I need to process with IsOpen property in a code Behind.
XAML:
DataContext="{Binding RelativeSource={RelativeSource Self}}"
IsOpen="{Binding ChildWindow_IsOpen}"
Code Behind:
public bool ChildWindow_IsOpen
{
get { return (bool)GetValue(WindowProperty); }
set { SetValue(WindowProperty, value); }
}
public static readonly DependencyProperty WindowProperty = DependencyProperty.Register("ChildWindow_IsOpen", typeof(bool), typeof(MainWindow));
MainWindow:
ChildWindow childWindow = new ChildWindow();
private async void button3_OnClick(object sender, RoutedEventArgs e)
{
if (childWindow.ChildWindow_IsOpen == false)
{
await this.ShowChildWindowAsync(new ChildWindow() { IsModal = false, AllowMove = true, }, RootGrid);
childWindow.ChildWindow_IsOpen = true;
}
else if (childWindow.ChildWindow_IsOpen == true)
{
childWindow.Close();
childWindow.ChildWindow_IsOpen = false;
}
else
{
return;
}
}
So my question is how to do that in a professional way?
My code doesn't affect to ChildWindow at all.
Thanks in advance!
Update: ChildWindow's XAML is situated in MainWindow XAML. This works like a charm!
private void button1_Click(object sender, RoutedEventArgs e)
{
if (ChildWindow.IsOpen == false)
{
ChildWindow.IsOpen = true;
}
else if (ChildWindow.IsOpen == true)
{
ChildWindow.Close();
}
else
{
return;
}

What do you mean by "professional"? What do you mean "My code doesn't affect to ChildWindow"? You seem to be doingchildWindow.ChildWindow_IsOpenjust fine

The “professional” way would be to use MVVM

@DaveM Exactly. WPF/UWP and XAML were designed with MVVM in mind. While you can use any other approach and pattern, doing so missed about 90% of it's power and runs into issues at every other corner. This does not look like proper MVVM, so I asume the issue is there.

@MickyD, first button click should open ChildWindow, second one should close ChildWindow. However it doesn't happen.

@Christopher Since the OP wants to open/close windows, MVVM has questionable benefit for this particular problem. If you intend to open a view from the viewmodel (including by indirect means of injected window'ing services into the VM) then that is a violation of the MVVM best practices
