Hi, can I ask for help? Is it possible to control xpression dropdown lists in the data source tab (list box, combobox, radio buttons, checkboxes) of xpression using dashboard?

Thanks in advance for your suggestions.

Yes, if you setup a dashboard datalinq connection but don’t select XML layout you can use dashboard parameters.

Thank you very much for your answer.

Can I ask for more details, what parameter should I use in the dashboard? I am attaching a simple project example and excel file.

Thanks in advance.
