Xamarin Forms: WebView in a ScrollView - Can't scroll webview content because scrollview grabs the gesture

[vsfeedback]

VSF_TYPE_MARKDOWN```XML <ScrollView x:Name="masterScroll" HorizontalOptions="StartAndExpand" VerticalOptions="StartAndExpand" BackgroundColor="Fuchsia"> <!--#region Limited web browser with authentication--> <controls:AuthWebView x:Name="Browser" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" HeightRequest="750" BackgroundColor="SaddleBrown" Navigated="Browser_NavigationDone" Navigating="Browser_NavigationStarting" Password="admin" ShouldTrustUnknownCertificate="True" Source="{Binding BrowserAddy}" Username="admin" /> </ScrollView> ``

So... If you navigate to a page that has some scrolling content... Anything with a scroll control such as this very page with a scrolling text editor... You can't scroll the scrollable content in the WebView because the encasing ScrollView grabs all the tap guesture, no matter where you touch.

I would expect, that if you are trying to scroll over a scrollable area then the gesture falls through. If you try to scroll and the control below is not capable of taking the gesture, then the parent gesture uses it. IE: Try to scroll over a Text box or list of some type should scroll the webview content. Try to scroll anywhere else on the page, and it should move the ScrollView

Does that make sense?

This would probably be resolved by #2680

[jrahma]

Same problem here

A webView in a scrollView seems to work on iOS but not on Android.

[tyagishubham177]

#2680 is resolved but the issue is still there. I have tried with following code on android but no luck Control.RequestDisallowInterceptTouchEvent(true); Control.NestedScrollingEnabled = true;

[jrahma]

Not working on Android

[pmahend1]

Yes. It does not work . Is there any work around?

<ScrollView>
    <WebView>
        <WebView.Source>
            <HtmlWebViewSource Html="{Binding MyHTMLText}" />
        </WebView.Source>
    </WebView>
</ScrollView>

[jrahma]

Still no luck!

[inshalirshad]

Still this issue is present.... Only a work around is for android but for IOS stills same. Expecting a fix from Xamarin. As this issue is been there from years now !

[SergTomcat]

Any progress on that issue?

[pooran]

Any resolution for this?

After 4 long years still no update? This bug is still present in Maui.

If we don't set the webview in a scrollview, the fields inside the webview are hidden by the softkeyboard. If we set the webview inside a scrollview, we are not able to scroll the webview.
