本文介绍了如何将MouseDown事件放在样式中?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这样做:
XAML:
<Window x:Class="Test239992.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<StackPanel>
<TextBlock Tag="1" Text="Customers" MouseDown="Handle_Click"/>
<TextBlock Tag="2" Text="Appointments" MouseDown="Handle_Click"/>
</StackPanel>
</Window>
代码背后:
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
namespace Test239992
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
private void Handle_Click(object sender, MouseButtonEventArgs e)
{
int id = Int32.Parse(((TextBlock)sender).Tag.ToString());
MessageBox.Show("you chose id " + id.ToString());
}
}
}
但是我把MouseDown事件放在一个样式中,这样就给我了错误类型System.Windows.Controls.TextBlock找不到样式属性MouseDown:
But how do I put the MouseDown event in a style, this gives me the error "Cannot find the Style Property 'MouseDown' on the type 'System.Windows.Controls.TextBlock'":
<Window x:Class="Test239992.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Window.Resources>
<Style TargetType="{x:Type TextBlock}" x:Key="ClickableTextBlockStyle">
<Setter Property="MouseDown" Value="Handle_Click" />
</Style>
</Window.Resources>
<StackPanel>
<TextBlock Tag="1" Text="Customers" Style="{DynamicResource ClickableTextBlockStyle}"/>
<TextBlock Tag="2" Text="Appointments" Style="{DynamicResource ClickableTextBlockStyle}"/>
</StackPanel>
</Window>
推荐答案
尝试:)
<Style TargetType="{x:Type TextBlock}" x:Key="ClickableTextBlockStyle">
<EventSetter Event="MouseDown" Handler="Handle_Click" />
</Style>
