To display only the Sum operand in the grid summary, you can adjust the summary settings to show just the final total, not each individual value. Update the summary configuration to exclude other operands and focus on Sum only. Here’s an example:

features.Summaries().Type(OpType.Local).ColumnSettings(settings => { settings.ColumnSetting().ColumnIndex(0).AllowSummaries(false); settings.ColumnSetting().ColumnIndex(1).SummaryOperands(SummaryOperand.Sum); });
