Context Menu in WebView2 PDF Viewer when selecting text

[VijayanRamachandran]

UseCase:

In an sample WPF window application i hosted a single instance of WebView2 as below ( In MainWindow.xaml ) and passed source url to load a sample PDF.
In addition to that I added a settings to CoreWebView2 to disable default context menu as below ( In MainWindow.xaml.cs )

MainWindow.xaml

MainWindow.xaml.cs

Current Behavior:

Upon RMB click on selected text we could see context menu as shown in below screenshot.

Is this expected behavior ?

Version Information

Nuget - Microsoft.Web.WebView2 => 1.0.818.41
Fixed Version: Microsoft.WebView2.FixedVersionRuntime.91.0.864.37.x64

Hey @VijayanRamachandran - thanks for the report. The settings typically require a navigation to take effect. If you reload the page or try navigating somewhere else first, do you still see this behavior?

@champnic
Yes i still see the same behavior even after settings takes effect.

Ex:

I tried as below in MainWindow.xaml.cs ( in addition to instead of setting Source in MainWindow.xaml to pdf )

    async void InitializeAsync()
    {
        await webView.EnsureCoreWebView2Async(null);

        webView.CoreWebView2.Settings.AreDefaultScriptDialogsEnabled = false;
        webView.CoreWebView2.Settings.IsWebMessageEnabled = false;
        webView.CoreWebView2.Settings.IsStatusBarEnabled = false;
        webView.CoreWebView2.Settings.AreDefaultContextMenusEnabled = false;
        webView.CoreWebView2.Settings.AreHostObjectsAllowed = false;
        webView.CoreWebView2.Settings.IsZoomControlEnabled = false;
        webView.CoreWebView2.Settings.IsBuiltInErrorPageEnabled = false;
        webView.CoreWebView2.Settings.AreDevToolsEnabled = false;
        webView.CoreWebView2.Settings.IsScriptEnabled = false;

        webView.CoreWebView2.Navigate(@"D:\WebView2-Preview-MS-PrivateMSI\12_WebView2Preview-Pdf\WebView2Preview\SamplePdf.pdf");
    }

I was able to repro the problem, and it looks like that menu shows up just by selecting text, not by using the right-mouse button. I don't think this is by design, so I've opened this bug on our backlog. Thanks!

This should be fixed in runtimes 99.0.1112.0+. Thanks!

Hello @champnic

I have the same issue on a touchpanel where a webview2 element is used to display a pdf. When selecting text with the touch control I get the same context menu as shown from @VijayanRamachandran. If I select text using my mouse I dont get the context menu.

MainWindow.xaml.cs
`using System.Windows;

namespace PDFViewer
{
///

/// Interaction logic for MainWindow.xaml
///

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
InitializeAsync();
}

    async void InitializeAsync()
    {
        await webView.EnsureCoreWebView2Async(null); // Initialize the control
        webView.CoreWebView2.Settings.AreDefaultContextMenusEnabled = false;
    }

}

}`

MainWindow.xaml
<Window x:Class="PDFViewer.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" xmlns:local="clr-namespace:PDFViewer" xmlns:wv2="clr-namespace:Microsoft.Web.WebView2.Wpf;assembly=Microsoft.Web.WebView2.Wpf" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> <Grid> <wv2:WebView2 Name="webView" Source="file:///D:/test.pdf#toolbar=0"/> </Grid> </Window>

Context menu that shows when selecting text with the touch control:

@sergimos This is a pretty old issue. Can you open a new one for the issue you are seeing?
