Element is already the child of another elementint. RRS feed

  • Question

  •  Hi, I am hoping someone can help me.

     I am trying to create a JIT collection.  I have successfully generated the cxml file and the test page looks ok.  When I try to load in the PivotViewer I am receiving this error:

    Microsoft JScript runtime error: Unhandled Error in Silverlight Application
    Code: 4009   
    Category: ManagedRuntimeError      
    Message: Element is already the child of another element.  

    If I click Ignore I see this:

    throw new Error("Unhandled Error in Silverlight Application MeasureOverride of element 'Microsoft.Pivot.Internal.Controls.SeahorseItemVirtualizingPanel' should not return PositiveInfinity or NaN as its DesiredSize.");

    Other collections in the JIT sample are working so I'm trying to figure out the issue.

    The cxml I'm generating is:

    <Collection xmlns="http://schemas.microsoft.com/collection/metadata/2009" xmlns:ui="http://schemas.microsoft.com/livelabs/pivot/collection/2009" SchemaVersion="1" Name="People">

  • After installing the silverlight 4 toolkit, make sure you clean & rebuild the Visual Studio 2010 solution. This is because Visual Studio doesn't see any of the source inputs changed (the only change is you've installed some DLLs that are useful to include in the silverlight XAP pack, so it won't *automatically* rebuild)

    IF you've already done this, and it still doesn't work, try making a copy of the .XAP file and rename to a .ZIP file (.XAP is really just a .ZIP file containing the binaries for the application), then unpack the resulting .ZIP and post the list of files here as well as the contents of the manifest, that might help.

  • May not be related but i have seen an error like this in the past when adding and removing child controls from an app on the fly.

    in my case it did have to do with the x:Name of the child controls not beeing set on each child.

    see if that might be happening here, check every control on the page that is in the xaml that starts and check that the collection is getting valid different names.

  • PivotControlViewer should be contained in an element that has width of "*", Auto width might not work.

    to rule out this issue

    I would try removing all the xaml from the page and just have something like this in the page and see




    BTW, Did you write custom code for generating, or using the library from the sample source?

  • Make sure you have the very latest Silverlight Tools nad SDK libraries from, I think, April 2010. I had a very similar error before updating them - now it's fixed.

  • I'm having the same issue with a very simple app:
    <UserControl x:Class="Ag.MainPage"
        d:DesignHeight="300" d:DesignWidth="400">
        <Grid x:Name="LayoutRoot" Background="White">
            <pivot:PivotViewer x:Name="PivotViewer" />

    Here is what I can see from windbg... any chance someone on the Pivot team can take a look and see if something is obviously wrong here? It doesn't look like silverlight has started loading my code yet.

  • Boxout6,

    Can you also post the contents of the DZC you are generating? I suspect something is invalid there, and causing the problem, although I've tried a couple ideas of invalid DZC contents to try and repro this, and so far I can't. At least if it all looks good, we can rule that out.

  •  I use the latest version of pivot, toolkit, and create a very simple project (just contains only one pivot control in xaml file), but this error still there.

    Saturday, July 3, 2010 7:44 AM
  • Same problem here - in my own testproject and in the provided PivotViewerSample.
    Saturday, July 3, 2010 8:29 AM
  •  Ok - reinstalled the latest silverlight toolkit (http://silverlight.codeplex.com/releases/view/43528) and everything works fine now.

    Saturday, July 3, 2010 9:01 AM
  •  Uninstall and reinstall again (after download the latest version of toolkit), the error still exist. Anyone help me...

    Saturday, July 3, 2010 10:54 AM
  • dqminh,

    Sorry to have to ask but I have to make sure, because there is a lot of confusion between Silverlight 4 *Tools* for Visual Studio 2010 (which adds VS extensions to work with silverlight 4), and Silvelright 4 *Toolkit* (which provides a bunch of silverlight libraries that you can use to get extra controls).

    If you are still having problems, even with the sample, I have to ask to make sure there wasn't some confusion in what you installed/reinstalled...

    If not, let me know. We'll keep working on this till we figure it out.

  •  To Andrew,

    I follow the instruction in Troubleshooting.txt (can be found in Pivot_JIT_Sample.zip):


    Visual Studio 2010 (includes the .NET 4.0 framework)

    Microsoft Silverlight 4 Tools for Visual Studio 2010

    Silverlight Toolkit

    Silverlight Developer Tools

    So, I have Visual Studio 2010 Utimate, I download Microsoft Silverlight 4 Tools for Visual Studio 2010 (Silverlight4_Tools.exe), Silverlight Toolkit (Silverlight_4_Toolkit_April_2010.msi) and Silverlight Developer Tools (Silverlight_Developer.exe).

     What am I wrong?

    Saturday, July 3, 2010 10:42 PM
  •  Dear Andrew,

    Your sample run smoothly in Windows 7 64 bit, but cannot run in Windows 7 32 bit (error Element is already the child of another element.)

    Please help me.

    Monday, July 5, 2010 12:13 AM
  • After installing the silverlight 4 toolkit, make sure you clean & rebuild the Visual Studio 2010 solution. This is because Visual Studio doesn't see any of the source inputs changed (the only change is you've installed some DLLs that are useful to include in the silverlight XAP pack, so it won't *automatically* rebuild)

    IF you've already done this, and it still doesn't work, try making a copy of the .XAP file and rename to a .ZIP file (.XAP is really just a .ZIP file containing the binaries for the application), then unpack the resulting .ZIP and post the list of files here as well as the contents of the manifest, that might help.

  • I tried everything but no.

    Finally I gave up and made another project, this time including the Host Asp.NET Web App in the beginning.

    That helped.

  • I just had this same error message (Element is already the child of another element) but is was the result of a different cause and I thought I'd share the solution in case anyone else runs into the same issue...

    In my .cxml file I had the p:BrandImage attibute set to a url that returned an HTTP 403 error. Every time I viewed my cxml file in the SL pivot control I would show this error message, I'd click ok, and the pivot viewer would show everything perfectly fine from there on out. The same cxml file would load without error in the MS Live Labs Pivot app.

    If anyone from the Pivot team is reading, it looks like some better error messages is needed.

  • Hi,

    As far as I can see the main reason for this is the duplicate nodes in the cxml file.

    I got the same error. When I changed to another file issue got fixed.

  • I had the same issue and found the answer in this blog post


    The problem was some missing references (I believe if there is any problem with installation of the Silverlight Toolkit they won't be included in the zap file automatically).   A reinstall of the Toolkit may help but certainly manually making the right dll references solved the problem.

    This is good.

  • @Timmy G: thank you!!!!

    My pivotviewer app worked fine locally in visual studio, but not when deployed to iis. I also got the "Element is already the child of another element" error.

    It turned out that when deployed to iis, the relative path to the images I used to fill a Facet was wrong. It could not load the images.

    Thanks again! You saved me hours of searching and frustration! :-)
