如何在自定义用户控件上创建点击事件？ [英] How can I create a click event on a custom user control?

问题描述

我已经创建了一个自定义用户控件。是否有可能添加一个点击事件，以便当有人点击控件区域的任何地方时，会触发点击事件？

I've created a custom user control. Is it possible for me to add a click event so that when someone clicks anywhere in the area of the control, a click event is fired?

用户控件被定义为：

XAML：

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}">
    <StackPanel Orientation="Vertical">
        <Image  Source="{Binding TabItemImage}" HorizontalAlignment="Center" Stretch="None" VerticalAlignment="Top" />
        <TextBlock Text="{Binding TabItemText}" FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Bottom" />
    </StackPanel>
</Grid>

C＃：

public partial class TabItem : UserControl
{
    public static readonly DependencyProperty ImageProperty = DependencyProperty.Register("TabItemImage", typeof(string), typeof(TabItem), null);
    public static readonly DependencyProperty TextProperty = DependencyProperty.Register("TabItemText", typeof(string), typeof(TabItem), null);

    public string TabItemImage
    {
        get { return (string)GetValue(ImageProperty); }
        set { SetValue(ImageProperty, value); }
    }

    public string TabItemText
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }

    public TabItem()
    {
        InitializeComponent();
        this.DataContext = this;
    }
}

使用简单：

<tabs:TabItem TabItemText="OVERVIEW" TabItemImage="/Resources/Images/overview.png" />

理想情况下，我可以修改用户控件，以便我可以指定点击事件，例如

Ideally I'd be able to modify the user control so that I could specify the click event, e.g.

<tabs:TabItem 
    TabItemText="OVERVIEW" 
    TabItemImage="/Resources/Images/options_64.png" 
    Click="TabItem_Clicked"/> <!-- when someone clicks the control, this fires -->

这是可能吗？如果是这样，我需要做什么来创建自定义用户控件上的点击事件？

Is this possible? If so, what do I need to do to create a click event on a custom user control?

推荐答案

sthotakura，有一个很好的这将是一个伟大的方式来做到这一点。但是，如果此UserControl没有多个点击事件，为什么不使用定义自定义UserControl的任何数量的mouseclick事件。

sthotakura, Has a good point and that would be a great way to do it. However, If you don't have more than one click event for this UserControl, Why dont you just use the any of the number of mouseclick events that come with defining a custom UserControl.

我不知道你可以将数据文本设置为自己的...这很有趣。我正在修改我现在创建的自定义对话框.. :)感谢您教我一些东西。

I didn't know you could set the datacontext to its self... That is interesting. I am going modify a custom Dialog that i created now.. :) Thanks for teaching me something.

CS：

public partial class TestControl : UserControl
{
    public static readonly DependencyProperty ImageProperty = DependencyProperty.Register("TabItemImage" , typeof(string) , typeof(TabItem) , null);
    public static readonly DependencyProperty TextProperty = DependencyProperty.Register("TabItemText" , typeof(string) , typeof(TabItem) , null);

    public string TabItemImage
    {
        get { return (string)GetValue(ImageProperty); }
        set { SetValue(ImageProperty , value); }
    }

    public string TabItemText
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty , value); }
    }

    public TestControl()
    {
        InitializeComponent();
        this.DataContext = this;
    }

    // or

    private void TestControl_OnMouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        // Add logic...
    }

    // or

    private void TestControl_OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        // Add logic...
    }

    // or

    private void TestControl_OnMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
    {
        // Add logic...
    }
}
