Property Value

Type	Description
RenderFragment	A collection of group summary items (UI fragment) that the browser renders in the grid’s markup.

Remarks

The DxGrid calculates group summary values across all records in a group. To create the group summary, declare a DxGridSummaryItem object in the GroupSummary template, and specify the SummaryType and FieldName properties.

You can set the SummaryType property to Custom and handle the CustomSummary event to create a custom summary item.

The Grid displays summary values in the group row after the group header. To show the summary value in the group footer, set the FooterColumnName property to the target column’s name.
