title: How to display DropDown options using values from two fields
body: <p>I have a DropDown that shows a list of indicators. I want it to display as options values from two fields <em>IndicatorCode</em> and <em>IndicatorName</em>, ideally it should also have a ": " or any other character in between. As bindings for the DropDown I have:</p>
  
  <p><em>Options</em>: <strong>@datasource.items</strong>, </p>
  
  <p><em>Value</em>: <strong>@datasource.item</strong> </p>
  
  <p><em>Names</em>: I tried the following but it does not work well <strong>@datasources.MyDatasource.items..IndicatorCode+':'+@datasources.MyDatasource.items..IndicatorName</strong></p>
