关闭当前的UserControl [英] Close current UserControl

问题描述

我有一个Window1.xaml主窗口；并在发生一些事件之后，显示UserControl EditFile.xaml。

I have a Window1.xaml main Window; and after some event, I display a UserControl EditFile.xaml.

后面的代码是：

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，如何关闭打开/添加的

And now, how can I close the opened/added UserControl from its content by clicking a Cancel button or something like that?

推荐答案

您尝试过吗？

searchEditPanel.Children.Remove(_EditFileControle);

也许这会有所帮助： http://sachabarber.net/?p=162

如果没有：向您的UserControl添加属性：

if it doesn't: Add a property to your UserControl:

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
}

现在您应该可以这样做：

Now you should be able to do this:

 // Somewhere in your UserControl
if (this.ParentControl != null)
    this.ParentControl.Children.Remove(this);
