The ToolTipService class is used to programmatically associate a UIElement describing content of the tool tip with the control. It provides an attached property (ToolTip) that is used in the XAML to create a tool tip without having to go to the code-behind. Figure 3-25 shows two buttons, the first with a tool tip already attached (displayed in the figure), and the second that gets a tool tip after the first button is clicked.

<Button Canvas.Left="20" Canvas.Top="40" ToolTipService.ToolTip="Click button to add a tooltip to the other button" Content="I have a tooltip!" Click="Button_Click"/> The click handler programmatically adds the second button s tool tip via the SetTooltip method. private void Button_Click(object sender, RoutedEventArgs e) { Border b = new Border(); b.BorderBrush = new SolidColorBrush(Color.FromArgb(255, 128, 128, 128)); b.BorderThickness = new Thickness(5); TextBlock t = new TextBlock(); t.Margin = new Thickness(5); t.Text = "I am another tool tip"; b.Child = t; ToolTipService.SetToolTip(secondButton, b); } To set the tooltip using the code-behind, the ToolTipService class provides several key static methods (Table 3.38) to set the tooltip for the UIElement and define the placement.

GetPlacementTarget Returns the UIElement for which the tooltip is set. GetToolTip SetPlacement Returns the value of the tooltip. Sets position of the tooltip relative to the target UIElement using the specified placement mode. The position is based on the value of the PlacementMode. The possible values are Bottom (bottom of the target element), Right (right of the target element), Mouse (current mouse pointer location), Left (Left of the target element), and Top (top of the target element).

ScrollViewer
The ScrollViewer control is used to display content that is possibly larger than the allotted space, so scrollbars are used to let the user scroll to different sections of the content. It exposes a large set of properties that control the presentation of content, shown in Table 3-39.

Figure 3-26 shows a grid with a checkerboard pattern contained in a ScrollView control. The content is too large to display completely, so the vertical scrollbar is added automatically (the horizontal scrollbar is added automatically but must be set to Auto first).
Figure 3-26. The ScrollViewer control example Here s the XAML to create the grid inside the scroll viewer:
SILVERLIGHT USER INTERFACE CONTROLS
<Canvas x:Name="LayoutRoot" Background="White"> <ScrollViewer Canvas.Left="60" Canvas.Top="70" Width="250" Height="200" HorizontalScrollBarVisibility="Auto"> <Grid Background="White" Height="300" Width="400"> <!-- 3 rows, 3 columns --> <!-- Border controls to draw a different background in each cell --> </Grid> </ScrollViewer> </Canvas>
The RangeBase Class
The RangeBase class provides behavior to handle a range of values and a selected value within this range. It is the base class of the ScrollBar, Slider, and ProgressBar controls. The RangeBase class uses value coercion in order to ensure the current value is within the range (i.e., the value remains between or equal to the minimum and maximum defined values). An ArgumentException will be raised if any of the properties defining the end points of the range are set to a value that does not make sense, such as setting Minimum to NaN or SmallChange to a value less than zero. Table 3-40 shows the properties of RangeBase. Table 3-40. Properties of the System.Windows.Controls.Primitives.RangeBase Class
