关于WPF自定义空间库的问题
最近在学习WPF，并尝试写了一个自定义控件，但是，遇到两个问题：将自定义控件拖放到窗体后，
1、如果自定义样式表中是动态绑定样式，则控件在窗体上看不到，除非是静态绑定样式。
2、更改窗体中控件的属性，发现控件没有发生变化
代码如下：我中间会用红字说明
1、自定义控件cs文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfCustomControlLibrary1
{
public class CustomControl : Control
{
public static readonly DependencyProperty ShowBorderProperty;
/// <summary>
/// 获取或设置显示边框
/// </summary>
public bool ShowBorder
{
get { return (bool)GetValue(ShowBorderProperty); }
set { SetValue(ShowBorderProperty, value); }
}
static CustomControl()
{
ShowBorderProperty = DependencyProperty.Register("ShowBorder", typeof(bool), typeof(CustomControl), new PropertyMetadata(false));
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
}
}
}
2、自定义控件样式文件
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfCustomControlLibrary1">
<ControlTemplate x:Key="BorderTemplate" TargetType="{x:Type ContentControl}">
<Grid>
<Grid.Resources>
<local:BoolToVisibilityConverter x:Key="BoolToVisibilityConverter" />
<local:BoolToVisibilityInverseConverter x:Key="BoolToVisibilityInverseConverter"/>
</Grid.Resources>
<Border Background="#FF7496C2" BorderThickness="0" CornerRadius="3" Padding="1" Visibility="{Binding Path=ShowBorder, Converter={StaticResource BoolToVisibilityConverter}}">
<Grid>
<Border Margin="0" BorderThickness="0" CornerRadius="2" Background="#FFEAF2FC" />
<Border Margin="1" CornerRadius="1" Background="#FFCEE1F8">
</Border>
</Grid>
</Border>
<Grid Background="#FFCEE1F8" Visibility="{Binding Path=ShowBorder, Converter={StaticResource BoolToVisibilityInverseConverter}}" />
<ContentPresenter Margin="11" />
</Grid>
</ControlTemplate>
<ControlTemplate x:Key="ContentTemplate" TargetType="{x:Type local:CustomControl}">
<Grid SnapsToDevicePixels="True">
<ContentControl x:Name="PART_Border" HorizontalContentAlignment="Left" Template="{StaticResource（这里不能用动态资源？） BorderTemplate}" VerticalContentAlignment="Stretch" Focusable="False">
<Grid>
<ContentControl Grid.Row="2" Focusable="False" />
</Grid>
</ContentControl>
</Grid>
</ControlTemplate>
<Style TargetType="{x:Type local:CustomControl}">
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="Template" Value="{StaticResource（这里不能用动态资源？） ContentTemplate}"/>
</Style>
</ResourceDictionary>
3、样式中用到的两个cs（发现好像不起作用，程序根本没有调用这里，不能断点）
using System;
using System.Globalization;
using System.Windows;
using System.Windows.Data;
namespace WpfCustomControlLibrary1
{
public class BoolToVisibilityConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (((bool)value) ? Visibility.Visible : Visibility.Collapsed);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return (((Visibility)value) == Visibility.Visible);
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Data;
using System.Globalization;
using System.Windows;
namespace WpfCustomControlLibrary1
{
public class BoolToVisibilityInverseConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (((bool)value) ? Visibility.Collapsed : Visibility.Visible);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return (((Visibility)value) == Visibility.Collapsed);
}
}
}
4、窗体代码
--------------------编程问答--------------------
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors" xmlns:my="clr-namespace:WpfCustomControlLibrary1;assembly=WpfCustomControlLibrary1">
<Grid>
<my:CustomControl HorizontalAlignment="Left" Margin="83,57,0,0" Name="customControl1" VerticalAlignment="Top" Height="193" Width="231" ShowBorder="True"（就是这里，在设计状态和运行状态，都没有变化） />
</Grid>
</Window>
//设置边框大小
public static new readonly DependencyProperty BorderThicknessProperty;
public new Thickness BorderThickness
{
get { return (Thickness)GetValue(BorderThicknessProperty); }
set { SetValue(BorderThicknessProperty, value); }
}
private static void BorderThicknessChange(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
TMarquee tMarquee = (TMarquee)sender;
tMarquee.border1.BorderThickness = tMarquee.BorderThickness;
}
static TMarquee()
{
BorderThicknessProperty = DependencyProperty.Register("BorderThickness", typeof(Thickness), typeof(TMarquee), new FrameworkPropertyMetadata(new Thickness(3), BorderThicknessChange),
ShareClass.ValueTypeCheck<Thickness>);
}
没有定义DependencyPropertyChangedCallback --------------------编程问答-------------------- tMarquee.border1.BorderThickness = tMarquee.BorderThickness;
？？？？
border1是样式表中的一个element的名字吗？为什么BoolToVisibilityConverter没有被调用呢？ --------------------编程问答-------------------- 2、自定义控件样式，上面发的有问题，重新发一遍
这里有转换方法调用（11、18行），和两个设置Template时候的绑定(24、33行)
为什么实际运行时候没有调用转换方法？
为什么设置Template绑定的时候用动态绑定后，拖到界面上的控件样式没有起作用呢?
要自定义一个控件，然后生成dll供别人使用，在别人引用后，拖到窗体上就是带有默认样式的，应该怎么做呢？谁给个例子？

补充：.NET技术 , C#
