NinjaTrader_ChelseaB Hello.

This modified script prints the following:

EnumValue: MyCustom2
ReadOnlyString: MyCustom2
EnumValue: MyCustom2
ReadOnlyString: MyCustom2
EnumValue: MyCustom2
ReadOnlyString: MyCustom2
strategyInstance.ReadOnlyString: MyCustom2
strategyInstance.EnumValue.ToString(): MyCustom3
strategyInstance.EnumValue: MyCustom3
strategyInstance.ReadOnlyString1: MyCustom2
value: MyCustom3
strategyInstance.ReadOnlyString: MyCustom3
strategyInstance.EnumValue.ToString(): MyCustom2
strategyInstance.EnumValue: MyCustom2
strategyInstance.ReadOnlyString1: MyCustom3
value: MyCustom3
strategyInstance.ReadOnlyString: MyCustom3
strategyInstance.EnumValue.ToString(): MyCustom1
strategyInstance.EnumValue: MyCustom1
strategyInstance.ReadOnlyString1: MyCustom3
value: MyCustom2

Why doesn't the strategyInstance.ReadOnlyString value updates to the strategyInstance.EnumValue.ToString() value when changing the strategyInstance.EnumValue.ToString() selected value?

The prints look right but no difference in the windows strategyInstance.ReadOnlyString field when changing the strategyInstance.EnumValue.ToString() selected value :

I takes clicking the strategyInstance.ReadOnlyString Window field then the strategyInstance.EnumValue.ToString() one for it to print.

Ticking the bool checkboxes do update the strategyInstance.ReadOnlyString as desired. But not when changing the strategyInstance.EnumValue.ToString() selected value. That is the end use needed.

Will you take a look and test on your side with the attached script to pinpoint accurately what the issue is and potential fix?

Hello PaulMohn,

I'm uncertain about this, but may have to do with converting the enums to strings.

Have you tried not doing this and using a switch to set a specific string instead of trying to convert the enums to strings and back?

NinjaTrader_ChelseaB Hello,

Turns out this is working:

https://pastecode.io/s/h7zizdnp

By creating some new class scope string variables
private string enumtoLabel0,enumtoLabel1;

Then using an exact copy of the MymainEnum enum inside the protected void CreateWPFControls() scope,
then LINQ for matching the enums' Main values to the Properties UI Chart Windows actual selected values:

        protected void CreateWPFControls()
        {​
         ...
                        #region ENUM VALUEs TO SET THE BUTTONS LABELS VALUES
                            
                            MymainEnum[] MymainEnumFilterArray = new MymainEnum[]
                            {
                                MymainEnum.Item1,
                                MymainEnum.Item2,
                                MymainEnum.Item3,
                                MymainEnum.ItemA,
                                MymainEnum.ItemB,
                                MymainEnum.ItemC,
                            };
                            
                            if ( MymainEnumFilterArray.Any(s => s.Equals(EnumValA)) )
                            {
                                enumtoLabel0 = EnumValA.ToString();
                            }
                            
                            if ( MymainEnumFilterArray.Any(s => s.Equals(EnumValB)) )
                            {
                                enumtoLabel1 = EnumValB.ToString();
                            }

                        #endregion​

It does not need the button property to set the Button label — no need to
use the (State == State.SetDefaults) scope strings.
Nor using the TypeConverter extra classes / methods.

region BUTTONS PARAMETERS

//Button0Label = "Btn0Lbl";
Button0Color = Brushes.ForestGreen;
_button0Ticks = 4;


//[NinjaScriptProperty]
//[Display(Name="Label Button 0 On", Order=1, GroupName="Button #0 Parameters")]
//public string Button0Label
//{ get; set; }

It works as expected and is good enough for now.
Still curious and will test to see how to do that from the Properties / (State == State.SetDefaults) scope strings approach.

Or simple assignment via extra string is working too:

https://pastecode.io/s/iko2375n

namespace NinjaTrader.NinjaScript.Strategies
{
   ...

    public class _EnumtoLabel : Strategy
    {
        #region #4 CLASS VARIABLES - CreateWPFControls() - BUTTONS : ENUM TO BUTTONS LABELS STRING VARIABLES
            
            private string enumtoLabel0,enumtoLabel1;

        #endregion        
        
        
        ...
        
        protected void CreateWPFControls()
        {
                #region BUTTONS
                    
                    #region BUTTONS ARRAY AND LOOP
                    
                        #region ENUM VALUEs TO SET THE BUTTONS LABELS VALUES
                    
                            enumtoLabel0 = EnumValA.ToString();
                            enumtoLabel1 = EnumValB.ToString();
                    
                        #endregion
                        
                        #region BUTTONS CREATING LOOP
                            
                            buttonsArray = new System.Windows.Controls.Button[2];

                            for (int i = 0; i < 2; ++i)
                            {
                                System.Windows.Media.Brush ButtonBackground;
                                string ButtonLabels, ButtonTicks;
                        
                                switch(i)
                                {
                                  case 0:
                                    ButtonLabels        = enumtoLabel0;
                                    ButtonBackground    = Button0Color;
                                    ButtonTicks         = subTicksCheck0;
                                    break;
                                  case 1:
                                    ButtonLabels        = enumtoLabel1;
                                    ButtonBackground    = Button1Color;
                                    ButtonTicks         = subTicksCheck1;
                                    break;
                                    
        ...​

Or no assignment via extra string but assignment
to the Properties UI Chart Windows actual selected values straight to the
CreateWPFControls() loop/switch variables is working too:

https://pastecode.io/s/xsm4eq22

namespace NinjaTrader.NinjaScript.Strategies
{
   ...

    public class _EnumtoLabel : Strategy
    {
        ...
        
        protected void CreateWPFControls()
        {
                #region BUTTONS
                    
                    #region BUTTONS ARRAY AND LOOP
                        
                        #region BUTTONS CREATING LOOP
                            
                            buttonsArray = new System.Windows.Controls.Button[2];

                            for (int i = 0; i < 2; ++i)
                            {
                                System.Windows.Media.Brush ButtonBackground;
                                string ButtonLabels, ButtonTicks;
                        
                                switch(i)
                                {
                                  case 0:
                                    ButtonLabels        = EnumValA.ToString();
                                    ButtonBackground    = Button0Color;
                                    ButtonTicks         = subTicksCheck0;
                                    break;
                                  case 1:
                                    ButtonLabels        = EnumValB.ToString();
                                    ButtonBackground    = Button1Color;
                                    ButtonTicks         = subTicksCheck1;
                                    break;
                                    
        ...​

The point being it does work because the CreateWPFControls() method is called/updates
every time the Chart Properties Windows is reloaded/it's "Apply" Button is clicked.
The buttons being recreated every time.
No need for the TypeConverter approach then.
