Example

Executing the example requires a form containing the DimensionTree component with the DimensionTree1 identifier, the UiDimension component with the UiDimension1 identifier and the Button component with the Button1 identifier. Determine the UiDimension1 component as data source for the DimensionTree1 component. Data source for the UiDimension1 component must be MDM table dictionary with set dynamic loading of elements.

The example is a handler of the OnClick event for the Button1 component.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Dim: IDynamicInstance;
    LastItemIndex: Integer;
Begin
    Dim := UiDimension1.DimInstance As IDynamicInstance;
    // Get index of the last dictionary element
    LastItemIndex := Dim.CreateDimElementArray.Count - 1;
    If Dim.IsLeafUnloaded(LastItemIndex) Then
        Debug.WriteLine("Index of the last element owner: " +
            Dim.OwnerOfUnloadedLeaf(LastItemIndex).ToString);
        Else
            Debug.WriteLine("Index of the last element owner: " +
                Dim.OwnerOfLoadedNode(LastItemIndex).ToString);
    End If;
End Sub Button1OnClick;

On clicking the Button1 button the console displays index of the element which is a parent towards the last element.
