Having a WebBrowser control, I roughly do the following steps:
- Navigate to "
about:blank". - Turn on design mode in
DocumentCompletedevent handler. - Paste a HTML string with an
#as the URL. - Read the document back from the WebBrowser control.
Step 2 is done by this way:
private void webBrowser1_DocumentCompleted(
object sender,
WebBrowserDocumentCompletedEventArgs e)
{
dynamic axObj = webBrowser1.ActiveXInstance;
axObj.document.designmode = "On";
}
Step 3 is done this way:
private void button1_Click(object sender, EventArgs e)
{
var doc = (HTMLDocument)webBrowser1.Document.DomDocument;
var selection = doc.selection;
var range = (IHTMLTxtRange)selection.createRange();
range.pasteHTML("<p><a href=\"#\">Read more</a></p>");
}
Step 4 is done this way:
private void button2_Click(object sender, EventArgs e)
{
MessageBox.Show(this, webBrowser1.DocumentText);
}
What I expect:
I would expect to get a HTML string like this:
<html><body>
<p><a href="#">Read more</a></p>
</body></html>
What I actually get:
I get an HTML string where the # URL is prefixed with the current document's URL:
<html><body>
<p><a href="about:blank#">Read more</a></p>
</body></html>
This happens, no matter whether I navigate to about:blank or e.g. https://www.google.com or any other URL.
My question:
Is there any way to prevent IE/mshtml/WebBrowser control from prefixing the currently loaded URL when pasting anchors?
Update 1:
A possible workaround I can think of is to paste an absolute URL like e.g. http://pseudo-hash.com instead of the # and later when getting the HTML back from the WebBrowser control do a string replace and replace the pseudo placeholder URL back with #.
