Docking Windows Phone controls to the bottom of a StackPanel - xaml

Is there a way to dock a Windows Phone control to the bottom of a StackPanel? This is my basic layout:
<StackPanel Orientation="Vertical">
<TextBlock />
<TextBlock />
<UI:AdControl />
</StackPanel>
My StackPanel is filling up the whole window. The TextBlocks are aligned toward the top of the panel, that's what I want.
But I want the AdControl to dock at the bottom of the StackPanel (and therefore the bottom of the window).
I've found controls like DockPanel, but they seem to only work for WPF or Silverlight as far as I can tell.

This can easily be accomplished with a simple grid
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
<Grid.RowDefinitions>
<StackPanel>
<TextBlock />
<TextBlock />
</StackPanel>
<UI:AdControl Grid.Row="1"/>
</Grid>
If you want exactly DockPanel for future use, make sure you look into open source implementations, there should be plenty of those out there!

uwp xbox app XYNavigation in Pivot Control

I am an experienced uwp developer but a beginner for uwp xbox platform. I am trying to set the XY Navigation for my app and trying to test it with keyboard (as I don't own a xbox myself).
I am using a Pivot view and I can easily navigate between the pivot items with right and left arrow keys, which makes sense. but when my settings page is selected with pivot option (settings pivot header is focused and settings pivot item is in view) then I try to shift my focus vertically downwards to the first control in the settings page (radio buttons) but I am not able to do it the focus remains on settings header and doesn't shift downward on the page.
So how can I shift the focus downwards from a pivot header to the 1st control within the page on pressing down, and vice versa i.e : when 1st control is focused I should move up to go back to the header of the pivot of that page, because I think that is the traditional navigation with pivot control on uwp xbox right?
Secondly the docs and the xbox app dev videos I watched recommended to set the focus on an element which makes sense, when the app loads, should that be done with this.Focus() method or is there a more efficient way to do it with xaml?
Code:
Pivot.xaml
<Grid x:Name="MainGrid">
<Pivot x:Uid="PivotPage" x:Name="MainPivot" >
<PivotItem x:Uid="PivotItem_OnNow">
<Frame>
<views:OnNowPage/>
</Frame>
</PivotItem>
<PivotItem x:Uid="PivotItem_Guide">
<Frame>
<views:GuidePage/>
</Frame>
</PivotItem>
<PivotItem x:Uid="PivotItem_Settings">
<Frame>
<views:SettingsPage/>
</Frame>
</PivotItem>
</Pivot>
</Grid>

<Grid Margin="{StaticResource MediumLeftRightMargin}">
<Grid.RowDefinitions>

The MSDN has listed several scenarios that XY navigation might not work the way you expect:
The IsTabStop or Visibility property is set wrong.
The control getting focus is actually bigger than you think—XY navigation looks at the total size of the control (ActualWidth and ActualHeight), not just the portion of the control that renders something interesting.
One focusable control is on top of another—XY navigation doesn't support controls that are overlapped.
If XY navigation is still not working the way you expect after fixing these issues, you can manually point to the element that you want to get focus using the method described in Overriding the default navigation.
Please first check these scenarios, after that, if you still could not solve this issue. Please provide a Minimal, Complete, and Verifiable example. I will help you diagnose it on my side.

AutoSuggestBox opens up off screen

I have probably the most basic implementation of AutoSuggestBox I can think of.
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid x:Name="SearchBoxContainer">
<AutoSuggestBox
PlaceholderText="Type a topic name"
Margin="8"
QueryIcon="Find"
DisplayMemberPath="Title"
TextChanged="AutoSuggestBox_TextChanged"
QuerySubmitted="AutoSuggestBox_QuerySubmitted"
SuggestionChosen="AutoSuggestBox_SuggestionChosen"
ItemsSource="{Binding MatchingTopics}"
/>
</Grid>
</Grid>
When typing in, I get a suggestion list. But it appears ABOVE the autoSuggestBox. The problem is that because I have placed the AutoSuggestBox at the top of the screen already, the suggestion list goes off screen so I can only see one item!
Is it possible to control the direction of the AutoSuggestBox so that it will expand downwards? Why doesn't the AutosuggestBox select the right direction based on available screen real estate?

How do I enable Scrollbars on a UWP GridView

I have a UWP where I am loading from an XML file and showing it in a GridView and I am trying to enable Scrollbars in a way that allows me to stack and wrap items in all the available space like in the image below. The problem that I am having is that I cannot figure out how to enable the scrollbars so that I can scroll the boxes until I get to the end of the list.
So far I have got it to do what you see in the picture, which is wrapped the way I want but it fills all the available space and doesn't allow you to scroll vertically or horizontally (I only want to scroll one way but I have tried to see if I could go either way). Through a lot of trial and error I was able to get it to scroll one row or one column at a time to the end of the list but that is not the desired result either. Here is where I am with the XAML right now (trimmed down version of the screen shot).
<GridView x:Name="DataGrid1">
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid Orientation="Horizontal"
ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.VerticalScrollBarVisibility="Disabled" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemTemplate>
<DataTemplate>
<Border Width="270"
Height="200"
Margin="5"
BorderBrush="Black"
BorderThickness="2">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="70" />
<ColumnDefinition Width="100*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<StackPanel Grid.Row="0"
Grid.Column="0"
Grid.ColumnSpan="2"
Background="#87CEFA">
<TextBlock Margin="2"
HorizontalAlignment="Center"
FontSize="16"
FontWeight="Bold"
Text="{Binding Company}" />
</StackPanel>
<TextBlock Grid.Row="1"
Grid.Column="0"
Margin="2"
HorizontalAlignment="Right"
FontWeight="Bold"
Text="Code: " />
<TextBlock Grid.Row="1"
Grid.Column="1"
Margin="2"
Text="{Binding Code}" />
</Grid>
</Border>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
So what do I need to do to enable the scrollbars the way that I want?
Make sure your GridView is in a Grid and not a StackPanel. It does not expand in a StackPanel.
To make it scroll in a StackPanel you have to specify the height of the GridView. This was the issue with mine :)
To my knowledge gridviews that are not showing scrollbars automatically are due to stackpanel's presence. So my solution here is to try remove stackpanel what so ever, and if I find the stackpanel that's responsible replace it with other kind of panel and work my way back up. It's totally a brute force kind of approach but it works most of the time.
And another piece of advice. In that process of replacing the stackpanel try to replace it with grid and try to divide it's rows and columns with widths and heights set to auto or star sizing instead of specifying it with actual numbers to see if it works this way. If it works then work your way up speicifying it with actual numbers.
Here's your problem, in the definition of the ItemsWrapGrid you have:
ScrollViewer.VerticalScrollBarVisibility="Disabled"
this is going to mean that even if the scrollbar is shown it wont work.
Remove this line and you should get a working scrollbar.

grid inside scrollviewer in windows phone 7.1

i need a registeration form within my application, i need scrolling so i did the following
<ScrollViewer VerticalScrollBarVisibility="Visible" Height="780" MaxHeight="1800"
MaxWidth="477" VerticalAlignment="Top">
<ScrollViewer.Content>
<Grid Width="477" Height="728" MaxHeight="1800">
<!-- .......Form's Elements..... -->
</Grid>
</ScrollViewer.Content>
</ScrollViewer>
there is no scrolling, what am i missing?
You shouldn't set the height properties when working with a ScrollViewer. If you strip it down to just the following and it still doesn't work, then it is something else in your project that is preventing it to work.
<ScrollViewer>
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Text="Hello" FontSize="320" />
<TextBlock Grid.Row="1" Text="World" FontSize="320" />
</Grid>
</ScrollViewer>
Remove the ScrollViewer.Content - part, I have an app that has this structure and it works fine:
<ScrollViewer x:Name="ContentScrollViewer" Margin="0,0,0,8">
<Grid Height="562">
<!-- My elements -->
</Grid>
</ScrollViewer>
Your scrollviewer has a height of 780 and your grid is only 728. Why would there be any scrolling? You'll only be able to scroll if the grid is higher than 780.

long text cropped in textblock

I've a problem. I've a textblock and my text is cropped. It seems to appear only when the text is too long cause when the text is shorter, there is no problem.
So there is my code :
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Grid.RowDefinitions>
<RowDefinition Height="150" />
<RowDefinition Height="447*" />
</Grid.RowDefinitions>
<Image Grid.Row="0" Source="{Binding TheContent.PathPicture}" />
<ScrollViewer Grid.Row="1">
<Grid>
<TextBlock Text="{Binding TheContent.Text}" TextWrapping="Wrap" FontSize="24" />
</Grid>
</ScrollViewer>
</Grid>
Text is croping like this :
Is the only solution to summary my content ?
The depth of a single textblock is limited to about 2000 pixels on WP7. You need to divide up your text into multiple blocks to display it all.
Controls are limited to 2k square, but there's a fairly straight forward resolution in breaking your text up and presenting the blocks in a stackpanel and wrapping that in a ScrollViewer.
Alex Yakhnin demonstrates here.
