So, the Iframe loads the Dashboard and the user can interact with the dashboard and set different values for Product_id and Channel_id by using the tick-box filters on the dashboard.
The Question is this:
For our purposes we want to know what values the user has reset the filters to. IE we want the web-application to know what the current values for Product_id and Channel_id are. Theoretically, to do this the parent frame for the tableau dashboard Iframe will need to be able to read the current values for Product_id and Channel_id from the Tableau Dashbaord Iframe.
Has anyone done this / tried this successfully? Should it be possible? Any other suggestions?
