Hi Juan,

If I understood your question correctly, it can be done if the child element is known.
The documented approach is to use the DataMinerSystem library to retrieve that element and then retrieve the parameter from it.

For a standalone parameter in a QAction, this can be done, for example, as follows:

IDms dms = protocol.GetDms();
IDmsElement childElement = dms.GetElement(new DmsElementId(346, 530006));
IDmsStandaloneParameter<string> parameter = childElement.GetStandaloneParameter<string>(10);
string value = parameter.GetValue();

For table data, retrieve the table through GetTable(...) and then use GetRow(...) or GetData(...), depending on whether a single row or multiple rows are needed.

Hi Vasco

I thought about using direct querying to each element, but it requires having the service parameters in the code. Is there any way to query the service for the elements that are already filtered?

Thanks

Hi Juan, you can try retrieving the service with IDms (IDms.GetService).
From the service returned access, you can get the list of included parameters as shown below.

IDmsService.ParameterSettings.IncludedParameters, which contains the ID of the element, but also ServiceParamSettings.ParameterFilters that contain the ID of the parameter.

Please find below a quick example:
public class Script
{
   public void Run(IEngine engine)
   {
       var dms = engine.GetDms();

       // Retrieve the service by its ID
       int serviceId = 1234; // Replace with your actual service ID
       var service = dms.GetService(serviceId);

       // Access the included parameters of the service
       var includedParameters = service.ParameterSettings.IncludedParameters;

       // Iterate through the included parameters to find parameter filters
       foreach (var paramSetting in includedParameters)
       {
           var parameterFilters = paramSetting.ParameterFilters;

           // Check if there are any parameter filters
           if (parameterFilters != null && parameterFilters.Any())
           {
               // Retrieve the first parameter ID from the filters
               var firstParameterId = parameterFilters.First().ParameterId;
              
               // Output the parameter ID
               engine.GenerateInformation($"First Parameter ID from Filter: {firstParameterId}");
               break; // Exit after finding the first parameter ID
           }
       }
   }
}
