从C＃WinForms应用程序禁用打开超链接的浏览器

Question

We have a .Net application that embeds google maps in some of the pages. We would like to prevent the user from opening a WebBrowser control when they click on a link found in Google Maps (such as in info tips on places etc...). Is this possible? I'm fairly new to .Net :)

Answer 1

尝试使用WebBrowser.AllowNavigation禁用导航

Answer 2

You can prevent navigations that are based on clicking a link using these 2 ways:

1- Using AllowNavigation property

this.webBrowser1.AllowNavigation = false;

2- Using Navigating event

private void BrowserSample_Load(object sender, EventArgs e)
{
    this.webBrowser1.Navigate("http://www.google.com");
    this.webBrowser1.Navigating += webBrowser1_Navigating;
}

private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    //you can use e.Url to allow or deny navigation based on your logic
    e.Cancel = true;
}

Consider these notes when using one of the ways above:

• Using Navigating event you can gain more control over navigation and you can prevent some navigations and allow some others.
• When using Navigating event, remember to add handler of this event only after you navigated to your desired url.
• Using these ways, you can only prevent navigations that are based on clicking a link, for example if you set the initial url too google, then you can perform search but you can't navigate to urls or results.
