How to make user control like application bar - windows phone

My question seems to be a bit strange. I have a long list selector and I want to add a control like application bar in it so it can be repeated many times the same with the controls in the item template. I thought about a grid with the contents I want, but how can I make this Grid slides up and down ?

Yeah, it is strange but you can certainly try it. There is no definite way to do this but you can create a user control that would be the application bar like element you want and add it to the list selector. But the biggest problem is make it slide up and down. In the user control you can do this easily but there are many ways you can do this. You have to try it out and see. Use animations and story boards to animate the sliding effect. This can be done using Blend for Visual Studio. But you might run in to a problem where even though you did the animation of your application bar sliding in your Application bar like user control, it might not work in the list selector because the layout and the size of a single list item needs to change as the user expands the user control to have the sliding effect. As i said, there are many ways one can do this. You have to try it out and build it.

List item
In App.xaml type in this code
<Application.Resources>
<shell:ApplicationBar x:Key="UserControlAppBar" ForegroundColor="White" BackgroundColor="Black" IsVisible="True" IsMenuEnabled="True">
<shell:ApplicationBarIconButton x:Name="button1" IconUri="/Assets/Images/appbar/img1.png" Text="News" Click="button1_Click"/>
<shell:ApplicationBar.MenuItems>
<shell:ApplicationBarMenuItem x:Name="MenuItem" Text="Menu1" Click="Menu1_Click"/>
</shell:ApplicationBar.MenuItems>
</shell:ApplicationBar>
</Application.Resources>

Windows Phone 8.1 black space below application bar on 720p devices [duplicate]

Whenever i added the menu items in app bar, an extra line or space is coming under the menu items. I don't know how to remove it. It really disturbs look a lot. herewith i have added that menu by image. Kindly, help me to get rid of that extra space.
My XAML CODE:
<phone:PhoneApplicationPage.ApplicationBar>
<shell:ApplicationBar Mode="Default" Opacity="1.0" IsMenuEnabled="True" IsVisible="True">
<shell:ApplicationBarIconButton IconUri="/Assets/folder.png" Text="about" Click="more1"/>
<shell:ApplicationBarIconButton IconUri="/Assets/next.png" Text="goto" Click="gotopage"/>
<shell:ApplicationBar.MenuItems>
<shell:ApplicationBarMenuItem Text="rate this app" Click="rateapp"/>
<shell:ApplicationBarMenuItem Text="like us" Click="like"/>
</shell:ApplicationBar.MenuItems>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
OUTPUT APP BAR BY ABOVE CODE:

To my knowledge, it's the default behavior of the application bar to have this space when there are 2 or less menu items. You can get rid of the space by adding another menu item (throw in a help or about us or something) so that you have 3 menu items, or by creating your own application bar. The second route seems really overkill for such a small issue though.

At the moment the App Bar only has a few sizes that it will display. one item, three items, and five items. Thus why you get an extra space if you have 4 items or 2 items.

How can i mark menuitem in Application Bar Windows Phone 7

How can i mark menuitem in Application Bar. I want to get, for example, this:

You can change the template of the MenuItem.Header, as described in this tutorial. For example:
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu>
<toolkit:MenuItem Header="AddItem"/>
<!-- a templated menu item -->
<toolkit:MenuItem>
<toolkit:MenuItem.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Delete Item"/>
<Image Source="Images/appbar.delete.rest.png"/>
</StackPanel>
</toolkit:MenuItem.Header>
</toolkit:MenuItem>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>

I'd say it can't be done. The menu items are just calls to functions and can do nothing but show the corresponding text and call the corresponding method when activated. I've found some examples of people hacking extra functionality into them (updating the text or changing the function calls, to some extent), but nothing beyond that would be possible.
Notice that what you can do with the AppBar is limited by the functionality offered by IApplicationBar and, in your case, ApplicationBarMenuItem. And none of them expose anything even close to your requirements.
You can, however, enable and disable menu items, although I don't think that's what you want.

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.
