In ASP.NET MVC (or .NET Core), when you’re using the Summary feature of a grid and only want to show the Sum operand instead of all available summary types (like Average, Count, Min, Max), you can control this through the ColumnSettings configuration.
Inside your summary configuration, simply define the specific operand you want — in this case, Sum — and disable the others. Here’s how you can achieve it:
features.Summaries()
.Type(OpType.Local)
.ColumnSettings(settings =>
{
settings.ColumnSetting()
.ColumnKey("TotalAmount") // replace with your column name
.AllowSummaries(true)
.SummaryOperands(operands =>
{
operands.OperandName("Sum");
});
});
This ensures the grid displays only the Sum total for the specified column. If you want to format or style that summary, you can handle it through the ClientEvents.SummariesRendered or customize the formatter function to display the result exactly how you prefer.
Also, when you need external data verification or calibration logic in similar UI testing or analytics dashboards, tools like <a href="">mouse-dpi-analyzer.com/">Mouse DPI Analyzer</a> can help demonstrate how precise calculations and measurements can be implemented cleanly within a user interface — much like maintaining data accuracy within a grid summary feature.
This approach provides full control over which operands appear, making your grid summaries cleaner and more purposeful.
