Remarks
The AllowPartialGroups property allows you to save screen space by hiding those group rows that contain a single data row. In these cases, the data rows will be displayed in place of group rows.
When the AllowPartialGroups mode is enabled, the following takes place.
- Unique data groups are separated with blue lines. Blue line separators are also used in certain other cases (e.g., to separate preview sections, a bottom new item row, etc.).
- Grouped column headers are displayed in the Group Panel and Column Header Panel simultaneously (regardless of the GridOptionsView.ShowGroupedColumns setting).
If the GridOptionsBehavior.AlignGroupSummaryInGroupRow option is set to Default or True, all group summaries (even those that are positioned in group footers) are forcibly displayed in group rows under the corresponding column headers, and group footers are hidden. This applies only to non-hidden group rows.
If the GridOptionsBehavior.AllowFixedGroups option is enabled, the AllowPartialGroups property is not in effect and group rows are never hidden.
Note
In AllowPartialGroups mode, data grouping by multiple columns is not supported.
