Question

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

The code behind is:

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
}

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

Answer 1

Have you tried this?

searchEditPanel.Children.Remove(_EditFileControle);

Another Suggestion:

Maybe this helps: http://sachabarber.net/?p=162

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

public UserControl ParentControl {get;set;}

Now modify your code:

private void button1_Click(object sender, RoutedEventArgs e)
{
    //searchEditPanel.Children.Clear();
    whichSelected = listViewFiles.SelectedIndex;
    _EditFileControle.ParentControl = this;
    searchEditPanel.Children.Add(_EditFileControle);        //this is Grid
}

Now you should be able to do this:

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