31. RichTextBox
control has a similar appearance to a standard TextBox. However, where TextBoxes only permit you to edit plain
text, RichTextBoxes allow you to create complex documents with font and paragraph formatting, page layout
options and inserted elements, such as images.
34. RadioButton Groups
• To group a set of RadioButton controls, you set the GroupName property to
a string value. All of the radio buttons with the same group name are linked but
are not connected to controls in other groups.
<RadioButton Grid.Row="0" GroupName="Handed">Left Handed</RadioButton>
<RadioButton Grid.Row="1" GroupName="Handed" IsChecked="True">Right Handed</RadioButton>
<RadioButton Grid.Row="2" GroupName="Speed" IsChecked="True">Fast Double-Click</RadioButton>
<RadioButton Grid.Row="3" GroupName="Speed">Slow Double-Click</RadioButton>
