TestStand API C# creating a UI tab for your custom step

In developing a custom step in C#, the step instance will have a set of values, or properties. These are not values that are injected as parameters for the constructor of the C# object, so the parameters on the .NET Adaptor Module tab are not what we want to populate. We want a different set of properties/parameters that the step's C# method will have access to. So how do you create a new tab at the same level as the step's Properties and Module tab, and design a table of properties (name/value) that appear in that panel?

The widget for entering a value may be a different type for each property in the table, although it is known based on the step type. Please correct me if I am wrong, but it does not look like you can create your own custom Adaptor. We did see how you can create an "Edit" substep, which create a Tab with the name of the step type, but the tab only holds a button, which can then launch a dialog. Functionally similar, but not as tight and clean an integration. If there were a way of adding a custom panel within the Properties tab, at the same level as "General", "Run Options", "Looping", "Post Actions", "Switching", etc., that would be the next best option. Thank you.

One of my test engineers showed me an NI step type called, "StringValue Test". It had a property, "NI_Data" that has an array of properties called "Edit Panels". These existed in the NIStepTypeControls.dll, in a class, NationalInstruments.TestStand.StepTypeControls.StringValueTestLimitsTabInfo of type String. Is it possible to create your own EditPanel and add it to your custom type?

I'm pretty certain creating custom UI's for custom step types is not supported out-of-the-box functionality. After searching through our website, there have been a couple of idea exchange posts about this dating back to 2010. A couple relevant posts are linked below.

Hi Daniel,

 

From the URLs, it appears a number of people have asked for this functionality for the same reason, having a dialog with a button that pulls up a panel is clunky. Plus with the functionality described in http://download.ni.com/evaluation/teststand/Creating_Custom_Step_Type_Edit_Tabs_in_the_Sequence_Edit... , it appears that the only step missing is to be able to add the new StepTypeEditPanelTabInfo class to the NI_Data/EditPanels array. Most of the other properties of a StepType are exposed. How do I programmatically add my StepTypeEditPanelTabInfo to my StepType? Thank you.

Hi Fred,

 

Just do it at first excactly as it is descriped in that document. I recomon to start in next step with small application going to your needs (not more than 2 Controls!!) to figure out how this works. If you understand that stuff you will be able to create extremly effective StepTypes.

 

You can do it
