Question

I’m using a WPF WebBrowser control to preview HTML typed by the user.

example…

WPF TextBox and WebBrowser controls http://img411.imageshack.us/img411/2296/appbz9.jpg

But, how do I made the WebBrowser control read-only? I don’t want the user to be clicking links in there and navigating away from the preview page.

I want my users to create links. I just want to make sure the ‘preview’ pane is a preview of the correct page.

Answer 1

Capture the Navigating event of the WebBrowser control and set the Cancel property of its NavigatingCancelEventArgs to True.

Visual Basic code…

 Private Sub WebBrowser1_Navigating(...) Handles WebBrowser1.Navigating     If WebBrowser1Locked Then         e.Cancel = True     End If End Sub 

This requires a global locking boolean variable.

 Partial Public Class Window1     Dim WebBrowser1Locked As Boolean = True     ... End Class 

And locking and unlocking to be wrapped around the desired navigation.

 WebBrowser1Locked = False WebBrowser1.NavigateToString('...') WebBrowser1Locked = True
