Answer 1

It's because of your resolution you have to change your form's dimensions and it will fit.

Answer 2

Try adding the code below in your <StackPanel> tag on the Page1.xml side of your code.

<StackPanel.Resources>
     <Style x:Key="StackPanelMargining" TargetType="Control">
        <Setter Property="Margin" Value="0,0,0,0"/>
     </Style>
     <Style BasedOn="{StaticResource StackPanelMargining}" TargetType="Your Target Element"/>
</StackPanel.Resources>

Answer 3

Not sure exactly what your asking.

If you want your window to be above all other windows on the OS you can use the IsTopMost=true parameter.

If you want one element on your window to be shown above something else this is the Z-Order. In WPF the Z-Order is defined by the order the elements appear in your XAML. For instance if you create a button, then an image the image would be placed above the button, because the image is defined further down in the XAML.
