Expand(Node: Integer; [Recursively: Boolean = false ]);
Node. Node, which children hierarchy is collapsed.
Recursively. It determines whether children hierarchy is recursively expanded.
The Expand method expands hierarchies of tree children for the specified node.
Available values of the Recursively parameter:
True. The entire hierarchy of all children is expanded.
Flase. Hierarchy of the selected element is expanded.
To collapse hierarchy of tree children of the specified node, use the IDimensionViewerBase.Collapse method.
To determine the level of dimension that is automatically expanded on opening a drop-down component area, use the IDimensionViewerBase.AutoExpandDepth property.
Executing the example requires a form with the Button1 button and the MetaAttributesBreadcrumb component named MetaAttributesBreadcrumb1. MetaAttributesBreadcrumb1 is connected to a time series database.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
DV: IDimensionViewerBase;
Begin
DV := MetaAttributesBreadcrumb1.DimensionViewer;
//Expand children hierarchy
DV.Expand(0, True);
End Sub Button1OnClick;
Clicking the button in the drop-down list of the MetaAtrributesBreadCrumb1 component the child elements hierarchy is collapsed at the element with the 0 index.
