Cannot populate XAML items in control that is contained within another control

RyanCoodey — Sun, 12 Sep 2010 15:50:41 GMT

I have a template control Bookmark (not the one from the ESRI toolkit), and in MainWindow.xaml, this works just fine:

<sdl:Bookmark>
    <sdl:Bookmark.Bookmarks>
        <sdl:BookmarkItem Name="test" Extent="-121.89,33.60,-117.09,36.32">
        </sdl:BookmarkItem>
    </sdl:Bookmark.Bookmarks>
</sdl:Bookmark>

But, I also have a template control Titlebar which inside of its XAML contains one of these Bookmark controls, and in MainWindow.xaml, this does NOT work:

<sdl:Titlebar x:Name="Titlebar">
    <sdl:Titlebar.Bookmark>
        <sdl:Bookmark.Bookmarks> <!-- Doesn't like this -->
            <sdl:BookmarkItem Name="test" Extent="-121.89,33.60,-117.09,36.32">
            </sdl:BookmarkItem>
        </sdl:Bookmark.Bookmarks>
    </sdl:Titlebar.Bookmark>
</sdl:Titlebar>

I get this error:

Error 11 The tag 'Bookmark.Bookmarks' does not exist in XML namespace 'clr-namespace:SDL.ArcGIS.Client.Toolkit;assembly=SDL.ArcGIS.Client.Toolkit'. Line 45 Position 22. C:\Projects\SDL.ArcGIS.Client.Toolkit\SDL.ArcGIS.Client.Toolkit.WPFTestApplication\MainWindow.xaml 45 22 SDL.ArcGIS.Client.Toolkit.WPFTestApplication

Bookmark does have a member property in the Titlebar class that is set to the template bookmark in OnApplyTemplate(). I tried making a dependency property for the Bookmark property too, but that didn't help either.

Is this a Known limitation? Or most likley, what am I doing wrong?

Thanks a lot for any help!!!

*EDIT - Additional info:
Also, when doing the following, it compiles and launchs without error, but the BookmarkItems never appear in the ObservableCollection:

<sdl:Titlebar x:Name="Titlebar">
    <sdl:Titlebar.Bookmark>
        <sdl:Bookmark>
            <sdl:Bookmark.Bookmarks>
                <sdl:BookmarkItem Name="test" Extent="-121.89,33.60,-117.09,36.32">
                </sdl:BookmarkItem>
            </sdl:Bookmark.Bookmarks>
        </sdl:Bookmark>
    </sdl:Titlebar.Bookmark>
</sdl:Titlebar>

Even though it compiles, this doesn't seem right to me though... having to redeclare the Bookmark. It feels like a bookmark is being created inside a bookmark.

I'm guessing you need a collection type declared around the sdl:BoorkmarkItem (of whatever type Bookmark.Bookmarks
is). Something like (assuming the type is BookmarkItemCollection):
<sdl:BookmarkItemCollection>
<sdl:BookmarkItem Name="test" Extent="-121.89,33.60,-117.09,36.32" />
</sdl:BookmarkItemCollection>

of whatever type Bookmark.Bookmarks
is)

Bookmark.Bookmarks is an ObservableCollection<BookmarkItem>...

hmm, i know there are issues with ObservableCollection in xaml, not sure how to use it... I tried making it a List too, but still not sure...

Thanks
