Create a CheckEdit

XAML

<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.

Xaml

<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.

XAML

<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.

XAML

<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.

CheckEdit Colors

Use the following properties to specify CheckEdit element colors:

Element	Property
Glyph	CheckEditGlyphBrush
Background when the editor is checked	CheckedStateBackground
BorderBrush when the editor is checked	CheckedStateBorderBrush
BorderBrush when the editor is focused	FocusedBorderBrush

Standard Appearance Customization Properties

BorderThickness	Gets or sets the border thickness of a control.
CornerRadius	Gets or sets the editor’s corner radius. This is a dependency property.

Optimized for In-Place Editing

CheckEdit can be used as a standalone or in-place editor nested in a container control. The CheckEditSettings class implements the in-place editing functionality. Refer to the Assign Editors to Cells topic for more information.
