Hinweise
The Parent element is used to create a recursive hierarchy. A recursive hierarchy can be created from a set of data that contains fields that refer to other fields in the same set of data. For example, a table containing a list of employees may contain both an employee ID and a manager ID. By grouping the data by employee ID and identifying the manager ID as the parent, you can create a hierarchy of employees.
The expression within the Parent element evaluates to a variant. Parent can only be used in groups with a single group expression.
Beispiel
The following example illustrates the use of the Parent element to produce a recursive hierarchy of employees. The table details are set to group on the EmployeeID field, and the parent is set to the ManagerID field.
<Grouping Name="Table1_DetailsGroup">
<GroupExpressions>
<GroupExpression>=Fields!EmployeeID.Value</GroupExpression>
</GroupExpressions>
<Parent>=Fields!ManagerID.Value</Parent>
<Grouping>
