The Tree View can be subordinate to other filtering elements, or be the main filtering element for them. The Tree View can work in two selection modes:

One. In the viewer, you can select only one value within one level of the hierarchy of values. Accordingly, data filtering for the elements of the dashboard will be performed only by one value.

Multi. In the viewer, you can select multiple values within the same level of the hierarchy of values. Accordingly, data filtering for the elements of the dashboard will be performed by all selected values.

You may setup the Tree View element in the editor. To call the editor, you should do the following in the report designer:

Select the Tree View element and select the Design command in the context menu.
