Pop-up content after clicking on an item from the wpf list

I need to implement this drop-down menu in WPF:
When you click on the number of the question, it should open additional content. I can't attach the code, because there is not even an approximate implementation. I tried to implement via Grid.Row and Grid.Column, ListBox, StackPanel but I just didn't have enough knowledge.
Here is the code I've tried:
<Grid>
<ListBox HorizontalContentAlignment="Left">
<Button Content="1"/>
<TextBlock Text="Content"/>
<Button Content="2"/>
</ListBox>
</Grid>

Step 1: Add a User Control to your project.
Step 2: Name it Arrow.
Step 3: This Control will act as a drop-down arrow for us. Add the following XAML code to the control:
<UserControl x:Class="Question_Builder_App.Controls.Arrow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d">
<Grid>
<Border BorderThickness="0,0,5,0" Height="15" BorderBrush="Black" RenderTransformOrigin="0.5,0.5" Width="10" Margin="0,0,0,10">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="135"/>
<TranslateTransform/>
</TransformGroup>
</Border.RenderTransform>
</Border>
<Border BorderThickness="0,0,5,0" BorderBrush="Black" RenderTransformOrigin="0.5,0.5" Height="15" Width="10" Margin="0,11,0,0" Grid.RowSpan="2">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="225"/>
<TranslateTransform/>
</TransformGroup>
</Border.RenderTransform>
</Border>
</Grid>
The control should look like this:
Step 4: Add the following XAML to your MainWindow:
<Window x:Class="Question_Builder_App.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800" Background="#FF283246">
<Grid x:Name="MainGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<StackPanel x:Name="LeftPanel" Grid.Column="0">
<Border CornerRadius="10,10,10,10" HorizontalAlignment="Center" VerticalAlignment="Center" Background="#FF033B50" Margin="50,20,50,0">
<Button x:Name="AddQuestion_BTN" FontSize="24" Content="+" HorizontalAlignment="Stretch" VerticalAlignment="Center" Foreground="White" HorizontalContentAlignment="Left" Padding="10,0,10,0" Click="AddQuestion_BTN_Click" Background="{x:Null}" BorderBrush="{x:Null}"/>
</Border>
</StackPanel>
<Frame x:Name="RightPanel" Grid.Column="1" NavigationUIVisibility="Hidden"/>
</Grid>
The designer should look like this:
Step 5: Now lets add some C# codes to our MainWindow:
using System.Collections.ObjectModel;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
namespace Question_Builder_App

How to get Text-Marquee to fade in and out smoothly in WPF

I have a WPF Canvas with a TextBlock and an Image on it. The text is animated, but it doesn't look smooth. I tried many combinations of different FPS-Settings and durations but it won't get better.
I also want to let the text fade-in/out at the start and ending. But I found no methods to do so.
At the moment it looks like that:
How can I get the animation smoothly? How can I fade it in/out smoothly?
Before you ask, I need to show the Window invisible because I use the WpfAppBar and that component needs an HWND.
Here is the canvas xaml:
<Canvas x:Name="canMain" HorizontalAlignment="Stretch" VerticalAlignment="Center">
<Border x:Name="boLogo" Panel.ZIndex="2" Height="40" Background="Gray" Canvas.Left="0" Canvas.Top="-20">
<Image Height="39" Width="auto" Margin="5, 0, 5, 0" Source="pack://siteoforigin:,,,/Resources/Logo.png" />
</Border>
<TextBlock x:Name="tbInfo" Panel.ZIndex="1" Visibility="Hidden" RenderOptions.BitmapScalingMode="NearestNeighbor" FontSize="32" TextOptions.TextFormattingMode="Display" TextOptions.TextRenderingMode="ClearType" FontFamily="Arial" FontWeight="Bold" Padding="5" HorizontalAlignment="Stretch" VerticalAlignment="Center">
<TextBlock.RenderTransform>
<TranslateTransform x:Name="AnimatedTranslateTransform" X="0" Y="0" />
</TextBlock.RenderTransform>
</TextBlock>
</Canvas>
And the code to animate the text:
public void ShowWindow(Brush fontColor, Brush backgroundColor, string str) {
var helper = new WindowInteropHelper(this);
helper.EnsureHandle();
tbInfo.Foreground = fontColor;
this.Background = backgroundColor;
tbInfo.Text = str;
this.Height = 39;
this.Width = SystemParameters.WorkArea.Width;
this.Left = SystemParameters.PrimaryScreenWidth - this.Width;
ShowWindowInvisible();
WpfAppBar.AppBarFunctions.SetAppBar(this, WpfAppBar.ABEdge.Top);
Visibility = Visibility.Visible;
int duration = 10 + str.Length / 5;
TextMarquee(duration);
}
private void TextMarquee(int duration)
{
Timeline.DesiredFrameRateProperty.OverrideMetadata(
typeof(Timeline),
new FrameworkPropertyMetadata { DefaultValue = 60 }
);
double height = canMain.ActualHeight - tbInfo.ActualHeight;
tbInfo.Margin = new Thickness(0, height / 2, 0, 0);
DoubleAnimation doubleAnimation = new DoubleAnimation();
doubleAnimation.From = canMain.ActualWidth;
doubleAnimation.To = tbInfo.ActualWidth *-1;
doubleAnimation.RepeatBehavior = RepeatBehavior.Forever;
doubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(duration));
tbInfo.BeginAnimation(Canvas.LeftProperty, doubleAnimation);
tbInfo.Visibility = Visibility.Visible;
}
private void ShowWindowInvisible()
{
var width = Width;
var height = Height;
var windowStyle = WindowStyle;
var showInTaskbar = ShowInTaskbar;
var showActivated = ShowActivated;
Width = 0;
Height = 0;
WindowStyle = WindowStyle.None;
ShowInTaskbar = false;
ShowActivated = false;
Show();
Visibility = Visibility.Hidden;
Width = width;
Height = height;
WindowStyle = windowStyle;
ShowInTaskbar = showInTaskbar;
ShowActivated = showActivated;
}

UI difference between XAML and C# code behind

I have built a UI block in XAML that will represent a customizable web page test automation. No problem so far.
I'm now trying to translate these UI elements from XAML to the C# code behind, so I can generate the UI blocks dynamically, and there are differences I can't explain: several element are not displayed when generated from the code behind.
Screenshot for comparison:
XAML code:
<StackPanel x:Name="TestPanel" Orientation="Vertical" Grid.RowSpan="2">
<Grid Margin="0,20,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="100*"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<CheckBox Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" Margin="10,0,0,0">Page link here</CheckBox>
<TextBlock Grid.Column="2" Grid.Row="0" Margin="0,0,10,0">Status here</TextBlock>
<CheckBox Grid.Column="0" Grid.Row="1" Margin="30,8,0,0">Url to check:</CheckBox>
<TextBox Grid.Column="1" Grid.Row="1" Margin="5,5,5,0">Url here</TextBox>

Thanks

I second the suggestion that you should create a User Control and reuse that. However, to answer the question directly, you need to set the Column and Row Width and Height properties to Auto.
// Columns
this.Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto });
ColumnDefinition col = new ColumnDefinition();
col.Width = new GridLength(100, GridUnitType.Star);
this.Grid.ColumnDefinitions.Add(col);
this.Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto });
// Rows
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });

The problem is you arent setting the height or the rows and width of the columns inside your layout grid. The default height/width isnt auto but * size.
So this code:
// Columns
this.Grid.ColumnDefinitions.Add(new ColumnDefinition());
ColumnDefinition col = new ColumnDefinition();
col.Width = new GridLength(100, GridUnitType.Star);
this.Grid.ColumnDefinitions.Add(col);
this.Grid.ColumnDefinitions.Add(new ColumnDefinition());
// Rows
this.Grid.RowDefinitions.Add(new RowDefinition());
this.Grid.RowDefinitions.Add(new RowDefinition());
this.Grid.RowDefinitions.Add(new RowDefinition());
Should be :
// Columns
this.Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto });
this.Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(100, GridUnitType.Star) });
this.Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto });
// Rows
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
this.Grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });

Scale child back in WPF

I have a Grid which scaled/zoomed with ScaleTransform by slider. At runtime many UIElements are added to this Grid.
I want to show some tooltips, but not scaled! How should I do that?
For the example: Grid has scaleX and scaleY 2, so I set new ScaleTransform(0.5, 0.5), but didn't help. It seems that the most similar value is 0.740.. Why?
Even Grid's LayoutTransform.Inverse is set to scale values 0.5.
XAML:
<ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="Auto" Width="Auto" Name="graphScrollViewer" ScrollChanged="graphScrollViewer_ScrollChanged">
<Grid Margin="0,0,0,0" Name="graphGrid" Width="Auto" Height="Auto" ScrollViewer.IsDeferredScrollingEnabled="True" MouseLeftButtonDown="graphGrid_MouseLeftButtonDown" MouseLeftButtonUp="graphGrid_MouseLeftButtonUp" MouseMove="graphGrid_MouseMove">
<Grid.LayoutTransform>
<ScaleTransform ScaleX="{Binding ElementName=sldZoom, Path=Value}" ScaleY="{Binding ElementName=sldZoom, Path=Value}" />
</Grid.LayoutTransform>
</Grid>
</ScrollViewer>
<Slider Minimum="0.1" Maximum="20" Value="1" x:Name="sldZoom" Panel.ZIndex="10" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0,0,20,20" Height="23" Width="100" ValueChanged="sldZoom_ValueChanged"/>
Code-behind:
(method of Rectangle (MouseEnter event) dynamically added to grid)
private void rect_MouseEnter(object sender, MouseEventArgs e)
{
RectToolTip = new TextBlock();
RectToolTip.HorizontalAlignment = HorizontalAlignment.Left;
RectToolTip.VerticalAlignment = VerticalAlignment.Top;
RectToolTip.TextAlignment = TextAlignment.Center;
RectToolTip.Height = this.HeaderTwoHeight + 1;
RectToolTip.Text = " " + (RectsTasks[(sender as Rectangle)]).Info + " ";
RectToolTip.Background = this.ToolTipBackground;
RectToolTip.Foreground = this.ToolTipFontColor;
RectToolTipBorder = new Border();
RectToolTipBorder.Child = RectToolTip;
RectToolTipBorder.BorderThickness = new Thickness(this.ToolTipBorderThickness);
RectToolTipBorder.BorderBrush = this.ToolTipBorderColor;
RectToolTipBorder.Margin = new Thickness(e.GetPosition((graphGrid)).X + 10, e.GetPosition((graphGrid)).Y + 10, 0, 0);
RectToolTipBorder.VerticalAlignment = System.Windows.VerticalAlignment.Top;
RectToolTipBorder.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
graphGrid.Children.Add(RectToolTipBorder);
RectToolTipBorder.LayoutTransform = RectToolTip.LayoutTransform = new ScaleTransform(????);
Grid.SetZIndex(RectToolTip, 20);
Grid.SetZIndex(RectToolTipBorder, 20);
}

You need to assign the inverse transform to the child element, so that the child will stay intact.
RectToolTipBorder.LayoutTransform = graphGrid.LayoutTransform.Inverse as Transform;
