We have to add a web browser control in design page and please make it hidden by default as we are going to use it internally so the end user cannot see this control.<\/p>\n
Please refer the below mentioned code for adding \u201cWebBrowserControl\u201d in design or \u201c.xaml\u201d page.<\/p>\n
[code lang=”c”]<\/p>\n
\/\/ adding WebBrowser control in design page
\n<WebBrowser x:Name=”WebBrowserControlCreatePage” Grid.Row=”0″ Grid.Column=”0″ Height=”10″ Width=”10″ Visibility=”Hidden”\/>;<\/p>\n
