Dynamically changing parameters based on parameter value

[Shai Samuel]

How can I dynamically change the parameter list, when one parameter (typically enum) have specific value?

I am aware of C# 3.5 overloading options, where you can have a different parameters list (and different behaviors) for the same name method. But this addition is like adding a certain rule over the overloading.

If I was not clear, please see the 2 attached images of example of an indicator that does this (by one of your echo-system partners). In the first one, you can see the list of params when Type=Price, and in the other you can see a different list of params when Type=Indicator.

Can you add an example code of how this can be done?

Hello Shai Samuel,

Thank you for writing in. You need to have your indicator implement the ICustomTypeDescriptor interface. Then each dynamic parameter must have the following code:

[RefreshProperties(RefreshProperties.All)]

Please be aware that this is not officially supported but has been used by other customers in the past.

I have attached an example of an indicator that implements the ICustomTypeDescriptor interface which you can use for reference.

Please let me know if I may be of further assistance.
