You can modify interface elements (controls) by changing directly manageable colors – a theme color (ThemeColor) and background color (ThemeBackground) – in the Interface Configuration panel or by adjusting elements globally (all controls of the same type at once) in the Global Elements panel or locally (independently per view) in the Layout Management panel. Changing any control parameter locally is treated with a higher priority than when changing it globally.

Layout.Id

Layout management depends on a number of factors. Primarily, a view must be properly registered (using the RegisterViews method from the ModuleBase class) and a relevant view model for the design mode (DesignViewModel) must be created. It is also necessary to assign an appropriate attribute to controls.

The attribute is Layout.Id and it must be unique within the entire POS application. This is essential to make it possible for a control to be manageable independently. If more than one control has the same ID, changing a property for only one of them will affect them all.

Setting default values for manageable properties

Default control values can be set up in several ways, depending on your needs.

1. Directly, as the attributes of a defined control in the xaml

<TextBlock Foreground="Red"/>

The control above will not be manageable, as the Layout.Id attribute has not been defined for it.

You can also combine this with color schemes and font:

<TextBlock Foreground="{DynamicResource ThemeColor}"/>

The control will only be manageable through the change of a color theme (a font color will be changed).

For a control to be manageable globally in the global interface configuration, it needs to be registered using the RegisterControl method from the ModuleBase class.

For a control to be manageable locally per view where it has been used (layout management), the view must be properly registered (using the RegisterViews method) and the control must have the Layout.Id attribute. When using Layout.Id, default control properties should not be set up directly in the control. If a default value, such as Foreground, is defined before determining Layout.Id, the value will be ignored. In turn, defining Foreground after Layout.Id will make the property unmanageable (it will always be overwritten with the directly set-up value).

Attributes should be set up directly only for unmanageable properties, such as ones that are not required for a control to work properly (e.g., Binding).

2. Control’s global style or local style (using x:Key)

<core:View.Resources>
        <Style TargetType="TextBlock" BasedOn="{StaticResource {x:Type TextBlock}}">
            <Setter Property="Foreground" Value="Red"/>
            <Setter Property="Background" Value="{DynamicResource ThemeBackground}"/>
        </Style>
</core:View.Resources>
..
<TextBlock core:Layout.Id="TextBlockLayoutId" />

The example above illustrates global settings for the style of the font and background color of all TextBlock controls used within the current view <core:View>.

<core:View.Resources>
        <Style x:Key="TextBlockStyle" 
               TargetType="TextBlock" BasedOn="{StaticResource {x:Type TextBlock}}">
            <Setter Property="Foreground" Value="Red"/>
            <Setter Property="Background" Value="{DynamicResource ThemeBackground}"/>
        </Style>
</core:View.Resources>
…
<TextBlock Style="{StaticResource TextBlockStyle}" core:Layout.Id="TextBlockLayoutId" />

The modification above presents how to use styles in order to set up only a selected control.

3. Default attribute defined in ModernUI.xaml according to the definition attribute_type x:Key=”[LayoutId].Default.[type_name]”>[default value]</attribute_type>

ModernUI.xml file

<SolidColorBrush x:Key="TextBlockLayoutId.Default.Foreground" Color="Red"/>

View file

<TextBlock core:Layout.Id="TextBlockLayoutId" />

The prerequisite for the example above to work properly is to register ModernUI.xaml resources of the module in the class registering the module (see the chapter New module in How to create views). In the constructor, it is necessary to call:

LayoutService.RegisterResources(typeof(Module));

This approach involves certain limitations, as it does not allow defining dynamic values and grouping recurrent values under a common name. For instance, it is not correc to use the following code:

<SolidColorBrush x:Key="TextBlockLayoutId.Default.Foreground" 
            Color="{DynamicResource ThemeColor}"/>

In this case, the type Color (System.Windows.Media.Color) and ThemeColor (SolidColorBrush) are incompatible!

Using this method is currently not recommended, except when defining default parameters for DataGrid columns.
