Wpf Webbrowser Mouse Events Not Working as Expected

WPF WebBrowser Mouse Events not working as expected

Mouse events are not supported by the WebBrowser control, according to the documentation. You need to hook up handlers to the DOM events provided by the document being displayed in the control, using the WebBrowser.Document property. This post has an example of how to do this.

WPF Browser control Mousedown event not firing

I got the solution by injecting javascript that adds a html mousedown event to the website. The javascirpt in turn invokes a wpf function that is written into a class using ComVisible[true].

WPF WebBrowser disabling mouse events for webpages in the browser?

The WebBrowser control is not a usual wpf control. Its an activeX host that hosts the browser inside a new window that is drawn on top of your wpf window. This is known as the windows 'Airspace issue'.

This is why setting the IsEnabled property or placing another control on top of it does not work.
Since the WebBrowser has its own window, the only way to prevent mouse input to your web page is to prevent mouse input to the browsers window. You can do this with an external call to EnableWindow(IntPtr hWnd, bool enable).

Here is a small sample:

MainWindow.xaml:

<Window x:Class="Test.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="MainWindow"
    Width="800"
    Height="450"
    mc:Ignorable="d">
    <Grid>
        <WebBrowser x:Name="Browser"/>
    </Grid>
</Window>

MainWindow.xaml.cs:

namespace Test
{
    static class Win32
    {
        [DllImport("user32.dll")]
        public static extern bool EnableWindow(IntPtr hWnd, bool enable);
    }

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            Loaded += MainWindow_Loaded;
        }

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            Win32.EnableWindow(Browser.Handle, false);
        }
    }
}

This will disable all mouse and keyboard inputs to the browser window.

WPF WebBrowser control - Navigating event not firing

Just to close this question: in my case it was some kind of problem at system level, IE was behaving strangely in other scenarios too. On a new Windows installation it started working again.

Mouse over events with path in a grid don't work as expected, wpf

As mentioned in the comment if you want whole Grid to be hit test visible you need to initialize Background property of the Grid with some brush, for example Transparent which will have same visual effect as null but will make whole Grid hit test visible.

<Grid ... x:Name="gdOpenBrowser" Background="Transparent">

ol3 with IE11 in a c# webbrowser control mouse click events not working

So, I decided to roll back to IE10. Everything works in both the native browser and in the WebBrowser control.

IE11 breaks too much stuff, and isn't worth the "upgrade" at this point in time.

I will be checking out CefSharp in the future, just not enough time to put into upcoming release.

Mouse-down event not working on Canvas control in my wpf application

This is simple enough, and actually has nothing to do with MVVM at all.

Look at the XAML definition, your TextBlock is taking up all available space of the 2nd column, the canvases are beneath it so they can not respond to the mouse clicks.

Set a decent size to the TextBlock and move it to one of the corners can solve your problem.

Or you can recorder the Z-Order of the controls, first the TextBlock, then the canvases.
