WPF UserControl with generic code-behind

Question

I have this code behind:

CustomUserControl.xaml.cs

namespace MyProject
{
    public partial class CustomUserControl : UserControl
    {
             


        

Answer 1

Haven't found my solution anywhere else so far. The main difference is, that I have got one .xaml file for the generic user control class and not one for each actual user control.

GenericUserControl.xaml.cs

using System.Windows.Controls;

namespace TestGenericUserControl
{
    public abstract partial class GenericUserControl : UserControl
    {
        // If you use event handlers in GenericUserControl.xaml, you have to define 
        // them here as abstract and implement them in the generic class below, e.g.:

        // abstract protected void MouseClick(object sender, MouseButtonEventArgs e);
    }

    public class GenericUserControl : GenericUserControl
    {
        // generic properties and stuff

        public GenericUserControl()
        {
            InitializeComponent();
        }
    }

    // To use the GenericUserControl in XAML, you could define:
    public class GenericUserControlString : GenericUserControl { }
    // and use it in XAML, e.g.:
    // 
    // alternatively you could probably (not sure) define a markup extension to instantiate
    // it directly in XAML
}
