Unique Values

[Bruce]

Is there a way to show only unique values from the data source in this list or is there a way to filter the data source so only unique values are returned?

Hello Bruce,

 
In order to achieve your goal you will need to group data by the field which you need to be unique and then bind the dropdownlist widget.

Check this jsFiddle example.

All the best,
