19 Oct 202224 minutes to read
This section describes how to select a date range from drop-down calendar and customization options available in Calendar DateRange Picker control.

NOTE
If you change the drop-down alignment by using the
DropDownPlacementproperty and there is not sufficient space, thenCalendar DateRange Pickersmartly shifts the drop-down calendar alignment.
<calendar:SfCalendarDateRangePicker x:Name="sfCalendarDateRangePicker"
DropDownPlacement="Right" />
SfCalendarDateRangePicker sfCalendarDateRangePicker = new SfCalendarDateRangePicker();
sfCalendarDateRangePicker.DropDownPlacement = FlyoutPlacementMode.Right;
Change drop-down size
You can change the size of drop-down calendar in Calendar DateRange Picker by using the DropDownHeight property. The default value of DropDownHeight property is Auto.
NOTE
The drop-down size will be automatically resized based on the calendar and preset items hosted in it.
<calendar:SfCalendarDateRangePicker x:Name="sfCalendarDateRangePicker"
DropDownHeight="500" />
SfCalendarDateRangePicker sfCalendarDateRangePicker = new SfCalendarDateRangePicker();
sfCalendarDateRangePicker.DropDownHeight = 500;
Customize individual items in Calendar
You can change the UI of specific cells in Calendar DateRange Picker drop-down calendar by using the FlyoutBase.AttachedFlyout property and DropDownFlyout control.

Create a EventDataConverter class and set the special dates for specific events.
public class EventDataConverter : IValueConverter { Dictionary<DateTimeOffset, string> SpecialDates; public EventDataConverter() { SpecialDates = new Dictionary<DateTimeOffset, string>(); SpecialDates.Add(DateTimeOffset.Now.AddMonths(-1).AddDays(1), "SingleEvent_1"); SpecialDates.Add(DateTimeOffset.Now.AddMonths(-1).AddDays(5), "DoubleEvent_1"); SpecialDates.Add(DateTimeOffset.Now.AddMonths(-1).AddDays(-2), "TripleEvent_2"); SpecialDates.Add(DateTimeOffset.Now.AddDays(1), "TripleEvent_1"); SpecialDates.Add(DateTimeOffset.Now.AddDays(5), "SingleEvent_2"); SpecialDates.Add(DateTimeOffset.Now.AddDays(7), "DoubleEvent_2"); SpecialDates.Add(DateTimeOffset.Now.AddDays(9), "SingleEvent_1"); SpecialDates.Add(DateTimeOffset.Now.AddDays(12), "TripleEvent_2"); SpecialDates.Add(DateTimeOffset.Now.AddDays(-4), "DoubleEvent_1"); SpecialDates.Add(DateTimeOffset.Now.AddMonths(1).AddDays(1), "DoubleEvent_3"); SpecialDates.Add(DateTimeOffset.Now.AddMonths(1).AddDays(3), "SingleEvent_2"); SpecialDates.Add(DateTimeOffset.Now.AddMonths(1).AddDays(-5), "DoubleEvent_2"); } public object Convert(object value, Type targetType, object parameter, string language) { DateTimeOffset dateTimeOffset = SpecialDates.Keys.FirstOrDefault(x => x.Date == (DateTime)value); if (dateTimeOffset != DateTimeOffset.MinValue) { string template = SpecialDates[dateTimeOffset]; StackPanel stackPanel; switch (template) { case "SingleEvent_1": return new List<Brush>() { new SolidColorBrush(Colors.DeepPink) }; case "SingleEvent_2": return new List<Brush>() { new SolidColorBrush(Colors.Cyan) }; case "DoubleEvent_1": return new List<Brush>() { new SolidColorBrush(Colors.Violet), new SolidColorBrush(Colors.Orange) }; case "DoubleEvent_2": return new List<Brush>() { new SolidColorBrush(Colors.Gold), new SolidColorBrush(Colors.Green) }; case "DoubleEvent_3": return new List<Brush>() { new SolidColorBrush(Colors.Brown), new SolidColorBrush(Colors.Blue) }; case "TripleEvent_1": return new List<Brush>() { new SolidColorBrush(Colors.Green), new SolidColorBrush(Colors.DeepSkyBlue), new SolidColorBrush(Colors.Orange) }; case "TripleEvent_2": return new List<Brush>() { new SolidColorBrush(Colors.Red), new SolidColorBrush(Colors.Green), new SolidColorBrush(Colors.Gold) }; } } return null; } public object ConvertBack(object value, Type targetType, object parameter, string language) { return null; } } -
Create a DataTemplate to customize the date cells of the calendar. Now, add the
Calendarcontrol inside theFlyoutBase.AttachedFlyoutproperty and theDropDownFlyoutcontrol.<Grid> <Grid.Resources> <local:EventDataConverter x:Key="EventDataConverterKey" /> <DataTemplate x:Key="customTemplate"> <ItemsControl ItemsSource="{Binding Path=Date, Converter={StaticResource EventDataConverterKey}}"> <ItemsControl.ItemTemplate> <DataTemplate > <Ellipse MinHeight="4" MinWidth="4" Margin="2" Fill="{Binding}"/> </DataTemplate> </ItemsControl.ItemTemplate> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DataTemplate> </Grid.Resources> <calendar:SfCalendarDateRangePicker x:Name="calendarDateRangePicker" MinWidth="180" HorizontalAlignment="Center" VerticalAlignment="Center"> <FlyoutBase.AttachedFlyout> <editor:DropDownFlyout> <calendar:SfCalendar SelectionMode="Range" SelectedRange="{x:Bind calendarDateRangePicker.SelectedRange, Mode=TwoWay}" > <calendar:SfCalendar.Resources> <ResourceDictionary> <!-- Resources and color keys for Calendar Control --> <SolidColorBrush x:Key="SyncfusionCalendarItemOutOfScopeForeground" Color="SlateGray" Opacity="0.5" /> <SolidColorBrush x:Key="SyncfusionCalendarWeekItemForeground" Color="{ThemeResource SystemBaseMediumLowColor}" /> <x:Double x:Key="SyncfusionSubtitleAltFontSize">16</x:Double> <Thickness x:Key="SyncfusionCalendarItemMargin">1</Thickness> <x:Double x:Key="SyncfusionBodyFontSize">13</x:Double> <Style TargetType="calendar:CalendarItem"> <Setter Property="CornerRadius" Value="14"/> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="VerticalContentAlignment" Value="Stretch"/> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <Grid MinWidth="40" MinHeight="40"> <ContentControl HorizontalAlignment="Center" VerticalAlignment="Center" Margin="2" Content="{Binding DisplayText}"/> <ContentControl Margin="3" HorizontalAlignment="Center" VerticalAlignment="Bottom" Content="{Binding Date}" ContentTemplate="{StaticResource customTemplate}" /> </Grid> </DataTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> </calendar:SfCalendar.Resources> </calendar:SfCalendar> </editor:DropDownFlyout> </FlyoutBase.AttachedFlyout> </calendar:SfCalendarDateRangePicker> </Grid>
