Hi,
using XamDataGrid I get the following error: "Recursive call to Automation Peer API is not valid"
What I can say at the moment is, that this happens only on some Win XP machines.
What I do is the following:
During runtime I add a new tab to XamTabControl. The content of that tab is a view containing a XamDataGrid.

As a workaround I had to do 2 things:
1. Create an own control inheriting from XamDataGrid:
public class DataGridNonAutomation : XamDataGrid { protected override AutomationPeer OnCreateAutomationPeer() { return new EmptyAutomationPeer(this); } }
public class EmptyAutomationPeer : FrameworkElementAutomationPeer { public EmptyAutomationPeer(FrameworkElement owner) : base(owner) { } protected override List<AutomationPeer> GetChildrenCore() { return new List<AutomationPeer>(); } }
2. Remove the following FieldSetting: AllowRecordFiltering="True"
Here's the resulting XAML:
<controls:DataGridNonAutomation x:Name="PropertyGrid" DataSource="{Binding DocumentData}" Theme="Office2k7Black" GroupByAreaLocation="AboveDataArea" ScrollingMode="Immediate"> <controls:DataGridNonAutomation.FieldLayouts> <igDP:FieldLayout> <igDP:Field Name="Caption" Visibility="Visible" Width="220" Label="Bezeichnung" Localization.Attributes="Label(Text Readable Modifiable)"/> <igDP:Field Name="Value" Visibility="Visible" Width="*" Label="Wert" Localization.Attributes="Label(Text Readable Modifiable)"/> <igDP:Field Name="Group" Visibility="Visible" Width="*" Label="Gruppe" Localization.Attributes="Label(Text Readable Modifiable)"/> <igDP:FieldLayout.SortedFields> <igDP:FieldSortDescription IsGroupBy="True" Direction="Ascending" FieldName="Group" /> igDP:FieldLayout.SortedFields> </igDP:FieldLayout> </controls:DataGridNonAutomation.FieldLayouts> <controls:DataGridNonAutomation.FieldSettings> <igDP:FieldSettings AllowEdit="False" CellClickAction="SelectRecord" AllowGroupBy="True" CellVisibilityWhenGrouped="Collapsed" /> <controls:DataGridNonAutomation.FieldSettings> <controls:DataGridNonAutomation.FieldLayoutSettings> <igDP:FieldLayoutSettings HighlightAlternateRecords="False" AllowDelete="False" HeaderPlacementInGroupBy="OnTopOnly"/> </controls:DataGridNonAutomation.FieldLayoutSettings></controls:DataGridNonAutomation>
This works but I want the RecordFiltering working and don't want to have to override some or all controls to be able to override OnCreateAutomationPeer().
Maybe the post http://stackoverflow.com/questions/4017786/wpf-recursive-call-to-automation-peer-api-is-not-valid could gives a hint describing a problem with a combobox withing the grid.The record filter uses a XamComboBox...
Please have a look at it and give me a short feedback what to do.Sorry, but I can't give a small example project for reproducing the error. But maybe the stacktrace helps.

Hello,
I have logged this with development under ID: 122852 and I have also created a support ticket on your behalf: CAS-100277-H1G1Z6 and have linked the development issue to it, so that you can get automatically updated, when a Service Release containing the fix is available for download. You can get the new version from our website’s “My IG”, “My Keys & Downloads” tags: https://ko.infragistics.com/Membership/Default.aspx?panel=Downloads#Downloads
You can also monitor the support ticket’s progress through the “My Support Activity” tag: https://ko.infragistics.com/Membership/MySupport.aspx
Sorry for the delay!
The problem still exists. As I already wrote, I can't give a sample for reproducing the problem.
I can't give you more info than I wrote above. Sorry.
I am just checking the progress of this issue and was wondering if you managed to achieve your goal or if you need any further assistance on the matter.
As I said without an isolated sample project, where the issue is reproduced, I am not able to conclude what could be the reason for your behavior, because this is not a known issue. If you could send me such sample I will be able to investigate this further for you.
Hi Stefan,
I had a look at your links but no hint worked.
I cannot see that we have a bug in our code because in the stacktrace, our last action is to set the focus to a TabItemEx (System.Windows.UIElement.Focus()).
From that point only calls on Infragistic and Microsoft components are listed.
Any ideas?
