WebBrowser in a StackPanel does not expand to its content size in WPF

I have to display multiple HTML contents on a single window. These data come as strings. Every string represents one HTML file data.
I am using webbrowser control and stackpanel layout to display them on a single window.
<Grid >
<ScrollViewer VerticalScrollBarVisibility="Auto">
<StackPanel Background="YellowGreen">
<WebBrowser Margin="5" Loaded="WebBrowser_Loaded"/>
<WebBrowser Margin="5" Loaded="WebBrowser_Loaded" />
<WebBrowser Margin="5" Loaded="WebBrowser_Loaded" />
</StackPanel>
</ScrollViewer>
private void WebBrowser_Loaded(object sender, RoutedEventArgs e)
{
WebBrowser web = sender as WebBrowser;
web.NavigateToString(VM.HtmlContent);
}
Problem: Webbrowser is not rendered to its content size.
Regardless of the actual content size, all webbrowsers take same amount of space in the stack panel.
Current Output Screenshot
Web browsers 2nd and 3rd have not taken the required amount of space to render the content.
It seems the Webbrowser control is not giving the right information about its content size to the stack panel.
Given that, web browsers get rendered to its content size, I would like to avoid the scroll bar at the web browser level.
Any help is highly appreciated. Thank you.

WebBrowser control does not support this functionality. However you can get the content size and resize controls manually as demonstrated in this thread: https://stackoverflow.com/a/40795036/12797700

Disable scrolling phone:webbrowser windows phone 8 / 8.1

I am trying to disable the scroll functionality in the phone:webbrowser in my windows phone 8 application. The reason i wan't to do this is that I want to place a stackpanel with items underneath the webview, but still show the whole webpage.
To accomplish this I get the total height of the webpage and set the height of the webbrowser to the webpage height. This will be done through adding javascript to the webbrowser. The webview will now have the total webpage and the items underneath it and both of those items are in a ScrollViewer so you can scroll through the page.
The only problem i have right now is that you can scroll the webbrowser so you cant scroll the scrollviewer. anyone got an idea how to fix this?
<ScrollViewer
Grid.Row="1"
Margin="0,0,0,0">
<StackPanel
x:Name="ContentPanel"
Margin="0,0,0,0">
<phone:WebBrowser
x:Name="webView"
Navigating="WebBrowserNavigating"
LoadCompleted="WebBrowserLoadCompleted"
ScriptNotify="browser_ScriptNotify"
IsScriptEnabled="True"/>
<StackPanel
x:Name="CouponHolder"
Margin="0,5,0,0">
</StackPanel>
</StackPanel>
</ScrollViewer>
I also looked at other questions, but they didnt work out for me:
http://www.codeproject.com/Tips/718671/Disable-WebView-scrolling-in-Windows-Store-Apps
And I see allot of people give awnsers like VerticalScrollBarVisibility="Disabled" but this doesnt work, like the suggests it will only hide the visibility...

you can disable all manipulation with WebBrowser control by setting IsHitTestVisible="false". The disadvantage is that you can't press Links, Navigate and so on.
If you want just to disable scrolling than take a look at this blog post:http://www.scottlogic.com/blog/2011/11/17/suppressing-zoom-and-scroll-interactions-in-the-windows-phone-7-browser-control.html
You can Find that the VisualTree of WebBrowser control looks like:
\-WebBrowser
\-Border
\-Border
\WebBrowserInteropCanvas (New in Windows Phone 8, missing in WP7)
\-PanZoomContainer
\-Grid
\-Border (you need access this one)
\-ContentPresenter
\-TileHost
You can get the last Border in VisualTree, and subscribe to ManipulationDelta, ManipulationStarted and ManipulationCompletedEvents. And set e.Handled = true; In event handlers. Be careful with that. For example where is no equialent for this code in Windows 8.1 and Windows Phone 8.1 (Runtime).
This hack will cancel scrolling of webbrowser while user can interract with entire web page, but you won't be able to suppress manipulation to put webbrowser in scrollviewer.
In general I don't think that you could achive ideal user experience if you put WebBrowser inside ScrollViewer

After hours of searching this project finally solved all our webview problems in Windows Phone 8.1 (bounce, touch, auto height etc.):

loading pic in xaml web browser.

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<phone:WebBrowser x:Name="browser" IsScriptEnabled="True" Margin="-12,0,-11,0" />
</Grid>
I initialized web browser using this code. Since, my html content is too big, it takes much more to load those html files. Till the html files displayed, web browser is being white color.
It makes me irritate. I need to know can we have any loader pic in web browser. So, the pic displayed until web browser loads the html files ???

I can't verify this at the moment but the approach I would take is to display an image via Image or some alternative, such as a loading message in XAML, and set the initial visibility of this stand-in to visible and the WebBrowser to collapsed.
Implement an event handler for the LoadCompleted event on the WebBrowser and when it is triggered, swap the visibility states to hide the progress/wait message and show the web browser.
It'll look roughly like:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<TextBlock Text="Loading... please wait" Visibility="Visibile" x:Name="loadingMessage"/>
<phone:WebBrowser x:Name="browser" IsScriptEnabled="True" Margin="-12,0,-11,0" LoadCompleted="htmlLoadCompleted" Visibility="Collapsed"/>
</Grid>
// In the code behind - HTML finished loading, swap visibility to show the page
private void htmlLoadCompleted(object sender, NavigationEventArgs e)
{
loadingMessage.Visibility = Visibility.Collapsed;
browser.Visibility = Visibility.Visibile;
}
I have concerns over when/how the WebBrowser starts loading, which is why I'd like to caution I don't have a local environment configured to verify this approach is 100% working. You might need to experiment with this some to get it working but I hope this helps set you on the right path.

How can I pop a control out of it's container to make it full screen when clicked in Silverlight/Wp7?

So I have a Panorama control and the PanoramaItems are programmatically added to the control using the following template.
<UserControl>
<Grid x:Name="LayoutRoot">
<controls:PanoramaItem Name="sitePanoramaItem" Header="{Binding Name}">
<Controls:DockPanel VerticalAlignment="Stretch">
<StackPanel Orientation="Horizontal" Margin="0,10,0,0" Controls:DockPanel.Dock="Top">
<Image Source="../Images/action.png" Width="64" />
<TextBlock Text="{Binding Stats, Mode=TwoWay}" FontSize="45" Margin="15,0,0,0" />
</StackPanel>
<Grid x:Name="graphCanvas" HorizontalAlignment="Stretch" Margin="10,10,10,10"> </Grid>
</Controls:DockPanel>
</controls:PanoramaItem>
</Grid>
</UserControl>
When I click on graphCanvas what I'd like to do is sorta pop the graphCanvas out and display that fullscreen then when I click again restore it to where it was. I've been all over this site and Google and can't find anything similar to what I'm looking for.
I would still like to maintain the Panorama control functionality so that the graphCanvas is still the only one visible but you can cycle through them. Currently I have it sorta working in that I remove the Grid from the DockPanel and put it directly in the LayoutRoot while making the sitePanoramaItem collapsed. However, it's not fullscreen as the Panorama name is still visible (I guess I could hide that as well...) When I put the graphCanvas back int he DockPanel the size of the canvas is all screwed up.
I was hoping there was a simpler way.
Is it even possible?

It is possible to create the UI you describe but it's not going to be simple. You're on the right track with removing it in code and adding it the LayoutRoot and making the Panorama hidden. However you would have to code the scrolling behavior yourself and that is going to be quite tricky - especially making it feel the way to panorama does.
One trick you could try is actually layer a PivotControl on top of your Panorama and have it be collapsed by default. Also edit it's template to remove all default content eg: remove the header control, set margins to 0, etc). Then when you want to go full screen you can remove all the graphCanvases from the Panorama items and and add them to new PivotItems in the PivotControl. Then hide the Panorama and show the Pivot. This will give you scrolling capability for free and the illusion of full screen.
Having said all that I'm not sure I would recommend this. The more common approach would be to simply be to navigate to another page when the user selects an item and handle the full screen aspects there (possibly using the Pivot control again for scrolling). And when you want to leave "fullscreen" mode simply navigate back to the first page. Handling Tombstoning of the fullscreen state will be much easier with this approach for one thing.

You can try making the graphCanvas a Page and putting it in a different XAML. Then add a frame (name it InnerFrame for example) in the same place where you have the graphCanvas right now and navigate to that page with InnerFrame. When the frame is clicked, you navigate with the RootFrame of the app to your graphCanvas page. When you decide to close it, just navigate back with the RootFrame.
Hope it's clear enough :)
Edit:
Navigation in WP7 works very similar as the standard navigation in Silverlight 4, but it's a bit more restrictive. Just throw a PhoneApplicationFrame in your XAML like this:
<phone:PhoneApplicationFrame x:Name="Frame" />
This is basically the same as a Silverlight frame. All the pages you create inherit from PhoneApplicationPage by default, so they can be showed in a frame without any changes.
Your whole application actually runs on a PhoneApplicationFrame. If you take a look at your App class you will see this:
public PhoneApplicationFrame RootFrame { get; private set; }
Here's the MSDN documentation for the navigation system on WP7

WP7 App: Too large page

I have created a small WP7 app which contains one page which is dynamically filled with content. But it goes out of viewable area. Emulator doesn't scroll the page when I click-hold-move on the screen. How do I make it scroll when needed?

One simple option is to drop the content you require inside a ScrollViewer, so for example adding a large TextBlock as so:
<ScrollViewer Name="scrollViewer" ScrollViewer.HorizontalScrollBarVisibility="Visible" >
<TextBlock Height="30" Name="textBlock" FontSize="24"
Text="This is a long block of text which wont fit in the available area" />
</ScrollViewer>
Obviously, in most cases you will want to drop a container control such as Grid or StackPanel into the ScrollViewer and place all your other controls in there.
That said, I'm wondering if you are actually looking for some of the standard WP7 Metro look and feel controls such as the Panorama and Pivot Controls which are available in the latest dev tools - follow that link for full details.
