Hello,

I have a WebDataGrid in an UpdatePanel. If I select a row and this fires a RowSelectionChanged event the CustomSummary in the SummaryRow disappears (the cell is empty then).
If I add standard column summaries they stay, only custom summaries are lost (also with EnableViewState="true").

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
 <ContentTemplate>
  <ig:WebDataGrid ID="wdg1" runat="server" EnableAjax="false" EnableDataViewState="true">
                            <Behaviors>
                                <ig:Selection CellClickAction="Row" RowSelectType="Single">
                                    <AutoPostBackFlags RowSelectionChanged="true" />
                                </ig:Selection>
                                <ig:SummaryRow ShowSummariesButtons="False" FormatString="{1}" CompactRendering="On" EmptyFooterText="" Enabled="true">
                                    <ColumnSummaries>
                                        <ig:ColumnSummaryInfo ColumnKey="Avg1">
                                            <Summaries>
                                                <ig:Summary SummaryType="Custom" CustomSummaryName="Avg1" />
                                            </Summaries>
                                        </ig:ColumnSummaryInfo>
                                    </ColumnSummaries>
                                    <ColumnSettings>
                                        <ig:SummaryRowSetting ColumnKey="Avg1" ShowSummaryButton="false">
                                            <SummarySettings>
                                            <ig:SummarySetting SummaryType="Custom" CustomSummaryName= "Avg1" FormatString="{1:##.#0}" />
                                            </SummarySettings>
                                        </ig:SummaryRowSetting>
                                    </ColumnSettings>
                                </ig:SummaryRow>
                            </Behaviors>
                        </ig:WebDataGrid>
                    </ContentTemplate>
                    <Triggers>
                        <asp:AsyncPostBackTrigger ControlID="butUpdate" EventName="Click" />
                    </Triggers>
</asp:UpdatePanel>
