    <!-- Adds a default PopupCalcEdit to your window -->
    <dxe:PopupCalcEdit />
</Window>

Editor Value

The editor's value can be specified using the BaseEdit.EditValue or PopupCalcEdit.Value property.

<Window ...

<!-- Specify value using the BaseEdit.EditValue property -->
<dxe:PopupCalcEdit EditValue="0"/>
