Hello @Ru,

 

You achieve this by querying the service where this data is coming from (GetImplementingThingsWithData vs QueryImplementingThingWithData for example). Basically, you would need to call the query service every time SelectedRowsChanged event is triggered on the DropDown widget. Then, you can use the SelectedText property of the DropDown widget to query the infotable and only return the results that match the query. Find a summary below:

 

  1. Bind SelectedRowsChanged (DropDown) > QueryService
  2. Bind SelectedText (DropDow) > QueryService (string parameter)
  3. In QueryService, use the SelectedText (string input) to query the database/infotable
  4. QueryService should return an infotable containing only the rows that match the selected level

I hope you find this information helpful.

 

Thanks,

Emmanuel

If I'm doing this , i'll just use a Datatable entity with Shape { String:[Level], infotable:[Courses] }

 

So I just need 3 rows of data for your 3 levels, and in each infotable after the certain level, I'll list all the submashup names.   I'll bind the GetdatatableEntries service result to both List widget and Collection widget, showing different columns of data.  With the help of SelectedRows change event, list and collection widget will change at same time.
