You can apply a property to a form element in this way:
Let it be Toolbar.
<ElementFilter ElementName="Window">
<StyleSheet>
<ElementIdFilter Identifier="W1">
<StyleSheet>
<ChildFilter>
<StyleSheet>
<ElementFilter ElementName="Toolbar">
<StyleSheet>
<ElementIdFilter Identifier="Tool Bar">
<StyleSheet />
</ElementIdFilter>
</StyleSheet>
</ElementFilter>
</StyleSheet>
</ChildFilter>
</StyleSheet>
</ElementIdFilter>
</StyleSheet>
</ElementFilter>
A property to a specific form element can also be applied using the With ID... filter.
Step
1. Select
'Button'
object form the Elements group, place it onto the Styles
view.
Step
2. Select
the 'With ID ...' filter
from the Diagram section, place it within the Button
object on the Styles view.
Select
the Fore Color → New
Custom Color and drag it into the With ID... object.
Choose the color. As a result the specified Fore color will only be applied to the button with ID 'f005':
<ElementFilter ElementName="Button">
<StyleSheet>
<ElementIdFilter Identifier="f005">
<StyleSheet>
<DoStyleAction>
<SetProperty>
<PropertyPath>
<PropertyName>ForeColor</PropertyName>
</PropertyPath>
<PropertyValue type="CustomizedColor" RedColor="0" GreenColor="128" BlueColor="0" Alpha="255" />
</SetProperty>
</DoStyleAction>
</StyleSheet>
</ElementIdFilter>
</StyleSheet>
</ElementFilter>
