlWindow. Call WindowFrameElement on this object if you need to access attributes of the underlying FRAME element, such as the SRC attribute.
