How can I resize the text inside the WebBrowser control

Question

Hi, when using IE you can hold the Ctrl button and use the mouse wheel to resize.

But this does not work when using a Silverlight Out-Of-Browser WebBrowser control,
is there any way to get around this.

By the way, I could not find the Silverlight link on the page, so I chose WPF group.

Answer 1

I have not tested this code but give it a try:

public static partial class WBExtensions 
{ 
    public static void SetZoom(this System.Windows.Controls.WebBrowser WebBrowser1, double Zoom) 
    { 
        // For this code to work: add the Microsoft.mshtml .NET reference       
        mshtml.IHTMLDocument2 doc = WebBrowser1.Document as mshtml.IHTMLDocument2; 
        doc.parentWindow.execScript("document.body.style.zoom=" + Zoom.ToString().Replace(",", ".") + ";"); 
    } 
} 

So you would have to capture the CTL wheel gesture, and call this extension method.

There is no .Document in the Silverlight WebBrowser.

I was hoping there was a property somewhere I could turn on, maybe in the registry.

I will use JavaScript and call it from the out of browser application.

Oh yes I forgot, welcome to the Misery of Silverlight.  In their wisdom they decided not to give access in Silverlight to the DOM.  That may have changed a bit with 5.0..  But get this, you CAN access it in Javascript on same page.  You are better off posting this over in Silverlight forums.
