Blend 2015
What’s new
Pre Blend 2015
• Blend is a tool for creating great user experiences, with deep
focus on best-in-class UI design capabilities.
• Visual Studio is a tool for creating great apps, with focus on
best-in-class code editing and debugging capabilities.
• Supports
• WPF, Silverlight (Phone), Windows 8 & 8.1
Feedback themes
• No XAML or C# IntelliSense
• File reload experiences when switching between VS and Blend
• Inconsistent shell & project system experiences with VS
• Git and TFS
• Expand/collapse of project nodes
• Performance and scalability of large solutions
Blend for Visual Studio 2015
• Adds Windows 10 support
• Rebuilt from the ground up using VS technologies
• IntelliSense, GoTo Definition, Peek, Debugging, Window Layouts,
Reloading, Customizing
• Retains almost all of the unique Blend capabilities
• SketchFlow is killed
Blend 2015
UI Debugging for XAML
• Visual tree inspection and manipulation
• Live tracking of tree and property changes
• Fully integrated into debugging
• Upcoming
• Serializing edits back into source
• Edit-n-continue
• Data debugging visualizations
Live Visual Tree
Layout Controls
Panels
Layout Controls• Canvas
• Simplest, placement relative to the top left edge
• Not scalable
• StackPanel
• Horizontal or vertical stacking
• RelativePanel
• You arrange child elements by specifying how they should be arranged in relationships to
each other, and how they should position relative to their content and/or their parent
• Grid
• Uses rows and columns
• Flexible Positioning (similar to <TABLE /> in HTML)
• More
• Border (“Obsolete”), ScrollViewer, Viewbox, VariableSizedWrapGrid
Canvas
• Is a Drawing Surface
• Children have fixed positions relative to top-left-corner
<Canvas Width="250" Height="200" Background="Gray">
<Rectangle Canvas.Top="25" Canvas.Left="25" Width="200" Height="150" Fill="Yellow" />
</Canvas>
The Canvas
The Rectangle
XAML - Attached Properties
• Top & Left properties only make sense inside a Canvas
<Canvas Width="250" Height="200" Background="Gray">
<Rectangle Canvas.Top="25" Canvas.Left="25" Width="200" Height="150" Fill="Yellow" />
</Canvas>
StackPanel
• The StackPanel will place its children in either a column
(default) or row. This is controlled by the Orientation
property.
<StackPanel Orientation="Horizontal"BorderBrush="#FF0B77FD"BorderThickness="2"Padding="5">
<Button Content="Button1" FontSize="30" /><Button Content="Button2" FontSize="30" Margin="5,0" /><Button Content="Button3" FontSize="30" />

Grid
• The Grid is a powerful layout container.
• It acts as a placeholder for visual elements
• You specify the rows and columns, and those define the cells.
• The placement of an element in the Grid is specified using attached properties
that are set on the children of the Grid:
• Supports different types of row and column sizes in one Grid:
• Pixel size: Fixed value in pixels
• Auto size: The cell has the size of it’s contents
• Star size: whatever space is left over from fixed- and auto-sized columns is allocated to all of the columns with star-sizing
<Image Grid.Column="3" Source="demo.png" Stretch="None"/>

Resources
Reusable objects such as data, styles and templates
Resources
• Reusable objects such as data, styles and templates.
• Assigned a unique key (x:Key) so you can reference to it.
• Every element has a Resources property.
• Nesting Support
• All static resources are loaded on page load
• Resource is loaded even if not used
45
Convert to New Resource…
Resources in Blend
• Menu Window - Resources
• Shows all resources of all open XAML documents
• Link to Resource Dictionary
• Edit Resource
• Rename Resource
• Move Resource
• Delete Resource
• Apply Resource by Drag & Drop

Windows 10 - SystemAccentColor
• Reduces the need for a custom Theme
Animations & Behaviors
Storyboards & Transitions
Interactivity without Code
Key Frame Concept
• XAML supports key frames
• A key frame defines an objects target value on a moment in
an animation.
• A key frame has an interpolation method.
• A Key Frame target can be a:
• Double (X, Y, Height, Width, Opacity, Angle, etc.)
• Color (Fill, Stroke, etc.)
• Object (Visibility, Text, etc)
Storyboards
51
Record Storyboard animations
Storyboards
• The Storyboard object has interactive methods to Begin, Pause, Resume, and Stop an animation.
public void ButtonStart_Click(object sender, MouseEventArgs e) {if (myStoryboard.GetCurrentState() == ClockState.Stopped) {
myStoryboard.Begin();}
}
public void ButtonPause_Click(object sender, MouseEventArgs e) {myStoryboard.Pause();
}
public void ButtonResume_Click(object sender, MouseEventArgs e) {myStoryboard.Resume();
}
public void ButtonStop_Click(object sender, MouseEventArgs e) {myStoryboard.Stop();
}

Styling and Templating
Customize the look of an application without changing
it’s behavior
Styling and Templating
• Styling = Small Visual Changes on an Element (Font,
Background Color, etc.)
• Templating = Replacing Element’s entire Visual Tree
Styling
<Page.Resources><Style x:Key="HollandButtonStyle" TargetType="Button">
<Setter Property="Background" Value="#FFFF9E00"/><Setter Property="FontSize" Value="40"/><Setter Property="FontStyle" Value="Italic"/>
</Style></Page.Resources>
<Grid><Button Content="Button"
Style="{StaticResource HollandButtonStyle}"/></Grid>
Implicit Styling
• If you omit the Style’s Key and specify only the TargetType, then the Style is automatically applied to all elements of that target type within the same scope (it is implicitly applied).
• This is typically called a typed style as opposed to a named style.
<Style TargetType="TextBox"><Setter Property="FontFamily" Value="Arial Black"/><Setter Property="FontSize" Value="16"/>
</Style>
BasedOn Styling<Page.Resources>
<Style x:Key="HollandButtonStyle" TargetType="Button"><Setter Property="Background" Value="#FFFF9E00"/><Setter Property="FontSize" Value="24"/><Setter Property="FontStyle" Value="Italic"/>
</Style><Style x:Key="GermanButtonStyle"
TargetType="Button"BasedOn="{StaticResource HollandButtonStyle}">
<Setter Property="Background" Value="White"/><Setter Property="Foreground" Value="Black"/><Setter Property="BorderBrush" Value="Black"/>
</Style></Page.Resources>
<Grid><Button Content="Button"
Style="{StaticResource GermanButtonStyle}"/><Button Content="Button"
Style="{StaticResource HollandButtonStyle}"/></Grid>
Templating - CombinedStates
DataBinding
Data Binding
• Data binding is the process that establishes a connection, or binding,
between the UI and the business object which allows data to flow
between the two
• Enable clean view/model separation and binding• Change UI presentation without code-behind modifications
• Every binding has a source and a target• Source is the business object or another UI element
• Target is the UI element
• Binding Expressions can be one way or two way and supports
converters
Element to Element Binding
• Element binding is performed in the same manner as Data Binding with one addition: the ElementName property. ElementName defines the name of the binding source element.
<RelativePanel HorizontalAlignment="Center"VerticalAlignment="Center">
<TextBlock Text="{Binding ElementName=mySlider, Path=Value}"RelativePanel.RightOf="mySlider"FontSize="32" Margin="20,0,0,0" />
<Slider x:Name="mySlider"Maximum="10"Value="6"Width="400" />
</RelativePanel>
Compiled Binding {x:Bind}
• DataBind to a Property or Field of the Code Behind
• Databinding code is generated in the .g.cs file
• Up to 5x faster
• Default Mode = OneTime !!!
• Not tooling support yet!
• Use IntelliSense
<TextBlock Text="{x:Bind mySlider.Value, Mode=OneWay}"RelativePanel.LeftOf=""RelativePanel.RightOf="mySlider"FontSize="32"Margin="20,0,0,0" />
