自定义一个按钮控件
按钮控件很简单，我们在项目中有时把样式封装起来，添加依赖属性，也是为了统一。
这里举例，单纯的图标控件怎么设置
1、UserControl界面样式
<UserControl x:Class="WpfApplication12.IconButton" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" Loaded="IconButton_OnLoaded">
<UserControl.Resources>
<Style TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<Rectangle x:Name="T_Rectangle" Height="15" Width="15">
<Rectangle.Fill>
<ImageBrush ImageSource="{Binding ImagesSource}"></ImageBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}"></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="T_Rectangle" Property="Height" Value="18"></Setter>
<Setter TargetName="T_Rectangle" Property="Width" Value="18"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Rectangle" Property="Height" Value="20"></Setter>
<Setter TargetName="T_Rectangle" Property="Width" Value="20"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Grid>
<Button Click="ButtonBase_OnClick"></Button>
</Grid>
</UserControl>
2、后台设置，我这边只添加了个图片路径和事件委托。其它的自己加吧
public partial class IconButton : UserControl
{
public IconButton()
{
InitializeComponent();
}
public ImageSource ImagesSource
{
get { return (ImageSource)GetValue(ImagesSourceProperty); }
set { SetValue(ImagesSourceProperty, value); }
}
public static readonly DependencyProperty ImagesSourceProperty = DependencyProperty.Register("ImagesSource",
typeof(ImageSource), typeof(IconButton));
private void IconButton_OnLoaded(object sender, RoutedEventArgs e)
{
var data = new IconButtonModel()
{
ImagesSource = ImagesSource
};
this.DataContext = data;
}
public delegate void ClickEventArgs(object sender, RoutedEventArgs e);
public event ClickEventArgs Click;
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
if (Click != null)
{
Click(sender, e);
}
}
}
public class IconButtonModel
{
public ImageSource ImagesSource { get; set; }
}
