我有一个LonglistSelector,它显示一个项目列表,每个项目都有一个按钮:

我的LongListSelector有一个SelectionChanged事件

private void MyLLS_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        var item = (MyItemType)MyLLS.SelectedItem;
        // Job 1 goes here
    }

并且LLS中的项目中的每个按钮都有一个点击事件:

private void btDownload_Click(object sender, RoutedEventArgs e)
    {
        var button = (MyItemType)(sender as Button).DataContext;          
        // Job 2 goes here
    }

问题是,当我点击一个按钮时,它将处理作业2,之后它将处理作业1.那么我怎样才能完成点击按钮事件的工作2?

您应该使用布尔标志来确定它,就像:

bool isBtnClicked = false;

private void MyLLS_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    // check if button is clicked, if so, return and reset the isBtnClicked flag.
    if (isBtnClicked)
    {
        isBtnClicked = false;
        return;
    }
    var item = (MyItemType)MyLLS.SelectedItem;
    // Job 1 goes here
}

private void btDownload_Click(object sender, RoutedEventArgs e)
{
    var button = (MyItemType)(sender as Button).DataContext; 
    // set it true when button clicked
    isBtnClicked = true;         
    // Job 2 goes here
}
