Syncfusion.Grouping Namespace : ChildTable Class

ChildTable Class

Defines a class for ChildTable which is either a TopLevelGroup or a group that can be referenced as nested table from a record in a parent table. ChildTable groups are created for every new key found based on RelationDescriptor.RelationKeys.

You can get access to a ChildTable through the NestedTable.ChildTable property of a NestedTable in a record.

A ChildTable defines a group of records that belong to a category specified with RelationDescriptor.RelationKeys. ChildTables are created similar to regular groups when the records of the table are categorized or when a new record is inserted. The collection in the TableDescriptor that defines categorization is the TableDescriptor.RelationChildColumns collection. RelationChildColumns will be added when there is a parent-child relation between two tables. The child table of such relation must be sorted by the columns that are used to identify a record. These columns match the foreign key columns of the parent table. For every new category key with regards to RelationChildColumns a ChildTable is created. The ChildTable class is derived from Group.

A child table can either be a final node with records or it can be a node with nested groups. If a group has records, its Group.Groups collection will be empty and the Group.Records collection will contain all records. If a group has nested groups, its Group collection will have the nested groups and the Group.Records collection will be empty.

A child table can be expanded and collapsed with its Group.IsExpanded property. Expansion of child tables will show or hide nested elements of the group within the Table.DisplayElements and Table.NestedDisplayElements collection.

A table has at least one child table. The Table.TopLevelGroup is a ChildTable which is derived from Group.
