    Having the same issue -- this crashes our WPF app hard, making it unusable.  Were you able to find a workaround?

     

    Edit: This was reproduced on 32-bit Vista SP1, running .NET 3.5 SP1,  Infragistics 8.2 Express.

    Sourcecode and steps to reproduce:

    Window1.xaml:

    <Window x:Class="TestTabControl.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:DataPresenter="clr-namespace:Infragistics.Windows.DataPresenter;assembly=Infragistics3.Wpf.DataPresenter.v8.2"
        Title="Window1" Height="1000" Width="1000" x:Name="Root">
        <Grid>
            <TabControl>
                <TabItem Header="Tab2">              
                </TabItem>
                <TabItem Header="Tab1">
                    <DataPresenter:XamDataGrid x:Name="Grid1"  DataSource="{Binding List1,ElementName=Root}">
                        <DataPresenter:XamDataGrid.FieldLayoutSettings>
                            <DataPresenter:FieldLayoutSettings AutoGenerateFields="False" AllowAddNew="True">                        </DataPresenter:FieldLayoutSettings>                       
                        </DataPresenter:XamDataGrid.FieldLayoutSettings>
                        <DataPresenter:XamDataGrid.FieldLayouts>
                            <DataPresenter:FieldLayout >
                                <DataPresenter:FieldLayout.FieldSettings>
                                    <DataPresenter:FieldSettings />
                                </DataPresenter:FieldLayout.FieldSettings>
                                <DataPresenter:FieldLayout.Fields>
                                    <DataPresenter:Field Name="Name"></DataPresenter:Field>
                                    <DataPresenter:Field Name="Email"></DataPresenter:Field>
                                </DataPresenter:FieldLayout.Fields>
                            </DataPresenter:FieldLayout>
                        </DataPresenter:XamDataGrid.FieldLayouts>
                    </DataPresenter:XamDataGrid>
                </TabItem>           
            </TabControl>
        </Grid>
    </Window>

    Window1.xaml.cs: 

    namespace TestTabControl
    {
        public partial class Window1 : Window
        {
            private BindingList<TestObject> list1 = new BindingList<TestObject>();
            public BindingList<TestObject> List1
            {
                get { return list1; }
                set { list1 = value; }
            }

            public Window1()
            {
                list1.Add(new TestObject() { Name = "my name", Email = "my email" });
               
                InitializeComponent();
            }

            public class TestObject
            {
                public string Name { get; set; }
                public string Email { get; set; }
            }
        }
    }

    And the steps:

    1. Click in the addNewRecord Row, write a new name, but, do not press enter! Instead click on the empty tab ( tab2 ).

    2. Click again on the first tab, Tab1, all rows have suddenly dissapeared !?

    3. Click in the addNewRecord Row, write a new name this time press enter. the new row moves up in the grid.

    4. Click the other tab again ( Tab2 ) -> The Application crashes.

    I'm using windows xp, .net 3.5 SP1, and infragistics version 8.2
