CheckBox Styles and Templates

 

This topic describes the styles and templates for the CheckBox control. You can modify the default ControlTemplate to give the control a unique appearance. For more information, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate.

The CheckBox control does not have any named parts.

The following table lists the visual states for the CheckBox control.

VisualState NameVisualStateGroup NameDescription
NormalCommonStatesThe default state.
MouseOverCommonStatesThe mouse pointer is positioned over the control.
PressedCommonStatesThe control is pressed.
DisabledCommonStatesThe control is disabled.
FocusedFocusStatesThe control has focus.
UnfocusedFocusStatesThe control does not have focus.
CheckedCheckStatesIsChecked is true.
UncheckedCheckStatesIsChecked is false.
IndeterminateCheckStatesIsThreeState is true, and IsChecked is null.
ValidValidationStatesThe control uses the Validation class and the Validation.HasError attached property is false.
InvalidUnfocusedValidationStatesThe Validation.HasError attached property is true has the control has focus.
InvalidFocusedValidationStatesThe Validation.HasError attached property is true has the control does not have focus.

The following example shows how to define a ControlTemplate for the CheckBox control.

  <Style x:Key="{x:Type CheckBox}"
         TargetType="{x:Type CheckBox}">
    <Setter Property="SnapsToDevicePixels"
            Value="true" />
    <Setter Property="OverridesDefaultStyle"
            Value="true" />
    <Setter Property="FocusVisualStyle"
            Value="{DynamicResource CheckBoxFocusVisual}" />
    <Setter Property="Template">
      <Setter.Value>
