Create a CheckEdit
<Window ...
xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors">
<!-- Specify a value using the CheckEdit.IsChecked property -->
<dxe:CheckEdit IsChecked="True" />
<!-- Specify a value using the BaseEdit.EditValue property -->
<dxe:CheckEdit EditValue="False" />
Editor Value
Use the CheckEdit.IsChecked property to specify the editor’s state. To set the editor to the indeterminate state (if supported), set the CheckEdit.IsChecked property to null.
After the CheckEdit.IsChecked property’s value has been changed, the check editor fires the corresponding event (CheckEdit.Checked, CheckEdit.Unchecked or CheckEdit.Indeterminate).
Optional Indeterminate State
If you set the CheckEdit.IsThreeState property to true, the CheckEdit control can hold a null value. This is called the Indeterminate state.
<dxe:CheckEdit Content="Checked" IsThreeState="True" IsChecked="True"/>
<dxe:CheckEdit Content="Indeterminate" IsThreeState="True" IsChecked="{x:Null}"/>
<dxe:CheckEdit Content="Unchecked" IsThreeState="True" IsChecked="False"/>
Appearance Customization
Custom Glyphs
To make the CheckEdit
display custom glyphs instead of the standard glyphs, pass the ImageCheckEditStyleSettings object to the CheckEdit‘s StyleSettings property.
Use the CheckedGlyph, IndeterminateGlyph, and UncheckedGlyph properties to specify glyphs for all CheckEdit states.
<dxe:CheckEdit
Content="CheckEdit"
CheckedGlyph="TrafficLightGreen.png"
UncheckedGlyph="TrafficLightRed.png"
IndeterminateGlyph="TrafficLightYellow.png"
IsThreeState="True">
<dxe:CheckEdit.StyleSettings>
<dxe:ImageCheckEditStyleSettings />
</dxe:CheckEdit.StyleSettings>
</dxe:CheckEdit>
The CheckEdit control scales the specified glyphs to 16px. To customize the rendered image size, pass a custom data template to the GlyphTemplate property, as in the code sample below.
<dxe:CheckEdit
Content="CheckEdit"
CheckedGlyph="TrafficLightGreen.png"
UncheckedGlyph="TrafficLightRed.png"
IndeterminateGlyph="TrafficLightYellow.png"
IsThreeState="True">
<dxe:CheckEdit.GlyphTemplate>
<DataTemplate>
<Image Source="{Binding}" Height="32" Width="72"/>
</DataTemplate>
</dxe:CheckEdit.GlyphTemplate>
<dxe:CheckEdit.StyleSettings>
<dxe:ImageCheckEditStyleSettings />
</dxe:CheckEdit.StyleSettings>
</dxe:CheckEdit>
Custom Content
To specify the editor’s content, use the CheckEdit.Content property.
Use the ContentTemplate and ContentTemplateSelector properties to customize the editor’s content appearance.
CheckBox Width/Height
Use the CheckBoxWidth and CheckBoxHeight properties to specify the glyph’s width and height.

Element | Property |
