You can find the checked members of a dimension from the underlying MetaTreeNode of MemberEditor window. By iterating child nodes in MetaTreeNodeCollection, you can find the selected/checked state of each member of a dimension.
In the following code example, consider the column axis of AxisElementBuilder as an example. Here the Measures are excluded, as only the selected/checked members from a dimension are retrieved.
On iterating the members besides a dimension, the IsSelected property of the node is checked. If it’s true, the member is selected and added to the collection else not.
