Deriving from Custom UserControl

Question

Hi

Is it possible to do the following in WPF:

BaseUserControl.xaml

   <UserControl x:Name="BaseUserControl"></UserControl>

BaseUserControl.xaml.cs

   public class BaseUserControl : UserControl {}

Now derive another control from this control:

InheritedControl.xaml

<local:BaseUserControl x:Name= "InheritedControl"></local:BaseUserControl>

InheritedControl.xaml.cs

public class InheritedControl: BaseUserControl {}

Thanks

It is possible:

Make sure your derivation turns from this:

<UserControl x:Class="MyProject..."
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        
    xmlns:s="clr-namespace:System;assembly=mscorlib"
    >
......

Into this:

<local:BaseUserControl x:Class="MyProject..."
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        
    xmlns:s="clr-namespace:System;assembly=mscorlib"
    >
...
