I cant override a Method

I looked at the class source code you mention briefly and noticed something curious.  There is a partial class defined in the class file for RefreshRate that includes a class header comment referencing:

     “RefreshCurrencyRates.RefreshRates(RefreshFilter, List{RefreshRate}, string)”

Notice the third parameter.  Is this an incorrect header comment, or is there a third parameter hidden from us somehow? I don’t know the answer.
 

In any case, two things I would suggest to try are (1) in your PXOverride method, call Base.RefreshRates() instead of the delegate method.  However, I’m not quite sure if that would cause an endless loop if calling the Base would then call the PXOverride method again.  (2) Don’t PXOverride the method, but instead add an event handler for RefreshFilter_RowSelected that calls your new method instead of the base version of RefreshRates().

Thank you very much Tony I will follow your advice.

the first option I hope is well implemented but fail:

        [PXOverride]
        public void RefreshRates(RefreshFilter filter, List<RefreshRate> list)
        {
            // Your custom logic here
            Base.RefreshRates(filter, list); // Call the base method directly
            throw new Exception("");
        }

You're right Naveen, I had also thought about it. I'm going to do it. Thank you very much, everyone, for your time.

Hello @victorcerecero . You may already have found a solution. But just in case, looks like @Tony Lanzer ‘s 2 option works well: Don’t PXOverride the method, but instead add an event handler for RefreshFilter_RowSelected that calls your new method instead of the base version of RefreshRates().

So, for example you can write your custom method and override the RowSelected evet to set your method as the delegate. Here is an example with a custom method with a condition to execute or call the original one:

        protected virtual void _(Events.RowSelected<RefreshFilter> e, PXRowSelected baseMethod)
        {
            RefreshFilter filter = e.Row;
            if (filter != null)
            {
                Base.CurrencyRateList.SetProcessDelegate(list => CustomRefreshRates(filter, list));
            }
        }

        public virtual void CustomRefreshRates(RefreshFilter filter, List<RefreshRate> list)
        {
            if (your_condition == true)
            {
                // Do your custom process here
            }
            else
            {
                // Call original method in some other cases
                this.Base.RefreshRates(filter, list);
            }
        }

Hello @Marco Villasenor, Thank you for your response, Yes, indeed, the issue was resolved through what you mentioned. The event finally allowed adding the required functionality. Thank you very much, Marco. Greetings to our friends at Interastar.
