How to create enum drop box in Sequence call parameter list

[luklem]

Hello,

Is it possible to change how my SequenceCall step passes arguments? Right now, the Step.Module.ActualArgs variables are containers, that contain Expression as the actual type. I would like to add a select box that my end user could conveniently click and select instead of writing all vars as expressions.

Hi luklem,

As I see this feature is not available in the UI. You can create enums as custom data types and add the sequence parameter based on this enum data type, but the drop down selection is not implemented.

Or you can create your additional custom step type edit tab in the Step properties pane, but it needs additional programming in .NET, and there you can implement your customer's needs:

Thanks for clarifying. I thought that by chance there would be an option to pass something else, rather than Expression
