This article describes how to create and use the checkbox control in WPF using XAML.
CheckBox control
CheckBox control enables the user to select and deselect the associated option. When a checkbox is selected a check (a tick mark) appears indicating a selection.
Creating CheckBox control in XAML
<CheckBox Content="CheckBox" Height="16" HorizontalAlignment="Left" Margin="10,10,0,0" Name="checkBox1" VerticalAlignment="Top" />
The Width and Height property represents the width and the height of the control. Name property represents name of the control. The Header property of TabControl represents the header text of the header.
