Floating window over existing window - any ideas

[Jonathan]

Any ideas how I can create a small floating window (modal) over and existing WPF window?

I want to show a digital clock on the window/form at all times.

 

thanks in advance

Hello Jonathan,

What we could suggest you in order to achieve the desired is to create an instance of RadWindow and set its Owner property to the MainWindow before calling its ShowDialog method - thus the RadWindow will always be on top of their parent:

RadWindow window = new RadWindow();
...
window.Owner = this;
window.ShowDialog()

Hopes this helps.

On showdialog I get

 

An unhandled exception of type 'System.InvalidOperationException' occurred in PresentationFramework.dll

Additional information: Cannot set Owner property to a Window that has not been shown previously.

 

 

      public DashBoard()
        {
            InitializeComponent();


            Clock clock = new Clock();
            clock.Owner = this;
            clock.ShowDialog();

 

Any ideas?  thanks!

Hello Jonathan,

The thrown exception is an expected one as you are trying to set the Owner property to a Window that is not yet initialized and visualized completely. We suggested you to handle the Loaded event of the Window and create RadWindow inside it - thus it will be sure that the Window is completely loaded:

public MainWindow()
{
    InitializeComponent();
    this.Loaded += MainWindow_Loaded;
}

void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    RadWindow window = new RadWindow();

    window.Owner = this;
    window.Show();
}

Hopes this helps.
