The following code shows how to change the styles of labels for individual layout items, or all of them. The style is changed via the LayoutItem.LabelStyle property. Styles of layout items’ labels can be customized via the LayoutItem.LabelStyle property. This example demonstrates two approaches to changing the LabelStyle property:

for all layout items belonging to a container - via the container’s LayoutGroup.ItemStyle property. In this example, this style specifies the blue foreground color for labels
for individual layout items - directly via their LayoutItem.LabelStyle properties. In the example, this style, applied to the first layout item (Model), paints the item’s label in red.

The following image shows the result:
