创建带有控件模板的图像+文本按钮? [英] Creating an image+text button with a control template?

问题描述

我厌倦了一次又一次地创建相同的图像+文本按钮，我想将标记移至控件模板.这是我的问题:我需要提供模板绑定，以将图像和文本添加到模板化按钮上，并且Button控件似乎没有可以绑定的属性.

I am tired of creating the same image+text button over and over again, and I would like to move the markup to a control template. Here is my problem: I need to provide template bindings to add the image and text to the templated button, and the Button control doesn't seem to have properties that I can bind to.

到目前为止，我的模板看起来像这样(对于未知的模板绑定，带有"???"):

My template looks like this so far (with '???' for the unknown template bindings):

<ControlTemplate x:Key="ImageButtonTemplate" TargetType="{x:Type Button}">
    <StackPanel Height="Auto" Orientation="Horizontal">
        <Image Source="{TemplateBinding ???}" Width="24" Height="24" Stretch="Fill"/>
        <TextBlock Text="{TemplateBinding ???}" HorizontalAlignment="Left" Foreground="{DynamicResource TaskButtonTextBrush}" FontWeight="Bold"  Margin="5,0,0,0" VerticalAlignment="Center" FontSize="12" />
    </StackPanel>
</ControlTemplate>

是否可以使用控件模板来创建此图像+文本按钮，还是我必须转到用户控件才能执行此操作?如果可以通过控制模板完成，该如何设置模板绑定?

Is it possible to create this image+text button using a control template, or do I have to go to a user control to do it? If it can be done with a control template, how do I set up the template bindings?

推荐答案

定义这样的CustomControl

Define a CustomControl like this

public class MyButton : Button
{
    static MyButton()
    {
       //set DefaultStyleKeyProperty
    }   

    public ImageSource ImageSource
    {
        get { return (ImageSource)GetValue(ImageSourceProperty); }
        set { SetValue(ImageSourceProperty, value); }
    }

    // Using a DependencyProperty as the backing store for ImageSource.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty ImageSourceProperty =
        DependencyProperty.Register("ImageSource", typeof(ImageSource), typeof(MyButton), new UIPropertyMetadata(null));
}

在主题文件夹的generic.xaml中

<Style TargetType="{x:Type MyButton}">
    <Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type MyButton}">
            <StackPanel Height="Auto" Orientation="Horizontal">
                <Image Source="{TemplateBinding ImageSource}" Width="24" Height="24" Stretch="Fill"/>
                <TextBlock Text="{TemplateBinding Content}" HorizontalAlignment="Left" Foreground="{DynamicResource TaskButtonTextBrush}" FontWeight="Bold"  Margin="5,0,0,0" VerticalAlignment="Center" FontSize="12" />
            </StackPanel>
        </ControlTemplate>
    </Setter.Value>
    </Setter>
</Style>
