WPF DataGrid 'Refresh' is not allowed duri

I have the following grid

    <DataGrid

        x:Name="TablesDataGrid"
        Grid.Column="0"
        Grid.Row="1"
        ItemsSource="{Binding FilteredModels.View}"
        AlternationCount="2"
        AutoGenerateColumns="False"
        CanUserSortColumns="True"
        CanUserReorderColumns="False"
  CanUserDeleteRows="False"
  CanUserAddRows="False"
  SelectionMode="Extended"
        IsReadOnly="False"
  SelectionUnit="FullRow"
        RowHeight="25"
  HorizontalAlignment="Stretch"
  ColumnWidth="Auto">
            <DataGrid.Columns >
                <DataGridCheckBoxColumn Width="*" Binding="{Binding IsChecked, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"  IsReadOnly="False">
                    <DataGridCheckBoxColumn.HeaderTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.CheckAll}"/>
                        </DataTemplate>
                    </DataGridCheckBoxColumn.HeaderTemplate>
                </DataGridCheckBoxColumn>
                <DataGridTextColumn Header="Source Table" Binding="{Binding SourceTableFullName}" Width="4*"></DataGridTextColumn>
                <DataGridTextColumn Header="EDW Schema"  Binding="{Binding SchemaName}" Width="2*"></DataGridTextColumn>
                <DataGridTextColumn Header="EDW Table" Binding="{Binding TableName}" Width="4*"></DataGridTextColumn>
                <DataGridTextColumn Header="Status" Binding="{Binding Status}" Width="*"></DataGridTextColumn>
            </DataGrid.Columns>
        </DataGrid>

and then i have a seachCommand with performs the search on the collectionViewSource FilteredModels in the viewmodel and then calls

this.FilteredModels.View.Refresh();

when a user checks a few of the checkboxes and sends the grid into editmode and then performs a search we get the following error

WPF DataGrid 'Refresh' is not allowed during an AddNew or EditItem transaction

is there a way to force the grid out of edit mode when a check box is checked or maybe even when the seach button is clicked or some other fix for this?

thanks!

I know its too late to answer...but for someone who is looking for answer

use cancelEdit or commitEdit method two times in a sequence like this

//for commit

this.datagrid_layers.CommitEdit();
this.datagrid_layers.CommitEdit();

//for cancel

this.datagrid_layers.CancelEdit();
this.datagrid_layers.CancelEdit();

you should be able to cast the selected item to IEditableObject and call EndEdit on it, or call the grids CancelEdit method.
