    The task of generating multiple controls for multiple items from some list is best solved using ItemsControl:

    
        
            
                

    This ItemsControl named "itemsList" contains buttons with custom template. Each button will display one the Name of one item from list.

    DataEntity is a class which contains values from db, e.g.

    public class DataEntity
    {
        public string Name { get; set; }
    }
    

    Items list is linked to ItemsControl via ItemsSource property (in my demo I'm doing it in window code-behind in constructor)

    itemsList.ItemsSource = new ObservableCollection
    {
        new DataEntity { Name = "A" },
        new DataEntity { Name = "B" },
        new DataEntity { Name = "C" },
    };
    

    Buttons have click handler attached ("ItemButtonClick"). The clicked button is determined from sender argument:

    private void ItemButtonClick(object sender, RoutedEventArgs e)
    {
        var button = (Button)sender;
        var item = button.DataContext as DataEntity;
    
        MessageBox.Show("Clicked " + item.Name);
    }
