ListView Scroll whole layout/page

How can I make the ListView/Layout scroller to behave like modern layout like in android or windows 10. Currently the ListView scrollbar only applies to the ListView itself. I want the scroller to scroll the whole layout including the search bar in XAML.
I want also the ListView Items added to increment to the overall height of the ListView to achieve the effect.
Any available ways to do it with Native wpf xaml (No frameworks/dlls, just pure xaml/c#)

Put your ListView, search bar, and whatever else you want to scroll inside of a ScrollViewer.

Why is my image becoming pixelated during runtime?

So whenever I am working with the application in the design window and I am zoomed in, the image is not blurry at all
However as soon as I run the application it looks like this.
It gets very pixelated and I have no idea why.
Here is the XAML code for the button
<Button Margin="10,0,0,0" Style="{DynamicResource RoundedButtonStyle}" Width="100" Height="30" HorizontalAlignment="Left">
<Grid>
<Image UseLayoutRounding="True" IsHitTestVisible="False" Height="20" Width="20" VerticalAlignment="Center" HorizontalAlignment="Left" Source="Resources/addButton.png" />
<TextBlock IsHitTestVisible="False" Margin="20,0,0,1" VerticalAlignment="Center" Foreground="#9e9e9e">Add Product</TextBlock>
</Grid>
</Button>
And the Template
<Setter Property="Background" Value="#2d2d30"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border CornerRadius="5" Background="{TemplateBinding Background}" BorderThickness="1" Padding="2">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#686868"/>
</Trigger>
</Style.Triggers>
</Style>
And the original image that I am using.

You shouldn't be using a bitmap icon at all.
Either use a symbol from a font
<Button Width="100" Height="30">
<StackPanel Orientation="Horizontal">
<TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text=""/>
<TextBlock VerticalAlignment="Center" Text=" Add Product"/>
</StackPanel>
</Button>
or a Path with a vector drawing:
<Button Width="100" Height="30">
<StackPanel Orientation="Horizontal">
<Path Stroke="Black" StrokeThickness="1.5"
StrokeStartLineCap="Round" StrokeEndLineCap="Round">
<Path.Data>
<GeometryGroup>
<EllipseGeometry Center="9,9" RadiusX="9" RadiusY="9"/>
<LineGeometry StartPoint="5,9" EndPoint="13,9"/>
<LineGeometry StartPoint="9,5" EndPoint="9,13"/>
</GeometryGroup>
</Path.Data>
</Path>
<TextBlock VerticalAlignment="Center" Text=" Add Product"/>
</StackPanel>
</Button>

I think you should try out different RenderOptions.BitmapScalingModes (as mentioned here)
<Button Margin="10,0,0,0" Style="{DynamicResource RoundedButtonStyle}" Width="100" Height="30" HorizontalAlignment="Left">
<Grid>
<Image UseLayoutRounding="True" IsHitTestVisible="False" Height="20" Width="20" VerticalAlignment="Center" HorizontalAlignment="Left" Source="Resources/addButton.png"
RenderOptions.BitmapScalingMode="Fant"
/>
<TextBlock IsHitTestVisible="False" Margin="20,0,0,1" VerticalAlignment="Center" Foreground="#9e9e9e">Add Product</TextBlock>
</Grid>
</Button>
For images with low color count (like in your case), NearestNeighbour works the best.

In the XAML the Height and the Width of the image are set to 20 and the size of the original image is 128 by 128. So WPF has to scale the image down quite a bit. That will result in a pixelated/rough image (especially with round shapes)
Solution: recreate the image in its correct size (20x20).

DataGrid with resizable height

I have a DataGrid wrapped in a Grid<-StackPanel and my problem is when I resize the window, DataGrid won't stretch and it's just adding blank space at the end.
I have tried binding and VerticalAlignment="Stretch" but to luck.

If you put a control inside a StackPanel it will be take only the space it need to be visualised, so it will not stretch.
For a dynamic view I almost always use a grid with row and column definitions.

c# wpf binding not working with datacontexts

I wish to display a ToolTip for an entry in a Listbox.
The Toolkit will contain a Textbox and a copy (larger) of the Image in the entry in the Listbox
I can get either the Text in the Textbox Or the Image to display.
The code which displays the image but not the text is
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" SnapsToDevicePixels="true" Background="#EEFFFFFF" BorderBrush="#FFCCCCCC"
HorizontalAlignment="Center" VerticalAlignment="Center"
BorderThickness="1">
<Grid>
<StackPanel Margin="0,0,0,0" VerticalAlignment="Top" HorizontalAlignment="Left">
<Image x:Name="img" ToolTipService.Placement="Top"
Source="{Binding Path=ImageUri}" Height="64" Stretch="Uniform" Width="64">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleX="1" ScaleY="1" x:Name="scaleTrans"/>
</TransformGroup>
</Image.RenderTransform>
<Image.ToolTip>
<ToolTip BorderBrush="{x:Null}" Background="{x:Null}" Effect="{x:Null}"
DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}"
HasDropShadow="False">
<Border Background="{x:Null}" VerticalAlignment="Center" Margin="0" Width="600"
HorizontalAlignment="Center">
<Grid Background="{x:Null}">
<StackPanel >
<TextBlock Margin="5" Padding="5" FontSize="14" FontWeight="Bold"
Text="{Binding Path=FTitle}"
Background="{DynamicResource {x:Static SystemColors.InactiveBorderBrushKey}}"/>
<Border Margin="8,0,8,12.5" VerticalAlignment="top">
<Image Source="{Binding Path=Source}"/>
</Border>
</StackPanel>
</Grid>
</Border>
</ToolTip>
</Image.ToolTip>
</Image>
</StackPanel>
</Grid>
</Border>
</ControlTemplate>
This code is part of the code for which is used by a ListBox
The code below (as in the list above display the Image in the tooltip but not the Textbox
<ToolTip BorderBrush="{x:Null}" Background="{x:Null}" Effect="{x:Null}"
DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}"
HasDropShadow="False">
<Border Background="{x:Null}" VerticalAlignment="Center"Margin="0" Width="600"
HorizontalAlignment="Center">
<Grid Background="{x:Null}">
<StackPanel >
<TextBlock Margin="5" Padding="5" FontSize="14" FontWeight="Bold"
Text="{Binding Path=FTitle}"
Background="{DynamicResource {x:Static SystemColors.InactiveBorderBrushKey}}"/>
<Border Margin="8,0,8,12.5" VerticalAlignment="top">
<Image Source="{Binding Path=Source}"/>
</Border>
</StackPanel>
</Grid>
</Border>
</ToolTip>
If you remove
DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}" from <ToolTip
The Text works as expected but the Image now fails (as expected)
I have tried to
a) modify the original so the TextBlock binding point to the FTitle entry observable Collection driving the listbox entries
<TextBlock Margin="5" Padding="5" FontSize="14" FontWeight="Bold"
Text="{Binding Path=DataContext.FTitle, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"
Background="{DynamicResource {x:Static SystemColors.InactiveBorderBrushKey}}"/>
b) moved the datacontext in to Image
<Border Margin="8,0,8,12.5" VerticalAlignment="top">
<Image Source="{Binding Path=DataContext.Source, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Image}}}"/>
</Border>enter code here
Neither worked. (I did try many variations But none worked.
I would be grateful for either solution

{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}} will bind the UIElement (a ListBoxItem) as the DataContext for the tooltip. It seems you want the DataContext of the ListBoxItem in order to bind to properties of the underlying model. In which case, try changing your DataContext binding to be: {Binding Path=PlacementTarget.DataContext, RelativeSource={x:Static RelativeSource.Self}}

WPF Itemcontrol datatemplate

I'm new in WPF and I can not work this one out hope you guys could help on this. The problem is that the DesignerItemTemplate is not working when its in the item control, I have try to use this directly to one item I can drag it around. Forgive me if the code look messy. Thanks in advance

If this doesn't help, could you please provide a little simpler example which demonstrates the problem and describe what you want to achive. It's not clear to me what you want to achive.

I found the problem! It was the InspectionItemList collection object that inheriting to a observable object. when I removed the obeservable in the object it works perfectly. Thanks Clemens and Stackoverflow this site really helps me a lot.
