How to customize .NET MAUI Scheduler Days View?
The .NET MAUI Scheduler allows customization of the days view header in the day, week, workweek, month, and timeline views through the ViewHeaderTemplate property of the DaysView, TimelineView, and MonthView.
The BindingContext of the ViewHeaderTemplate is System.DateTime.
STEP 1:
Define a DataTemplate to customize the appearance of the timeline view header.
<DataTemplate x:Key="timelineViewHeaderTemplate">
<Grid x:Name="grid" Background="MediumPurple" >
<Label x:Name="label" HorizontalOptions="Start" VerticalOptions="Center" TextColor="White" >
<Label.Text>
<MultiBinding StringFormat = "{}{0:dd} {1:ddd}" >
<Binding />
<Binding />
</MultiBinding >
</Label.Text >
<Label.Triggers >
<DataTrigger TargetType="Label" Binding="{Binding}" Value="{x:Static system:DateTime.Today}">
<Setter TargetName = "label" Property="TextColor" Value="Orange"/>
</DataTrigger>
</Label.Triggers>
</Label>
<Grid.Triggers>
<DataTrigger TargetType = "Grid" Binding="{Binding}" Value="{x:Static system:DateTime.Today}">
<Setter TargetName = "grid" Property="Background" Value="LightGreen"/>
</DataTrigger>
</Grid.Triggers>
</Grid>
</DataTemplate>
STEP 2:
Define another DataTemplate for the day, week, workweek, and month view header.
<DataTemplate x:Key="viewHeaderTemplate">
<StackLayout x:Name="stackLayout" Orientation="Vertical" Background="MediumPurple">
<Label x:Name="label" HorizontalOptions="Center" VerticalOptions="Center" Text="{Binding StringFormat='{0:dd}'}" FontSize="Small" FontFamily="Bold" TextColor="White" >
<Label.Triggers>
<DataTrigger TargetType = "Label" Binding="{Binding}" Value="{x:Static system:DateTime.Today}">
<Setter TargetName = "label" Property="TextColor" Value="Orange"/>
</DataTrigger>
</Label.Triggers>
</Label>
<Label x:Name="label1" HorizontalOptions="Center" VerticalOptions="Center" Text="{Binding StringFormat='{0:ddd}'}" FontSize="Small" FontFamily="Bold" TextColor="White">
<Label.Triggers>
<DataTrigger TargetType = "Label" Binding="{Binding}" Value="{x:Static system:DateTime.Today}">
<Setter TargetName = "label1" Property="TextColor" Value="Orange"/>
</DataTrigger>
</Label.Triggers>
</Label>
<StackLayout.Triggers>
<DataTrigger TargetType = "StackLayout" Binding="{Binding}" Value="{x:Static system:DateTime.Today}">
<Setter TargetName = "stackLayout" Property="Background" Value="MediumPurple"/>
</DataTrigger>
</StackLayout.Triggers>
</StackLayout>
</DataTemplate>
STEP 3:
Assign the templates to appropriate views in the scheduler.
<scheduler:SfScheduler x:Name="Scheduler"
View="Month" AllowedViews="Day,Week,WorkWeek,TimelineDay,TimelineWeek,TimelineWorkWeek, TimelineMonth">
<scheduler:SfScheduler.DaysView>
<scheduler:SchedulerDaysView ViewHeaderTemplate="{StaticResource viewHeaderTemplate}"
/>
</scheduler:SfScheduler.DaysView>
<scheduler:SfScheduler.TimelineView>
<scheduler:SchedulerTimelineView ViewHeaderTemplate="{StaticResource timelineViewHeaderTemplate}"/>
</scheduler:SfScheduler.TimelineView>
<scheduler:SfScheduler.MonthView>
<scheduler:SchedulerMonthView ViewHeaderTemplate="{StaticResource viewHeaderTemplate}"/>
</scheduler:SfScheduler.MonthView>
</scheduler:SfScheduler>Download the complete sample on GitHub
