Data grid with 830 rows and 8 columns
Our Blazor Grid allows you to compute total and group summaries based on custom logic. To create a custom summary, declare a DxGridSummaryItem object in the TotalSummary or GroupSummary template and set the SummaryType property to Custom. Then, handle the Grid's CustomSummary event to implement the summary calculation algorithm. This event occurs multiple times as follows:
- Before grid rows are processed. The event argument's SummaryStage property value is Start. At this stage, you can initialize a summary value.
- For each data row in the processed range. The SummaryStage property value is Calculate. At this stage, you can calculate a summary value.
- After grid rows are processed. The SummaryStage property value is Finalize. At this stage, you can finalize summary calculation.
To refresh grid summary values, call the RefreshSummary method. You can also specify the DisplayText property or handle the CustomizeSummaryDisplayText event to customize the summary's display text.
In this demo, the custom summary calculates the sum of Total values against the selected Grid rows. The built-in total summary calculates the grand total for all rows.
