I'm using the code from the following link: Displaying html from string in WPF WebBrowser control
It works well except when I delete the item containing the html, e.NewValue
becomes null
and I get an exception. Is there a way to return the WebBrowser control to a blank screen?
I found this. Anyone have anything better?
if (wb != null)
{
if (e.NewValue != null)
wb.NavigateToString(e.NewValue as string);
else
wb.Navigate("about:blank");
}
我只是将WebBrowserLabel的DocumentText设置为string.Empty 。
