解决方案

为了改变控件的视觉外观，你必须改变它们的默认样式或控件模板。如果你已经为 WPF 安装了 Telerik UI，你可以在这里找到控件的默认样式：

C:\Program Files (x86)\Progress\<Your Telerik Version Folder>\Themes.Implicit\WPF40

从您的屏幕截图中，我猜您正在使用Fluent主题。的资源RadDatePicker可以在 中找到\Fluent\Themes\Telerik.Windows.Controls.Input.xaml。

您在屏幕截图中描述的边框实际上是日历控件的背景。它似乎只是一个边框，因为日历中的按钮有一个边距，使背景可见。

正如您在下面看到的，LayoutRoot Grid在 的控件模板中定义了一个边距CalendarButton。

<ControlTemplate TargetType="calendar:CalendarButton">
   <Grid x:Name="LayoutRoot" Background="Transparent" Margin="{StaticResource CalendarButtonMargin}">
   <!-- ...other template code. -->
</ControlTemplate>

为了删除边距，复制CalendarButtonStyle样式并删除其中Margin的。

<Style x:Key="MyCalendarButtonStyle" TargetType="calendar:CalendarButton">
   <Setter Property="materialControls:MaterialAssist.CornerRadius" Value="0"/>
   <Setter Property="materialControls:MaterialAssist.MouseOverBrush" Value="{telerik:FluentResource ResourceKey=MouseOverBrush}"/>

                  <Setter TargetName="BorderVisual" Property="BorderBrush" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background, Mode=OneWay}"/>
                  <Setter Property="Foreground" Value="{telerik:FluentResource ResourceKey=AccentBrush}"/>
               </Trigger>
               <Trigger Property="ButtonType" Value="WeekName">
                  <Setter TargetName="Fluent" Property="IsEnabled" Value="False"/>
                  <Setter TargetName="Content" Property="Foreground" Value="{telerik:FluentResource ResourceKey=MarkerBrush}"/>
                  <Setter TargetName="Content" Property="FontWeight" Value="SemiBold"/>
                  <Setter TargetName="LayoutRoot" Property="Margin" Value="0"/>
                  <Setter TargetName="BorderVisual" Property="Visibility" Value="Collapsed"/>
               </Trigger>
            </ControlTemplate.Triggers>
         </ControlTemplate>
      </Setter.Value>
   </Setter>
</Style>

然后创建一个样式一个RadCalendar使用这个样式的CalendarButton样式。

<Style x:Key="MyCalendarStyle" TargetType="telerik:RadCalendar" BasedOn="{StaticResource {x:Type telerik:RadCalendar}}">
   <Setter Property="DayButtonStyle" Value="{StaticResource MyCalendarButtonStyle}"/>
   <Setter Property="MonthButtonStyle" Value="{StaticResource MyCalendarButtonStyle}"/>
   <Setter Property="YearButtonStyle" Value="{StaticResource MyCalendarButtonStyle}"/>
   <Setter Property="DecadeButtonStyle" Value="{StaticResource MyCalendarButtonStyle}"/>
</Style>

然后创建一个RadDatePicker使用该样式的RadCalendar样式。

<Style x:Key="MyDatePickerStyle" TargetType="{x:Type telerik:RadDatePicker}" BasedOn="{StaticResource {x:Type telerik:RadDatePicker}}">
   <Setter Property="CalendarStyle" Value="{StaticResource MyCalendarStyle}"/>
</Style>

现在您可以将这种样式应用到任何日期选择器，像这样。

<telerik:RadDatePicker Style="{StaticResource MyDatePickerStyle}"/>

如果您希望此样式应用于RadDatePicker范围内的所有 s，则可以添加隐式样式。

<Style TargetType="{x:Type telerik:RadDatePicker}" BasedOn="{StaticResource MyDatePickerStyle}"/>

这是生成的日历的屏幕截图。
