List Box on chart

[pman777]

Looking for guidance on how to display a list box on a chart (like a button) ... the list will be populated by an enum list. It should function the same as a list box that would appear in the parameters section, but I need it to display in the header section of the chart itself.

I realize this is more of a C# question than NT7, but would be grateful if someone can direct me to a resource which can explain how to do this. thanks

Don't remember where I picked this up.

Hope it helps.

Thank you shuglu! Appreciate your response. One more question. I need to populate the ToolbarDropdown with the ATM strategy names. I already have a section of code that accesses the strategy names to populate a list in the parameters section (see code below in blue), but not sure how do I get these ATM strategy names in the ToolbarDropdown. Any insight will be greatly appreciated! tx

#region StringConverter
public class AtmConverter : StringConverter
{ public override bool GetStandardValuesSupported(ITypeDescriptorContext context) { return true; }
public override bool GetStandardValuesExclusive(ITypeDescriptorContext context) { return false; }
public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
{ string[] sarr = new string[0];
foreach (StrategyData data in NinjaTrader.Db.Globals.Engine.GetObjectSet(typeof( StrategyData), "category = " + 2))
{ if (data.Strategy is AtmStrategy)
{ Array.Resize<string>(ref sarr, sarr.Length+1); sarr[sarr.Length-1] = data.Strategy.Name;
} }
foreach (StrategyData data in NinjaTrader.Db.Globals.Engine.GetObjectSet(typeof( StrategyData), "category = " + 1))
{ if (data.Strategy is AtmStrategy)
{ Array.Resize<string>(ref sarr, sarr.Length+1); sarr[sarr.Length-1] = data.Strategy.Name;
} }
return new StandardValuesCollection( sarr );
}
}
#endregion

Hello pman777,

This would be far outside of the realm of NinjaTrader Support, however, you have a for loop in your converter that is likely populating these values.

foreach (StrategyData data in NinjaTrader.Db.Globals.Engine.GetObjectSet(typeof( StrategyData), "category = " + 2))
