RadGridView exception on ReorderColumn/DragColumn in PanelGroup

[Rares Vasilescu]

Hi,

I have encountered the following error when I was trying to reorder column or drag it in panel group.

assembly: Telerik.Windows.Controls.GridView.dll, version: 2010.1.326.35
ExceptionMessage:
Root AdornerLayer Not Found. Please make sure that your root visual is Window or other element that has an adorner layer. Alternatively, wrap your root panel in an <AdornerDecorator> element.

Argghh.  I just discovered I am getting this same error now after I purchased the licensed version.  I rolled back the code to use the demo version of RAD controls and it worked fine, but not using the latest version (2010.1.422.35).

How do you suggest one goes about narrowing down what the issue is?

[Tsvyatko]

Hello Christopher Hujanen,

The issue we have encountered and investigated is related to applications in which the GridView is added within Page (not in Window). The core problem is related to the fact that the root visual element in Page element does not have its Adorner Layer which is essential part of the Drag and Drop mechanism.

Currently, I can suggest as workaround to add the missing Adorner Layer on Page load. It has one specific that need to kept in mind, doing it will call the Page Load Event twice. Please check the attached project as reference.

If the case in which the problem occurs does not include Page element, please sent us some additional information regarding your scenario.

Best wishes,

Tsvyatko

The problem I am seeing is when the gridview is on a usercontrol (or a "view" which is derived from a usercontrol).  I've attached a screenshot with also a Snoop dump of the visual tree to hopefully help you find out where the problem is.

Here is the XAML for that "usercontrol":

<my:ViewBase x:Class="MyApp.Contacts.ContactsView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:MyApp.Contacts"
             xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
             xmlns:Controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="500"
             d:DataContext="{d:DesignInstance local:ContactsDesignerViewModel, IsDesignTimeCreatable=True}">
    <Grid>
        <telerik:RadGridView ItemsSource="{Binding Contacts}" Controls:StyleManager.Theme="Office_Blue"
                             AutoGenerateColumns="False" CanUserFreezeColumns="False" IsReadOnly="True"
                             ColumnWidth="*" SelectedItem="{Binding SelectedContact}" MouseDoubleClick="RadGridView_MouseDoubleClick">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Group" DataMemberBinding="{Binding Company.Group.Name}" />
                <telerik:GridViewDataColumn Header="First Name" DataMemberBinding="{Binding Person.FirstName}" />
                <telerik:GridViewDataColumn Header="Last Name" DataMemberBinding="{Binding Person.LastName}" />
                <telerik:GridViewDataColumn Header="Created" DataMemberBinding="{Binding CreatedOn}" />

            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

     </Grid>
</my:ViewBase>

Hello Christopher Hujanen,

Can you also post the root elements of the visual tree? Also, could you please share with us the XAML code including custom style if there are any in order to determine the exact cause of the problem and provide solution.

We have the same adorner-problems when using the grouping function.
Using the "old" version of Telerik everything was ok.

After changing to the new april-dll's this problem came up.

We also get this, when opening the xaml for the window:

System.IO.FileLoadException

Could not load file or assembly 'Telerik.Windows.Controls.GridView, Version=2010.1.422.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

...

An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

Hi Guys,
I experience the same problem with this error message.
All I have to do is rapidly click on a column header for some time and it will work the first few times doing the sorting, but eventually will crash with this error.

2010.1.422.35 Assembly Version.



//Graham.

[Graham]

Ok, problem is still there.  I can trigger this problem on gridviews and also on RadScheduler.  If you attempt to drag an appointment on RadScheduler it will crash with this 'adornerlayer not found' error.

Using Latest Dev Build - 2010.1.430.35

In the last RadControls WPF for 2009 none of these problems existed.  I'm only upgrading due to some strange display bug with the height of radWindows getting cut-off in the 2009 version - that bug appears to have been fixed in the 2010 version, but more serious bugs are in the latest version it would seem. 

Does anybody have a workaround for this error?

[Maya]

Hello Graham,

The problem occurs when there is a custom structure in your applications. The Adorner Layer is the one that provides the Drag and Drop functionality and it is not always available depending on the Root Element. 

The workaround proposed by Tsvyatko in a previous post here is applicable for almost every context. In case it does not solve the problem in yours projects, please send us a project via support ticket or post you xaml code here so that we can provide you with a better solution.

Graham -- I also had the exact same problem with RadScheduler.  I followed the suggestion about adding an AdornerLayer but it didn't resolve the issue for me.

I will post some more details of what my visual tree looks like for analysis later today.

[Christopher Hujanen]

I've attached a more complete screenshot of the visual tree using the WPF debug visualizer.  There is an AdornerLayer in there, but it looks like it's not in the right spot (highlighted).

Hope that helps!

[Graham]

Hi Chris & Maya,

I have a RadGridViews in UserControls and also and experience the error.  The workaround does not work for UserControls as the solution provided by Tsvyatko is for Pages only.

I would just go back to the 2009 version, but there is an issue with the height of RadWindows on some resolutions - especially widescreen resolutions - where the bottom of the RadWindow is cropped off.  It only happens at some resolutions but unfortunately for me, that's not good enough for my client.  I am in a bit of a bind as to fix that RadWindow problem I need to upgrade to 2010, but in doing so it breaks both the Scheduler and the RadGridView with this Adorner problem.

[Calin Calin]

Hi,

I am having the exact same problem. Is there a deadline on the fix, I can't use the page load approach to many places a grid gets loaded.

Thank you,

[Alex Martinez]

I have the same problem within a RadScheduler inside a UserControl. I can't Drag&Drop appointments.
Anybody found a solution?

[Christopher Hujanen]

The only solution I know of so far is to roll back to one of the 2009 releases.  It seems to have been broken in the 2010 release.

Maya/Tsvyatko -- Any updates on the Telerik side?  

[Tsvyatko]

Hello Christopher Hujanen,

Currently, we are working on the solution on this issue and it will be included in one of our next internal builds. The main problem is related to the fact that when drag and drop is performed it look for adorner layer of the root panel. In structures such as custom Windows (e.g. ribbon windows), this layer might not be present and thus the drag cannot be performed. In such cases possible workaround is to inject such layer in the tree structure wrapping the top-most panel.

Please excuse us for the inconvenience caused. We will keep you posted on the progress on this issue.

Kind regards,

Thank you for the fix, it works great !

Your product is getting better and better.

[Alex Martinez]

It's correct! The build "2010.1.0515.35" works perfectly :)

[Rieni De Rijke]

Thank you for the update. We are pleased with the fixes and features, but...
Selecting rows with use of the key.up and key.down only works when SelectionMode="Single".
It no longer works with SelectionMode="Extended" or SelectionMode="Multiple" like in the prior versions.
Is there a new property or something that should be set?

[Milan]

Hello Rieni De Rijke,

The selection issues were fixed and the functionality should be back to normal with our latest build 2010.1.0521.35.

Sorry for the inconvenience.

All the best,
Milan
