Wpf 8.1 HubSection

Question

我在HubSection中有Grid中的Button，我想在从kg到ibs之后点击Button.Content并从ibs到kg之后更改clik

这是我在XAML中的声明

<Button Content="Button" HorizontalAlignment="Left" Margin="220,-19,0,0" VerticalAlignment="Top" FontSize="18" Loaded="buttonWeight_Loaded" Click="buttonWeight_Click"/>

这是我的Loaded方法

private void buttonWeight_Loaded(object sender, RoutedEventArgs e)
    {
        _buttonWeight = (Button)sender;
        _buttonWeight.Click += buttonWeight_Click;
    }

然后点击方法

private void buttonWeight_Click(object sender, RoutedEventArgs e)
{

if ((_buttonWeight.Content)as String ==this.kg)
{
    _buttonWeight.Content = this.ibs;
}
else { _buttonWeight.Content = this.kg; }

}

点击后我总是有ibs为什么？

Answer 1

您正在注册两次收听Click事件。进入按钮的xaml声明后：

Click="buttonWeight_Click".

并且在Loaded事件中一次：

_buttonWeight.Click += buttonWeight_Click;

摆脱其中任何一个，你的代码就可以了。
