Hi Brian,

You can create a style for the SummaryRowCellControl and remove the TextBlock element that is responsible for the "=" symbol :

    <Style TargetType="igPrim:SummaryRowCellControl"  x:Key="CustomSummaryStyle">
        ....
        <Setter Property="SummaryDisplayTemplate">
            <Setter.Value>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
                        <TextBlock Text="{Binding SummaryDefinition.SummaryOperand.RowDisplayLabel}" />
                        <!--Remove this element-->
                        <!--<TextBlock Text=" = "/>-->
                        <TextBlock Text="{Binding Converter={StaticResource SDFormatStringConverter}}"/>
                    </StackPanel>
                </DataTemplate>
            </Setter.Value>
        </Setter>
       ... 
    </Style>

Then you can easily set this style in the SummaryRowSettings :

<igGrid:XamWebGrid.SummaryRowSettings>
                <igGrid:SummaryRowSettings AllowSummaryRow="Bottom"
                                                               Style="{StaticResource CustomSummaryStyle}"/>
 </igGrid:XamWebGrid.SummaryRowSettings>

Let me know if you have any questions.
