GridExportCustomizeCellEventArgs.SummaryItem Property

Returns information on the summary calculated in the cell currently being processed.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public ExportSummaryItem SummaryItem { get; set; }

Property Value

Type	Description
ExportSummaryItem	An object that contains information on the summary item or null if the processed cell does not belong to a group of total footer.

Remarks

The CustomizeCell action allows you to customize a cell in the exported file. You can use the AreaType property to determine where the processed cell is placed.

When a footer row’s cell is being processed (the AreaType property returns the GroupFooter or TotalFooter value), use the SummaryItem property to get information about a summary item contained in the cell.

If the current cell does not belong to a footer row, the SummaryItem property returns null.
