TimeSpanPicker Styling

The TimeSpanPicker control for .NET MAUI provides styling options for customizing its appearance. You can style the TimeSpanPicker itself, as well as its popup or dropdown depending on the PickerMode setting.

The control supports the following styling properties:

• BackgroundColor—Defines the background color of the picker.
• BorderColor—Defines the border color of the picker.
• BorderThickness—Specifies the border thickness of the picker. The default value is new Thickness(0,0,0,1).
• CornerRadius—Specifies the corner radius of the picker.
• ClearButtonStyle(of type Style with target type RadButton)—Defines the style applied to the Clear button.
• ToggleButtonStyle(of type Style with target type RadButton)—Specifies the style of the Toggle button.
• PlaceholderLabelStyle(of type Style with target type Label)—Defines the style applied to the placeholder label.
• DisplayLabelStyle(of type Style with target type Label)—Defines the style applied to the label which is visualized when a time duration is selected.   The following Style properties are related to the spinner controls inside the popup/dropdown:  
• SpinnerStyle(of type Style with target type telerik:RadSpinner)—Defines the style applied to the spinner item and the selected item interval.
• SpinnerHeaderStyle(of type Style with target type Label)—Specifies the style applied to the spinner header labels.
• SelectionHighlightStyle(of type Style with target type telerikPrimitives:RadBorder)—Specifies the style applied to the selection inside the popup.

Namespaces

When defining some of these styles, you will need to include additional namespaces, so that the target types are properly resolved.

If you use SelectionHighlightStyle, you need to add the following namespace:

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

If you use SpinnerStyle, you need to add the following namespace:

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

Example

The following example shows how the styling properties are applied.

Let's have the following TimeSpan Picker definition:

<telerik:RadTimeSpanPicker BorderColor="#8660C5"
                           SpinnerHeaderStyle="{StaticResource spinnerHeaderStyle}"
                           SpinnerStyle="{StaticResource spinnerStyle}"
                           SelectionHighlightStyle="{StaticResource selectionHighlightStyle}"
                           DisplayLabelStyle="{StaticResource displayLabelStyle}"
                           PlaceholderLabelStyle="{StaticResource placeholderLabelStyle}"
                           ClearButtonStyle="{StaticResource clearButtonStyle}"
                           ToggleButtonStyle="{StaticResource toggleButtonStyle}"
                           IsClearButtonVisible="True"
                           IsToggleButtonVisible="True"
                           AutomationId="timeSpanPicker"/>
