How to disable right click context menu

[richmondwang]

Hey, how can I disable the right click context menu on the web view.

I need not to show the source code of my html... thanks

I have the opposite requirement, how can I add and enable the items on the existing menu?
And furthermore, I would like to implement an enhanced editor for source code.

Thanks in advance.

@richmondwang if you are in control of the HTML being loaded (i.e. you're loading it in manually or restricting the WebView to only navigate to a certain set of pages) then just add this to the body tag of your page(s):

oncontextmenu="return false"

See https://github.com/intninety/yaircc/blob/master/yaircc/UI/default.htm if you need an example.

thanks @intninety ! I'll try it, hope it works.. 👯

You're welcome! :) As long as JavaScript isn't disabled in your WebView it should be fine.

you can return false from an IMenuHandler.OnBeforeMenu() to disable the context menu. I don't think CEF has support for adding custom items to the context menu at this time.

I also need to disable context menu in our application. But returning false from IMenuHandler.OnBeforeMenu doesn't prevent the context menu to appear.

I modified CefSharp.WinForms.WebView to include a new property:

    public virtual IMenuHandler MenuHandler
    {
        get { return browserCore.MenuHandler; }
        set { browserCore.MenuHandler = value; }
    }

then use this to include a custom MenuHandler. The MenuHandler OnBeforeMenu nevers gets called.

When digging in BrowserCore, I see that MenuHandler and its underlying variable are not connected to anything. Could you maybe point me to the right direction to fix this?

Thanks!

In 1.25.0, you should return true from an IMenuHandler.OnBeforeMenu() to disable the context menu.

I am using the latest code from CefSharp3 branch.

I tested it in 1.25 and it works, but I am using cefsharp3 to be future proof.

This method is empty: ClientAdapter::OnBeforeContextMenu
