Blu*_*Man 4 wpf user-controls children parent
我有一个Window1.xaml主窗口; 在一些事件之后,我显示一个UserControl EditFile.xaml.
背后的代码是:
public static int whichSelected = -1;
private void button1_Click(object sender, RoutedEventArgs e)
{
//searchEditPanel.Children.Clear();
whichSelected = listViewFiles.SelectedIndex;
searchEditPanel.Children.Add(_EditFileControle); //this is Grid
}

现在,如何通过单击"取消"按钮或类似内容来关闭打开/添加的UserControl?
你试过这个吗?
searchEditPanel.Children.Remove(_EditFileControle);

如果没有:向您的 UserControl 添加一个属性:
public UserControl ParentControl {get;set;}

现在修改您的代码:
private void button1_Click(object sender, RoutedEventArgs e)
{
//searchEditPanel.Children.Clear();
whichSelected = listViewFiles.SelectedIndex;
_EditFileControle.ParentControl = this;
searchEditPanel.Children.Add(_EditFileControle); //this is Grid
}

现在您应该能够执行以下操作:
// Somewhere in your UserControl
if (this.ParentControl != null)
this.ParentControl.Children.Remove(this);
