The RadioButton control, sometimes referred to as an option button, is similar to the CheckBox control, except it constrains the selection within the range of controls to only one option. So, if you want to present the user with a list of items and want to constrain them to only one choice, you could use a list with the single selection type or a group of RadioButton controls. An additional difference from the CheckBox control is that when a user clicks the radio button when it is selected, the selection will not clear. The only way to clear a selection is to click another RadioButton control. Figure 6-15 shows an example of the RadioButton control in action.

You use the <RadioButton> tag in XAML to specify the use of a RadioButton control. When you use RadioButton controls together within a panel, they form an option group where only one item may be selected. Here s an example: <StackPanel> <RadioButton <RadioButton <RadioButton <RadioButton </StackPanel> Name="radioButton1">USA</RadioButton> Name="radioButton2">Japan</RadioButton> Name="radioButton3">Brazil</RadioButton> Name="radioButton4">Germany</RadioButton>

You can have multiple groups within the same panel by specifying the group name. Thus, you can have a single visible group of RadioButton controls and multiple selectable subgroups. This may sound confusing, so consider the following code: <StackPanel Margin="30,30,30,30"> <RadioButton GroupName="Jerseys"> Blue Jerseys</RadioButton> <RadioButton GroupName="Jerseys"> White Jerseys</RadioButton> <RadioButton GroupName="Shorts"> Red Shorts</RadioButton> <RadioButton GroupName="Shorts"> White Shorts</RadioButton> </StackPanel> This specifies two groups of options: one for Jersey colors and one for Shorts colors. The user can select one option from each range despite that all four RadioButton controls are in the same StackPanel. You can see this in action in Figure 6-16.

Using Complex RadioButton Types
With the RadioButton control, you aren t limited to simple text selections as in the previous sections. The RadioButton control is a content control, allowing you to specify either a single control or a panel (which can contain multiple controls) as its child. Here s an example of a RadioButton selection list that allows you to select from a number of images. The images are

stored in a DockPanel, which contains a StackPanel for each image, and this StackPanel contains the image and the text block containing the label for that image. Listing 6-10 shows an example. Listing 6-10. Complex RadioButtons in XAML <StackPanel> <RadioButton> <StackPanel Orientation="Horizontal"> <Image Source="fishtn.jpg" ></Image> <TextBlock FontSize="24" Height="35" Width="133.19"> Tropical Fish</TextBlock> </StackPanel> </RadioButton> <RadioButton> <StackPanel Orientation="Horizontal"> <Image Source="archtn.jpg" ></Image> <TextBlock FontSize="24" Height="35" Width="133.19"> Pretty Arch</TextBlock> </StackPanel> </RadioButton> <RadioButton> <StackPanel Orientation="Horizontal"> <Image Source="lilytn.jpg" Height="192.5" Width="256"></Image> <TextBlock FontSize="24" Height="35" Width="133.19"> Water Lilies</TextBlock> </StackPanel> </RadioButton> </StackPanel> Figure 6-17 shows this in action. You now have a RadioButton selection group where you can pick one image from the range.

Handling RadioButton Events
When the user selects a RadioButton control, the Click event fires. Thus, you can use the Click attribute on the RadioButton control to specify the function to call as the event handler when this happens. You can add an event handler for each object simply by specifying a function with a different name for each one, so if you have the following (within a container such as a StackPanel so they don t appear on top of each other): <RadioButton Name="rb1" Click="rb1_Click">Item 1</RadioButton> <RadioButton Name="rb2" Click="rb2_Click">Item 1</RadioButton> <RadioButton Name="rb3" Click="rb3_Click">Item 1</RadioButton>
CHAPTER 6 WORKING WITH XAML CONTROLS
you would need three event handler functions, with each looking something like this: void rb1_Click(object sender, RoutedEventArgs e) { rb1.Content = "You Selected Me!"; } Alternatively, you can map all three to the same event handler and use the object sender parameter to work with the source RadioButton control. So, the previous XAML would change to this: <RadioButton Name="rb1" Click="rb_Click">Item 1</RadioButton> <RadioButton Name="rb2" Click="rb_Click">Item 1</RadioButton> <RadioButton Name="rb3" Click="rb_Click">Item 1</RadioButton> This would require only one event handler function, like this: void rb_Click(object sender, RoutedEventArgs e) { System.Windows.Controls.RadioButton b = (sender as System.Windows.Controls.RadioButton); b.Content = "You Selected Me!"; }
