Changing value of Property, when another property changes

[Shai Samuel]

I am using IndicatorBaseConverter to toggle some input properties visibility On/Off from the Indicator UI.

I would like to change the existing value of a property, base on value of another property.

For example, if I have a property such as fastPeriod, I would like to set the value 1 to it, if UsePeriod is set false using the UI.

Hello Shai Samuel,

Thanks for your post.

Please see this reference sample from the NinjaTrader 8 help guide which demonstrates using a TypeConverter to customize property grid behavior:

https://ninjatrader.com/support/helpGuides/nt8/using_a_typeconverter_to_custo.htm

There are 5 different use cases demonstrated in the reference sample linked above.

1. Dynamically manipulate what is displayed on the UI Property Grid

a. Show / hide properties based on secondary input

b. Disable / enable properties based on secondary input

2. Customizing how a property is displayed

a. Display "Friendly" enum values

b. Re-implement a "bool" CheckBox as "Friendly" a ComboBox

c. Display a custom collection / list with user defined values at run time

Let me know if I may further assist.

NinjaTrader_BrandonH An observation on details in your post. The link (and its display) are incorrect, and have a space introduced in the text. Absolutely no doubt you entered everything correctly! This is a flaw in the Forum software that has been obvious for a long time. It sometimes introduces a space in the middle of text. When it happens, one can edit and repost, and that sometimes fixes it, but other times, the flaw persists. This should be fixed by the Forum software provider.

Thanks.

Hello jeronymite and Shai Samuel,

Thanks for your notes.

I have reposted the link in post # 2 so that it leads to the correct reference sample and reported this behavior.

Please let me know if I may assist further.
