Namespace: DevExpress.Xpf.Docking

Assembly: DevExpress.Xpf.Docking.v22.2.dll

NuGet Package: DevExpress.Wpf.Docking

Declaration

    FixedItem

Remarks

Unlike the Margin property, an EmptySpaceItem object is not bound to a specific UI element.

The following code sample adds EmptySpaceItem to the application’s layout:

<Window ...
    xmlns:dxdo="http://schemas.devexpress.com/winfx/2008/xaml/docking">
    <Grid>
        <dxdo:DockLayoutManager>
            <dxdo:LayoutGroup>
                <dxdo:LayoutGroup Orientation="Vertical">
                    <dxdo:LayoutGroup>
                        <dxdo:LabelItem Caption="First Name"/>
                        <dxdo:LayoutControlItem>
                            <TextBox Text="Arnold"/>
                        </dxdo:LayoutControlItem>
                    </dxdo:LayoutGroup>
                    <dxdo:LayoutGroup>

                            <TextBox Text="Schwartz"/>
                        </dxdo:LayoutControlItem>
