I'm getting this error while trying to develop my app, the compilator said that it could not find an error code. So I don't have more information. I know that the error is generated while trying to initializeComponent.
Here is the code of my page:

After a long time of trying and error, I found where is the issue located. In the deepest Grid, the error is generated while trying to create TextBox, don't know why because if you just delete textBox it works properly.

Thanks for helping.

Pay attention to this two lines:
<TextBox Grid.Row="1" Grid.Column=" 0" x:Name="nifBox" PlaceholderText="DNI..." FontSize="20" Background="Gray" VerticalAlignment="Center" Margin="29,0,30,0" />
<TextBox x:Name="nameBox" Grid.Row="3" Grid.Column=" 0" PlaceholderText="Nombre..." FontSize="20" Background="Gray" VerticalAlignment="Center" Margin="30,0,30,0" />
You have an extra space before 0 value in the Grid.Column. You need to pass "0" instead of " 0".

UWP: Listview when loaded for first time shows a grey background for less than a second and then disappears before the actual content

Whenever the listview is loaded for the first time, it displays a flash of grey background for less than half a second and then disappears before the actual content is loaded. My code is as follows (pretty straight forward) Any thoughts?

UWP Navigation Pane Issues

I am looking for a way to create a navigation pane using SplitView and other XAML controls.
I have tried creating something like the code below, but I failed as the controls aren't placed precisely in the center (vertically).
Also the buttons have this weird default animation that skews them when they are clicked. I want to turn it off but I don't know how.
All in all, I want to create a hamburger menu that is similar to Start menu in Windows 10 Anniversary Update. All opinions would be pretty appreciated.
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<SplitView x:Name="hamburgerMenu" HorizontalAlignment="Left" Width="319" DisplayMode="CompactOverlay">
<SplitView.Pane>
<StackPanel>
<Button x:Name="HamburgerButton" Width="320" Height="48" Click="HamburgerButtonClick" BorderThickness="0" Background="{x:Null}" HorizontalContentAlignment="Left">
<StackPanel Orientation="Horizontal" Margin="-8,0,0,0">
<TextBlock Width="48" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" Margin="0,1,0,0" />
<TextBlock Text="MENU" Margin="0,0,0,0" FontWeight="Bold" />
</StackPanel>
</Button>
<Button x:Name="TasksButton" Width="320" Height="48" BorderThickness="0" Background="{x:Null}" HorizontalContentAlignment="Left">
<StackPanel Orientation="Horizontal" Margin="-8,0,0,0">
<TextBlock Width="48" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" VerticalAlignment="Center" />
<TextBlock Text="Tasks" Margin="0,0,0,0"/>
</StackPanel>
</Button>
<Button x:Name="ArchivedButton" Width="320" Height="48" BorderThickness="0" Background="{x:Null}" HorizontalContentAlignment="Left">
<StackPanel Orientation="Horizontal" Margin="-8,0,0,0">
<TextBlock Width="48" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" VerticalAlignment="Center" />
<TextBlock Text="Archived" Margin="0,0,0,0"/>
</StackPanel>
</Button>
</StackPanel>
</SplitView.Pane>
</SplitView>
</Grid>
Here is what I want to achieve:

MessiKing's Template 10 is a good idea and will save you a lot of time. No doubt in that. But that doesn't help you learn how XAML handles controls because they are all handled already by experts. However if you want to learn how it works in pure XAML without any 3rd Party Libraries, see below.
Your XAML will look something like below
<SplitView x:Name="hamburgerMenu" HorizontalAlignment="Stretch" OpenPaneLength="150" DisplayMode="CompactOverlay" IsPaneOpen="True">
<SplitView.Pane>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button x:Name="HamburgerButton" Click="HamburgerButtonClick" Style="{StaticResource TextBlockButtonStyle}" FontWeight="Bold" VerticalAlignment="Top">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" >
<TextBlock FontSize="20" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" Padding="5" />
<TextBlock Text="MENU" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="15,0"/>
</StackPanel>
</Button>
<Grid Grid.Row="1" x:Name="btmtp" VerticalAlignment="Top">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Button x:Name="TasksButton" Style="{StaticResource TextBlockButtonStyle}" Grid.Row="1">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<TextBlock FontSize="20" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" Padding="5" />
<TextBlock Text="Tasks" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="15,0"/>
</StackPanel>
</Button>
<Button x:Name="ArchivedButton" Style="{StaticResource TextBlockButtonStyle}" Grid.Row="2">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<TextBlock FontSize="20" FontFamily="Segoe MDL2 Assets" Text="" TextAlignment="Center" Margin="5" />
<TextBlock Text="Archived" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="15,0"/>
</StackPanel>
</Button>
</Grid>
</Grid>
</SplitView.Pane>
</SplitView>
Output
Now for the styling for buttons. Default Styling provided by Microsoft includes a StaticResource called TextBlockButtonStyle which will change your button styling to that of a TextBlock. Take a look at this.
Also there is a reason why I wrapped the List Items inside a Grid. because if you change
<Grid Grid.Row="1" x:Name="btmtp" VerticalAlignment="Top">
to
<Grid Grid.Row="1" x:Name="btmtp" VerticalAlignment="Bottom">
you will see it something like below.
Good Luck and Happy Coding.

Dziewulski,
If you want to make a hamburgerMenu, using Template 10 would save you much time.
When you install the Template 10 in visual studio, you will be easy to create a project which contained a hamburgerMenu in it.
Please refer to these videos for details:Template 10 for Windows 10 Apps
Template 10: How to Build Your Universal Windows App

try the UWP Toolkit from Microsoft. It contains a hamburger menu:

How to align the textblocks in listview of windows phone 8.1

!
I need to align the textblocks(PhoneTxt, CreateddateTxt ) which is present in listview.
<Grid Grid.Row="1" x:Name="ContentRoot" Margin="19,9.5,19,0">

<TextBlock Margin="5,0,0,0" Grid.Row="0" x:Name="NameTxt" TextWrapping="Wrap" Text="{Binding Events}" FontSize="28" Foreground="White"/>
<TextBlock Grid.Row="0" Text=">" FontSize="28" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="White"/>
<TextBlock Margin="5,0,0,0" Grid.Row="1" Name="PhoneTxt" TextWrapping="Wrap" Foreground="White" FontSize="18" Text="{Binding diff}" />
<TextBlock Margin="0,0,35,0" Grid.Row="2" Name="CreateddateTxt" Foreground="White" FontSize="18" TextWrapping="Wrap" Text="{Binding result}" />

#Schuere There is an big gap between them..After appplying your code
I need to display .(i.e in output)Print them as together each other in a same row with some space..
# fillobotto I need to display those textblocks together with one or two spaces in between them

Try this
<ListBox Background="Transparent" HorizontalAlignment="Left" Height="auto" BorderThickness="1" MaxHeight="580" Grid.Row="1" Margin="6" VerticalAlignment="Top" Width="352" Name="DaysLeftListView" SelectionChanged="DaysLeftListView_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Width="350" >
<Border Margin="5" BorderBrush="White" BorderThickness="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0" Orientation="Horizontal">
<TextBlock Margin="5,0,0,0" x:Name="NameTxt" TextWrapping="Wrap" Text="{Binding Events}" FontSize="28" Foreground="White"/>
<TextBlock Text=">" FontSize="28" Margin="5,0,0,0" Foreground="White"/>
</StackPanel>
<StackPanel Grid.Row="1" Orientation="Horizontal">
<TextBlock Margin="5,0,0,0" Name="PhoneTxt" TextWrapping="Wrap" Foreground="White" FontSize="18" Text="{Binding diff}" />
<TextBlock Margin="5,0,0,0" Name="CreateddateTxt" Foreground="White" FontSize="18" TextWrapping="Wrap" Text="{Binding result}" />
</StackPanel>
</Grid>
</Border>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Orientation="Horizontal" was missing

create some extra columndefinitions:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinitions Width="Auto"/>
<ColumnDefinitions Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Margin="5,0,0,0" Grid.Row="0" Grid.Column="0" ColumnSpan x:Name="NameTxt" TextWrapping="Wrap" Text="{Binding Events}" FontSize="28" Foreground="White"/>
<TextBlock Grid.Row="0" Grid.Column="1" Text=">" FontSize="28" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="White"/>
<TextBlock Margin="5,0,0,0" Grid.Row="1" Grid.Column="0" Name="PhoneTxt" TextWrapping="Wrap" Foreground="White" FontSize="18" Text="{Binding diff}" />
<TextBlock Margin="0,0,35,0" Grid.Row="1" Grid.Column="1" Name="CreateddateTxt" Foreground="White" FontSize="18" TextWrapping="Wrap" Text="{Binding result}" />
</Grid>
This should change the outcome, the CreateddateTxt should be right next to PhoneTxt

I don't understand perfectly which TextBlock you want to align, but you shoud use a StackPanel control and set its Orientation property to Horizontal.
<ListBox Background="Transparent" HorizontalAlignment="Left" Height="auto" BorderThickness="1" MaxHeight="580" Grid.Row="1" Margin="6" VerticalAlignment="Top" Width="352" Name="DaysLeftListView" SelectionChanged="DaysLeftListView_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Width="350" >
<Border Margin="5" BorderBrush="White" BorderThickness="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Margin="5,0,0,0" Grid.Row="0" x:Name="NameTxt" TextWrapping="Wrap" Text="{Binding Events}" FontSize="28" Foreground="White"/>
<TextBlock Grid.Row="0" Text=">" FontSize="28" HorizontalAlignment="Right" VerticalAlignment="Center" Foreground="White"/>
<StackPanel Grid.Row="1">
<TextBlock Margin="5,0,0,0" Name="PhoneTxt" TextWrapping="Wrap" Foreground="White" FontSize="18" Text="{Binding diff}" />
<TextBlock Margin="5,0,0,0" Name="CreateddateTxt" Foreground="White" FontSize="18" TextWrapping="Wrap" Text="{Binding result}" />

<view:Content ...> tags in XAML

I inherited some code where I've seen this construction, which I'm not used to, in several locations:
<view:Content x:Name="TimeFrame" Margin="220,50,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" >
<view:Content.ChildContent>
<view:TimeFrame />
</view:Content.ChildContent>
</view:Content>
Which I must admit seems rather nifty, and thus far works as I want it too. However, then there's this where instead of the <view:TimeFrame />-tag in the center there are a regular control-tags like so:
<view:Content x:Name="SignInControl" Margin="466,317,0,0" HorizontalAlignment="Left" Width="348" Height="344" VerticalAlignment="Top">
<view:Content.ChildContent>
<Grid>
<Border CornerRadius="8,8,0,0" BorderThickness="1" Width="270" Height="300" Background="#666666" Margin="1,0,-1,0" Opacity="0.57" >
<Border.Effect>
<BlurEffect/>
</Border.Effect>
</Border>

</StackPanel>
</Grid>
</Border>
</Grid>
</view:Content.ChildContent>
</view:Content>
When I attempted to give the controls here names so that I could access them in code I got the following error:
Cannot set Name attribute value 'txtBox_username' on element 'TextBox'. 'TextBox' is under the scope of element 'Content', which already had a name registered when it was defined in another scope.
I don't know if it's possible to access these members in some other way through the Content scope but if anyone would enlighten me I would be grateful. Either way I'd really like a link to a relevant MSDN page(or other resource) as I can't seem to figure out what to search for in order to learn more about type tags.
Thanks

This behaviour is caused by how UserControls are implemented, see this question for workarounds.
