Parent Property (Grouping)

In This Topic

Gets or sets an expression that identifies the parent group in a recursive hierarchy.

Syntax

'Declaration
 
Public Property Parent As ExpressionInfo

public ExpressionInfo Parent {get; set;}

An GrapeCity.Enterprise.Data.Expressions.ExpressionInfo object containing the parent group in a recursive hierarchy.

Remarks

This property only applies if the group has exactly one group expression

Indicates the following:

Groups are sorted according to the recursive hierarchy (sort is still used to sort peer groups).
Labels (in the document map) are indented according to the recursive hierarchy.
Intra-group show/hide toggles items according to the recursive hierarchy (see ToggleItem).

If filters on the group eliminate the parent of a group instance, it is instead treated as a child of the parent's parent.

Example

Grouping group = new Grouping();
group.Parent = ExpressionInfo.FromString("=Fields!ParentCategory.Value");
