Change "Today Highlighted" background color.

[Puhn]

Hi, 

How do I change the Today Highlighted background color? I've tried edit template but haven't found any related control I can change.

Thanks.

Hi,

Thank you for your question.

Add the following style to the resources of your page/application: 

<Style TargetType="telerikCalendar:CalendarButton">
    <Setter Property="Padding" Value="0" />
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    <Setter Property="VerticalContentAlignment" Value="Stretch"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerikCalendar:CalendarButton">
                <Grid x:Name="LayoutRoot" Background="{TemplateBinding Background}">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Disabled">
                                <Storyboard>

The telerikInput prefix is mapped to the following namespace:

xmlns:telerikCalendar="clr-namespace:Telerik.Windows.Controls.Calendar;assembly=Telerik.Windows.Controls.Input"

In order to change the color of Today, you need to modify the background of the TodayVisual (it is highlighted). 

I hope this information helps. Let me know if you need futher assistance.
