How do I set the AtmStrategySelector to 'None'?

[wjadevries]

Within a Dispatcher.InvokeAsync I'm using this to update the value of the 'ATM strategy' dropdown:

NinjaTrader.Gui.NinjaScript.AtmStrategy.AtmStrateg ySelector atm = w.FindFirst("ChartTraderControlATMStrategySelector ") as NinjaTrader.Gui.NinjaScript.AtmStrategy.AtmStrateg ySelector;
if (atm!=null) {
   for(int i=0; i<atm.Items.Count; i++) {
      NinjaTrader.NinjaScript.AtmStrategy strat = (NinjaTrader.NinjaScript.AtmStrategy)(atm.Items[i]);
      Print("strat: " + (strat!=null ? (strat.DisplayName + ", " + strat.Name): "null"));
      if (strat!=null && strat.DisplayName==myNewOrderStrategy) {
         atm.SelectedIndex = i;
         break;
      }
   }
}

Works like a charm, but I can't set the ATM strategy to 'None'.
And the Print statement also doesn't list any other value except the values in the dropdown.
So how do I set the dropdown programmatically to 'None'?

Hello wjadevries,

You could use atm.SelectedValue = "None"; to have the None in the list selected.

I look forward to being of further assistance.
