Clearing the selection in a webbrowser control

问题

I have a form with webbrowser control ,where i am coping all the TEXT(not html) data to clipboard

For this the code snippet is :-

webBrowser2.Document.ExecCommand("SelectAll", false, null);
webBrowser2.Document.ExecCommand("Copy", false, null);

I have written the above code under webBrowser2_DocumentCompleted .

The problem is that the webpage in webbrowserControl appears with selection. I want to clear that selection after copy operation.

Is there a way to do this or a command such as

 webBrowser2.Document.ExecCommand("ClearSelection", false, null);  //This doesn't work

回答1:

If you import the Microsoft.mshtml library (C:\Program Files\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll), you can use the selection property of the web-browser's Document:

using mshtml;

...

IHTMLDocument2 htmlDocument = webBrowser2.Document.DomDocument as IHTMLDocument2;

IHTMLSelectionObject selection = htmlDocument.selection;

if (selection != null) {
    selection.clear();
}

Otherwise, you could always Navigate to a script URI:

webBrowser2.Navigate("javascript:document.selection&&document.selection.clear();");

Edit: Changed it to use Navigate, instead of InvokeScript.

I was able to use the Refresh method of the browser control to do the same thing. (i.e. webBrowser2.Refresh())

回答3:

If you want to unselect the selection then use:

htmlDocument.ExecCommand("Unselect", false, Type.Missing);

But if you want to remove (hide) a word selected:

IHTMLDocument2 htmlDocument = webBrowser2.Document.DomDocument as IHTMLDocument2;
IHTMLSelectionObject selection = htmlDocument.selection;

if (selection != null) {
    selection.clear();
}
