Close current UserControl

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);

Answer 2

Window.GetWindow(this).Close();

You don't need to use a new variable, you can use it directly.

Answer 3

You could set the Visibility property of the control you want to "close" to Collapsed.

This way it will not be displayed anymore but will still be present in the visual tree if you need to reuse it later.

Answer 4

In your button click handler try :

Window parentWindow = (Window)this.Parent;
parentWindow.Close();

Answer 5

private void Button_Click(object sender, RoutedEventArgs e)
{

    (this.Parent as searchEditPanel).Children.Remove(this);

}
