Getting started

Adorners

Most adorners are accessible via some attached properties of the class Thinktecture.UIAnnotations.Annotations.
The following sample attaches a watermark (or CueBanner) text to a TextBox.

<TextBox xmlns:uia="clr-namespace:Thinktecture.UIAnnotations;assembly=Thinktecture.UIAnnotations"
    uia:Annotations.CueBanner="Enter your name!"

At runtime it looks like that:

Behaviors

With thinktecture UIAnnotations you can attach Adorners and Behaviors via Markup. There are two models for that:
  • the default behavior declaration using the System.Windows.Interactivity.Interaction class
  • via an attached property of the Thinktecture.UIAnnotations.Behaviors.BehaviorFactory class
Here is a sample that shows the declaration of the Thinktecture.UIAnnotations.Behaviors.OpenFileBehavior via the Interaction class.

<Window 
  xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
  xmlns:uia="clr-namespace:Thinktecture.UIAnnotations; assembly=Thinktecture.UIAnnotations" ...>
  ...
  <Button >
    <i:Interaction.Triggers>
      <i:EventTrigger EventName="Click">
        <!--shows the file open dialog and outputs the selected file to a textbox-->
        <behaviors:OpenFileBehavior
          TargetName="imageTextBox"
          DialogTitle="Select an image..."
          Filter="PNG Files|*.png" />
      </i:EventTrigger>
    </i:Interaction.Triggers>
  </Button>
  <TextBox x:Name="imageTextBox" />
  ...
</Window>

Alternatively,you can set the behavior via the BehaviorFactory class. This is usefull if you want to assign a behavior via style.

<Window xmlns:behaviors="clr-namespace:Thinktecture.UIAnnotations.Behaviors; assembly=Thinktecture.UIAnnotations" ...>
  <Window.Resources>
    <Style TargetType="TextBox">
        <!--assign behavior in a style via BehaviorFactory-->
       <Setter Property="behaviors:BehaviorFactory.BehaviorTypeName"
                     Value="Thinktecture.UIAnnotations.Behaviors.FocusBehavior" />
   </Style>
  </Window.Resources>
</Window>
