我正在使用Xceed DateTimePicker控件。问题出在它的日历大小：当您放大控件本身的字体时，其弹出日历的大小和字体不会更改。如何更改弹出窗口的大小？

在DateTimePicker中修改Calendar的Style。诀窍是将日历的ControlTemplate Package 在一个大小合适的ViewBox中，例如Width = Height = 300，如下所示：

<Window x:Class="View.SampleDlg"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"

    <xctk:DateTimePicker 
        ...
        CalendarWidth="{Binding RelativeSource={RelativeSource Self}, Path=CalendarWidth, Converter={viewModel:SizeConverter Percentage=200}, Mode=OneTime}"
    />
</Window>

以上使用的转换器定义如下：

using System;
using System.Globalization;
using System.Windows.Data;
using System.Windows.Markup;

namespace ViewModel
{
    public abstract class ConverterBase
        : MarkupExtension
        , IValueConverter
    {
        public abstract object Convert(object value, Type targetType, object parameter, CultureInfo culture);
        public virtual object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            return this;
        }
    }

    [ValueConversion(typeof(double), typeof(double))]
    public class SizeConverter : ConverterBase
    {
        public uint Percentage { get; set; }
        public override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var num = (double)value;
            return (num * this.Percentage) / 100;
        }
    }
}
