I’m trying to setup a combo box for Prodgroup group. In preview mode it lists the product codes in our system but the returned grid isn’t filtered properly. I added a text box and set it to the same search filter and it displays the correct ProdCode so in-theory should work but doesn’t. In the where list I tried matches and = but none work.
I followed the instructions from Hannah and this thread
Preview Results;
Combobox Settings:
Filter:
If you don’t have multiple Where Clauses… you can do it outside in BAQ Options:
This one works for me:
Interesting, won’t work in this case as we have a total of eight filters. 
Could work on another dash I’m uplifting though.
Another thing you can try is to filter the grid by an event using dataview-filter-set.
So your BAQ would run wide open and fully populate the DataView. Then use the event to filter the dataset after the fact.
I used the one above on a SalesRep Combobox tied to TransView.SalesRepFilter
The condition is just to make sure I have a value: '{TransView.SalesRepFilter}' === ''
If FALSE… then I filter the target dataview (“Orders” in my case):
The Filter here can include multiples:
Orders.Calculated_SalesRep1 = '{TransView.SalesRepFilter}' OR Orders.Calculated_SalesRep2 = '{TransView.SalesRepFilter}' OR Orders.Calculated_SalesRep3 = '{TransView.SalesRepFilter}'
The problem I was never able to solve was “clearing” the filter. That was my TRUE side of the condition. I was hoping clearing the combobox would give me a value of ’ ’ … and then the filtered grid would revert back to the full dataview results… but I couldn’t get that to work.
So, the false branch works, but clearing the filter is still a mystery to me.
I deleted everything in the Where List and recreated them one at a time then tested the dashboard. Now the filters are working as intended in DevTools. Guess I ran into a bug?
Now to fight the column layout and hidden 
err 
Thanks I’m keeping this suggestion in my notes!
Go figure! At least its working!
