Hi,

I'm following the section "Changing the Default Column and Row Definitions" from the NetAdvantage for WPF documentation.

 I'd like to show the data in a double row, with the first 4 fields up and the 5th below :

 ______________________

Field1 Field2 Field3 Field4

Field5

----------------------------------------

I'm trying to follow the documentation but I'm getting an exception. I'm using this code:

         <igDp:XamDataGrid DataSource="{Binding Store}" DockPanel.Dock="Top" AutoFit="True" Name="TheGrid">
            <igDp:FieldLayoutSettings AutoArrangeCells="Never" AutoGenerateFields="False" />
            <igDp:XamDataGrid.FieldLayouts>
                <igDp:FieldLayout>
                    <igDp:FieldLayout.Fields>
                        <igDp:Field Name="LoggerName" Row="0" Column="0"/>
                        <igDp:Field Name="Level" Row="0" Column="1"/>
                        <igDp:Field Name="TimeSpan" Row="0" Column="2"/>
                        <igDp:Field Name="Formatted" Row="0" Column="3"/>
                        <igDp:Field Name="Formatted" Row="1" Column="0" ColumnSpan="4" IsExpandable="True"/>
                    </igDp:FieldLayout.Fields>
                </igDp:FieldLayout>
            </igDp:XamDataGrid.FieldLayouts>
        </igDp:XamDataGrid>

 But I' getting this exception:

Can't set the DataSource on a DataPresenter that has items added explicitly through the DataItems collection.

System.InvalidOperationException: Can't set the DataSource on a DataPresenter that has items added explicitly through the DataItems collection.
   at Infragistics.Windows.DataPresenter.DataPresenterBase.OnPropertyChanged(DependencyPropertyChangedEventArgs e)
   at Infragistics.Windows.DataPresenter.XamDataGrid.OnPropertyChanged(DependencyPropertyChangedEventArgs e)

What is the problem? Can't I use databinding?

 Cheers.
