How do I edit the style of a controls flyout in blend - c#

I need to edit the design of a button-flyout but I can't find a reference to the flyout. In the Blend Object-Explorer I dont find any flyout at all:
So what's the trick to access the flyout. I saw there is a special TimePickerFlyout class https://msdn.microsoft.com/library/windows/apps/windows.ui.xaml.controls.timepickerflyout.aspx in UWP, but if I search for it inside my template or the project code, the only thing I find is TimePickerFlyoutButtonStyle in the Templates Ressources which, in my understanding, contains the storyboard information for the Buttons appearance.

I did the following to change the TimePickerFlyout's background colour and the size of the buttons on its footer.

How To increase the calendar icon size of CalendarDatePicker and customising it with different text or image icon [UWP]?

I tried changing the calendar icon size but couldn't find a property to achieve this.

You could edit the default CalendarDatePicker style and change CalendarGlyph FontIcon's FontSize and Glyph property like the following.

Is there any known reasons my GUIs controls change after changing to target version 17314, from 15063?

My application uses a pivot menu. The pivot menu items contain a user control which is a page, so you click on a pivot item, and it brings you to the detail page of that pivot, sort of like master/detail style.
I want to upgrade my target version to the version 17134, but when I do this I get some strange behavior with the controls. The border within the pivot in 15063 version adjusts its size depending on the content. In 17134, its not adjusting it's size to the content.
I've tried setting height=auto on scrollviewer which is the holder of the content presenter in the pivot.
I've tried many different things with heights on the various controls, but no luck. Any help is much appreciated.
This is the pivot

This is the expected behavior, and the behavior with version 15063. If i take the grid out, the border will adjust its size to fit the content.
This is the result of version 17314. The border does not adjust to the size anymore, and seems to be controlled by magic, as it does it's own thing.
UPDATE
After downloading the sdk for 16299, the unexpected behaviors went away. The target version 17134 still causes the unexpected behavior.

I'm not an expert at RadDataGrid but it seems to me from looking at this question/answer for it (https://www.telerik.com/forums/raddatagrid-and-scroll-bar), it contains its own ScrollViewer for data. That means you don't need the ScrollViewer in your Pivot's DataTemplate.
Second, your StackPanel inside your BaseControl won't tell the containing controls what its Height is... because it will keep expanding to fit the contents. So, your RadDataGrid is not using its ScrollViewer at all in this case. I'd expect your weird height/margin issues to be related to how the different versions of the 'ScrollViewer' / 'StackPanel' and RadDataGrid negotiate their respective sizes.
It might go away if you remove the ScrollViewer and replace the StackPanel with a Grid containing two RowDefinitions... one with Auto height and the second with * height.
Something like this:
<local:BaseControl
x:Class="LD75ClaimSystem.UI.View.IncomeDetailsView"

How to increase the height of the UWP calender date picker?

I have added UWP calendar date picker. Here is the XAML code
<CalendarDatePicker Background="White" Grid.Row="6" Width="660" VerticalAlignment="Stretch" FontSize="48" PlaceholderText="Date of Birth" Padding="0" Margin="0" x:Name="DobDatePicker"></CalendarDatePicker>
But the problem is that I can't change the height of that calendar textblock control(not the pop up). I tried by setting the minimum height, but it does n't work. Is there any way to fix this issue?

CalenderDatePicker has hardcoded value(32) for its rowdefinition in default style. So, You can modify that particular part of the CalenderDatePicker default style to change the height.
//Portion to modified
<Style TargetType="CalendarDatePicker">
....
....
<Grid x:Name="Root">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="32" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="32" /> /* change your value */
</Grid.RowDefinitions>
....
....
</Style>

UWP User Control Unable to instatiate MyUserControl

My Uwp app builds and runs correctly. The User Control is visible in the user control designer. When I initially add the control to my main page the control is visible in the designer. I run the app and come back to main Page designed and the User Control has vanished and the xaml says "Unable ti instaiate an object of type user Control. I don;t understand why the control is visible in the user control designer but not the main page designer AND the app runs fine.
Has anybody else come across this problem? is there a clue to where I might find issues in the user control?
The XAML for the user control:

Changing Slider's Height

I have a slider. When I set its height, the selection border changes but the slider height is still the same (22px).
Here's a screenshot:
I believe that I need to change some properties in the default style but I couldnt understand what - I want to make the height dynamic - if I change to 200 it will be 200, if I change to 158 it will be 158 and so on...
I succeed to change the height to something specific by changing the HorizontalThumb Height to specific height (changed to different height than what I set)

UPDATE 2
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition x:Name="SliderRow" />
<RowDefinition Height="0.5*" />
<RowDefinition Height="0.1524*" />
</Grid.RowDefinitions>
<Button Click="Button_Click_1" Content="Mail" Visibility="Collapsed" />
<Slider Height="{Binding Path=ActualHeight,ElementName=SliderRow}" Style="{StaticResource MyCustomSlider}"/>
</Grid>
UPDATE 1
Ok, I got what you want. You want to increase the track height as well when you increase height of slider itself. Then you need to customize the slider. I replaced {StaticResource SliderTrackThemeHeight} with {TemplateBinding Height}, so when slider's height is increased the slider track will also be increased.

Usage
<Slider Height="72" VerticalAlignment="Center" HorizontalAlignment="Center" Width="500" Style="{StaticResource MyCustomSlider}"/>
Slider's track height is assigned via standard style & resource. Its key is SliderTrackThemeHeight and default is 11. So you need to write below line in App.xaml ONLY and whenever you want to change it you can access the resource and change it.
<x:Double x:Key="SliderTrackThemeHeight">50</x:Double>
You can set from code behind like this.
Application.Current.Resources["SliderTrackThemeHeight"] = YOUR_DYNAMIC_VALUE;
