Question

In my WPF application, I displayed some Checkbox dynamically. The Name and Content of these Checkbox come from a Table in the Database.

...
StackPanel innerStack = new StackPanel();
        List<Course> courses = ldc.Courses.ToList();
        var count = courses.Count();
        var b = ldc.Books.Single(x=>x.BookID==1);
        foreach (var c in courses)
        {
            CheckBox cb = new CheckBox();
            cb.Name = c.CourseID.ToString();
            cb.Content = c.CourseID.ToString();
            var x = from bc in ldc.CourseAndBooks
                    where bc.BookID == b.BookID
                    select bc.CourseID;
            if (x.Contains(c.CourseID))
            {
                cb.IsChecked = true;
            }

            cb.AddHandler(CheckBox.CheckedEvent, new RoutedEventHandler(course_Checked));
            cb.AddHandler(CheckBox.UncheckedEvent, new RoutedEventHandler(course_Unchecked));
            innerStack.Children.Add(cb);
        }
        Grid.SetColumn(innerStack,0);
        Grid.SetRow(innerStack,0);
        Grid.SetColumnSpan(innerStack,1);
        Grid.SetRowSpan(innerStack,1);
        grid.Children.Add(innerStack);
        ...

I added Checked and Unchecked event too to manipulate the checked item in the Database.

 private void course_Checked(object sender, RoutedEventArgs e)
    { 
        MessageBox.Show("checked"); // it works
        // How to identify cb.Name here to perform some database query?
    }
    private void course_Unchecked(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Unchecked"); // it works
        // How to identify cb.Name here to perform some database query?
    }

So, how can I get the name of the checked/unchecked Checkbox name in the Checked/Unchecked` event method. Any suggession ? Thankyou.

Fairly sure you can cast the sender to a CheckBox and it will be what you’re looking for.
