Vista - Inheriting from custom made page in xaml

How can I inherit from my custom made page?



Example:

I have a page baseclass in my 1st assembly:

<Page x:Class="Common.WinFX.Pages.DetailPage"

xmlns="http://schemas.microsoft.com/winfx/avalon/2005"

xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"

Title="DetailPage"

>

<Grid>

<Label>Test</Label>

</Grid>

</Page>



How can I inherit a new page (in another assembly)?

If I do this:

<DetailPage x:Class="Contact.WinFX.ContactPersonDetail"

xmlns="http://schemas.microsoft.com/winfx/avalon/2005"

xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"

Title="ContactPersonDetail"

>

<Grid>



</Grid>

</DetailPage>



I get an error stating that the DetailPage is an unknown tag.

I'm "using" the 1st assembly. Do I need to make some xml tag?

Okay, I cracked the namespace part, but then I got:
"Error 25 Common.WinFX.Pages.DetailPage cannot be the root of a XAML file
because it was defined using XAML."

Can this be try? That seems like a wierd limitation?

Yes that is a by design limitation for v1.

If we do enable this in the future, how would you like the content of the
first page to work in the subclassed page?
We'd like to understand your scenario.

Today, you can make the base class in a programming language and then build
the subclasses with markup.

Hi Roy,



Thanks for your reply.

We are developing a full blown "normal" Windows application in WinFX, so we
are going to have a lot of pages for viewing for example details for
customers, equipment, locations and so forth.



I'm still fondling around in blind. But my idea was to design a base class
for detail pages, with the look, feel and commands we would prefer, and then
derive and specialize the individual pages.

I am not sure how it would handle the content; I was hoping to see how you
managed that But I was expecting that I could see the base class in the
designer and then build on that like a normal Windows form.



But it's okay. I got it working with a "coded" base class, so I can
certainly live with that.

Rob,

My attempts so far to define a page or in my case a window with a base class
other than the WPF class have failed. It complains that the generated .g.cs
partial class has a different base class than my code behind partial class.
Can you point me at a sample that does this?

Michael

Hi Michael,

Here is how I did mine:
_________
1st file DetailPageBase.cs:
---
using System;
using System.Collections.Generic;
using System.Text;

namespace Common.WinFX.Pages
{
public class DetailPageBase: System.Windows.Controls.Page
{
}
}
_________
2nd file ContactPersonDetail.xaml:
---
<?Mapping XmlNamespace="Local" ClrNamespace="Common.WinFX.Pages"
Assembly="Common.WinFX" ?>
<LocaletailPageBase x:Class="Contact.WinFX.ContactPersonDetail"
xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
Title="ContactPersonDetail"
xmlns:Local="Local">
<Grid>
</Grid>
</LocaletailPageBase>
_________
3rd file ContactPersonDetail.xaml.cs:
---
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Common.WinFX.Pages;

namespace Contact.WinFX
{
/// <summary>
/// Interaction logic for ContactPersonDetail.xaml
/// </summary>

public partial class ContactPersonDetail : DetailPageBase
{
public ContactPersonDetail()
{
InitializeComponent();
}
}
}

Hope you can figure out the example.

Thanks,

I will give that a try when I get a chance. Your example was very clear.
