Show filtered value in a Dropdown Box?

Hello,

I try to get filtered values in Dropdown Box, exist a way to do this?

Example:

DS_1.setFilter("Country", ["DE", "US"]);

DR_COUNTRY.setItems(DS_1.getMemberList("Country",
MemberPresentation.INTERNAL_KEY, MemberDisplay.KEY_TEXT, 10));

I am able to create cascading filters and also I see the filtered value in crosstabs, but
I have to filter the value of my DropDown Box.

Is it possible that the getMemberList method also work with my Filter?

Or is there a way to create my one “ValueTextList” and display the result in my DropDown Box?

like DR_COUNTRY.setItems(MyOneFilteredValueTextList);

In real my filter are more complex and depend on buttons and user input.

I use DesignStudio 1.2

Thanks a lot
Johannes
