My dataGrid has a ObservableCollection as data source.

When i add a new item into collection, the total values in summary row does not updated!
There is screenshot in attach file.


My sfDataGrid :
<syncfusion:SfDataGrid Grid.Row="1"
                               x:Name="MainSfDataGrid"
                               ItemsSource="{Binding Path=TemporaryCollection,Mode=TwoWay}"
                               AllowGrouping="False" AllowResizingColumns="True" AllowRowHoverHighlighting="True"
                               AllowSelectionOnPointerPressed="True"
                               BorderBrush="{DynamicResource LightBlueAccentBrush}" AutoGenerateColumns="False"
                               RowHoverHighlightingBrush="{StaticResource LightOverlayBlueAccentBrush}"
                               Background="Transparent"
                               SelectedItem="{Binding Path=SelectedItem,Mode=TwoWay}">
            <syncfusion:SfDataGrid.Resources>
                <Style TargetType="syncfusion:GridHeaderCellControl">

                    <Setter Property="Background" Value="{DynamicResource LightBlueAccentBrush}" />
                </Style>
            </syncfusion:SfDataGrid.Resources>
            <syncfusion:SfDataGrid.Columns>
                <syncfusion:GridNumericColumn HeaderText="№" MappingName="RowNumber" NumberDecimalDigits="0"
                                              ColumnSizer="Auto" />
                <syncfusion:GridNumericColumn HeaderText="Article" MappingName="Article" NumberDecimalDigits="0"

                <syncfusion:GridTableSummaryRow  Title="Summary: {TotalSum} , {TotalQuantity} names." ShowSummaryInRow="True">
                    <syncfusion:GridTableSummaryRow.SummaryColumns>
                        <syncfusion:GridSummaryColumn Name="TotalSum"
                                                          Format="'{Sum:c}'"
                                                          MappingName="Sum"
                                                          SummaryType="DoubleAggregate" />
                        <syncfusion:GridSummaryColumn Name="TotalQuantity"
                                                          MappingName="RowNumber"
                                                          Format="'{Count:d}'"
                                                          SummaryType="CountAggregate" />
                    </syncfusion:GridTableSummaryRow.SummaryColumns>

Thanks for your advice, I set the property SfDataGrid.LiveDataUpdateMode to AllowSummaryUpdate , and now the summary row works correct!
