Inherit from a WPF page

Question

I have a page which contains an overridable property "FileName". I want to create the whole page and inherit from them to have same pages but with different filename.

Is this possible?

Main page XAML:

    <Page x:Class="Batcher_File"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
      xmlns:my="clr-namespace:TB_InstallSystem"
      DataContext="{Binding RelativeSource={RelativeSource Self}}"
      mc:Ignorable="d" 
      d:DesignHeight="300" d:DesignWidth="600"
      Title="Batcher">
    </Page>

Codebehind:

Class Batcher_File
    Private _fiBatch As New IO.FileInfo(TB.SystemMain.AppPath & "myfile.xml")
    Public Overridable Property fiBatch As IO.FileInfo
        Get
            Return _fiBatch
        End Get
        Set(value As IO.FileInfo)
            _fiBatch = value
        End Set
    End Property
End Class

Second Page XAML ??:

<!-- -->

Second Page Codebehind:

Public Class Batc_After
    Inherits Batcher_Filer

    Private _fiBatch As New IO.FileInfo(TB.SystemMain.AppPath & "batch_after.xml")
    Public Overrides Property fiBatch As IO.FileInfo
        Get
            Return _fiBatch
        End Get
        Set(value As IO.FileInfo)
            _fiBatch = value
        End Set
    End Property




End Class

I was doing something very similar to this when I was building a wizard in WPF. The way I went about doing it was by creating a class (let's say "MyPage") that simply extends page and adds the FileName property to it. Then, when you want to use MyPage, declare it in the XAML as such. This way your XAML will look like more or less like:

<mynamespace:MyPage 
    xmlns:mynamespace="clr-namespace:PathOfNamespace"
    FileName="MyFileName.file">
    <some more XAML>
</mynamespace:MyPage>
