Angular Data GridRow Grouping - Unbalanced GroupsEnterprise
This section covers Unbalanced Groups - when grouping by rows that can contain
undefined group values.
By default, unbalanced rows (rows containing
undefined or empty values for the column that is being grouped) get grouped together as
(Blanks). To instead have the nodes remain ungrouped, you can enable the
groupAllowUnbalanced grid option. We refer to this scenario as Unbalanced Groups in that there is a mix of groups and rows as siblings.
The following example demonstrates:
groupAllowUnbalancedgrid option has been set to
- Data is grouped by column 'State'. Rows are either grouped by state 'New York', 'California' or not grouped.
- Removing the grouping shows that the non grouped rows have no 'State' value.
The unbalanced group feature is not supported when using the Server SideRow Model (SSRM)
When not using unbalanced groups, the grid will, by default, create a (Blanks) group and populate it with any rows without a valid group value. The following example demonstrates this default behaviour:
