Fix the Scrolling of Hub Control in Windows phone 8.1

I have used Hub control in my Windows Phone 8.1 WinRT App.
I am dynamically populating the HubSections.
I don't want to go to last Hubsection once I have reached first Hubsection and same thing applies for Last Hubsection.
Default behaviour of Hub is that it scrolls from first Hubsection to last Hubsection.
Please Help!!

I guess you are looking for FlipView add content in it using FlipViewItem.
Hope it helps! :)

If you have a method like
panHub_SectionsInViewChanged(object sender, SectionsInViewChangedEventArgs e)
where in your xaml you have:
<Hub x:Name="panHub" Style="{StaticResource HubPanoramaStyle}" Margin="0, 0, 0, 0"
SectionsInViewChanged="panHub_SectionsInViewChanged" Loaded="panHub_Loaded" Grid.RowSpan="2">
Then the SectionsInViewChangedEventArgs e will have sections that moved into view and those out.
You could try scrolling to the last section if you are going from Last to First, like panHub.ScrollToSection(LastSection);

Tooltip is not shown

I'm writing a WP 8 app and I want to display a tooltip when mouse hovers over a button or switch. I tried the following code:
ToolTip toolTip = new ToolTip();
toolTip.Content = "Flip switch to turn on.";
ToolTipService.SetToolTip(onOffSwitch, toolTip);
Also I tried to define it in XAML:
<Button Content="Msgs"
HorizontalAlignment="Left"
Margin="59,651,0,0"
VerticalAlignment="Top"
Width="108"
ToolTipService.ToolTip="tip"/>
But none of these work. When I point cursor on the control there is no tip. What did I miss?

First there is no mouse hover in windows phone 8. however if you want to add tooltips, you can refer this link

You can not add a tooltip for Windows Phone controllers. There is no way to simulate or detect a mouse/finger hover in Windows Phone.

Make WPF control over the web browser

I have a WPF application in which I have an embedded web browser control. I want to show an animation over the web browser at a certain time, but the problem is that the WPF controls, when kept over the web browser are not visible.
Is there any way to show my user control over the web browser?

Please answer me this first,
Is this Web Browser control the WPF Web Browser Control or Winform webbrowser control hosted in WinFormHost?
For any WPF control to show animation over it, did you explore ...
Placing your control in Grid or Canvas and then placing an stretched Border (which has running animation in it) as the last child of the grid/canvas?
Adorner with constantly changing drawing context to simulate animations?
Transparent Popup with animation, whose static placement is done (bound to control's absolute left, top positions and actual height & width properties) over the control?
Try the transparent popup approach for web browser control ...
<Grid>
<WebBrowser x:Name="WebBrowser1"/>
<Popup IsOpen="{Binding StartAninmation}"
AllowsTransparency="True"
Grid.RowSpan="99"
Grid.ColumnSpan="99"
Placement="Center"
Width="{Binding ActualWidth,
ElementName=WebBrowser1,
Mode=OneWay}"
Height="{Binding ActualHeight,
ElementName=WebBrowser1,
Mode=OneWay}"
PlacementTarget="{Binding ElementName=WebBrowser1}"
Opacity="0.5"
Margin="3">
<TextBlock Text="Loading ..."/>
</Popup>
</Grid>
One of these will surely work in your case.

Unfortunately thats not possible with the WPF Webbrowser Control (which is basically a wrapped WinForms WebBrowser control), due to the order the OS renders WinForms and WPF content.

Is there a way to render WPF controls on top of the wpf WebBrowser control?
There's a third party app Awsomium that should make it possible.
Edit: Another possibility would be to render a frameless window above the WebBrowser Control. But it's a bit tricky to keep it in the correct position/z-order.

CefSharp provides a pure WPF browser contorl based on Chromium/V8 that isn't subject to the airspace issues of the Microsoft WebBrowser control (disclaimer: I am the maintainer of CefSharp).

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.
