How to simulate a "open link on new window" on a C# WebBrowser?
I just found out that to simulate a click I can call element.InvokeMember("click");
where element
is an HtmlElement
. But what I actually need is to open the link in a new window, but not on the default br开发者_运维技巧owser but on another WebBrowser
I would create in my program. Sometimes it works to just get the href attribute by calling element.GetAttribute("href");
and then just navigating to the returned URL, but some picky web pages won't work this way, I assume something to do with cookies and sessions.
Just handle the NewWindow2 event, create a form/tab that has a webbrowser on it, and use the webbrowser as the target of the new window request. Check http://www.codeproject.com/KB/cpp/ExtendedWebBrowser.aspx for an example.
System.Windows.Forms.WebBrowser
is a very crippled control and one of its biggest problem - supporting of multi-tabbing. It doesn't support it at all.
I spent tons of time to try make it work properly but got no sufficient success, so recommend you to try 3rd party control instead.
Workaround: subscribe to click event of each <a>
on page (or some of them you need) and create a new windows manually. For example, see how does it implemented in dotBrowser: 1 2
foreach (HtmlElement tag in webBrowser.Document.All)
{
tag.Id = String.Empty;
switch (tag.TagName.ToUpper())
{
case "A":
{
tag.MouseUp += new HtmlElementEventHandler(link_MouseUp);
break;
}
}
}
private void link_MouseUp(object sender, HtmlElementEventArgs e)
{
mshtml.HTMLAnchorElementClass a = (mshtml.HTMLAnchorElementClass)((HtmlElement)sender).DomElement;
switch (e.MouseButtonsPressed)
{
case MouseButtons.Left:
{
// open new tab
break;
}
case MouseButtons.Right:
{
// open context menu
break;
}
}
}
