.NET MAUI Scheduler Header Styling

The .NET MAUI Scheduler component comes with built-in styling options that allow you to customize the appearance of its header.

You can style separately the header border, header labels, navigation buttons and more. Here is a list of the available header style properties of the Scheduler:

• HeaderBorderStyle—Applies styles such as border thickness and color to the header.
• HeaderLabelStyle—Applies styles such as TextColor, FontSize, etc to the label displaying the visible range in the header.
• IncreaseVisibleRangeButtonStyle and DecreaseVisibleRangeButtonStyle—Apply styles to the buttons used for navigating the view (only desktop).
• TodayButtonStyle—Defines style for the Today button.
• HeaderIndicatorLabelStyle—Sets style to the label used for showing the popup for date selection (mobile only).
• ViewDefinitionHeaderItemStyle and ActiveViewDefinitionHeaderItemStyle—Apply styles to the available views and active view headers.

The following example demonstrates how to apply custom header styles to the Scheduler:

1. Define the Scheduler:

<telerik:RadScheduler x:Name="scheduler"
                      HeaderBorderStyle="{StaticResource HeaderBorderStyle}"
                      HeaderLabelStyle="{StaticResource HeaderLabelStyle}"
                      IncreaseVisibleRangeButtonStyle="{StaticResource IncreaseVisibleRangeButtonStyle}"
                      DecreaseVisibleRangeButtonStyle="{StaticResource DecreaseVisibleRangeButtonStyle}"
                      TodayButtonStyle="{StaticResource TodayButtonStyle}"
                      HeaderIndicatorLabelStyle="{StaticResource HeaderIndicatorLabelStyle}"
                      ViewDefinitionHeaderItemStyle="{StaticResource ViewDefinitionHeaderItemStyle}"
                      ActiveViewDefinitionHeaderItemStyle="{StaticResource ActiveViewDefinitionHeaderItemStyle}"
                      ActiveViewDefinitionIndex="1">
    <telerik:RadScheduler.ViewDefinitions>
        <telerik:DayViewDefinition />
        <telerik:WeekViewDefinition />
        <telerik:MonthViewDefinition />
    </telerik:RadScheduler.ViewDefinitions>
</telerik:RadScheduler>

2. Add the custom styles to the page's resources:
