How to create dropdown component in GH C#?

How to create a dropdown in C#? I have a list on enums: public enum PanelType { Undefined, Wall, WallExternal, WallInternal, } and trying to make a component that will allow user to select via the drop down… here is my GH script for the component below. Any help will be really appreciated namespace SAM.Analytical.Grasshopper { public class AnalyticalPanelType : GH_Component { /// <summary> /// P…

kind regards - tom

thanks for solotion but i test this method and don’t get results!

            param.AddNamedValue("None", 0);
    param.AddNamedValue("Sharp", 1);

thanks @Mahdiyar @DavidRutten
if my valuList input is string how?

c#
public class Lineweight : GH_Component
{
public Lineweight()
: base("Lineweight", "Lineweight",
"Lineweight",
"Intersect", "Actions")
{
}
protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager)
{
    pManager.AddCurveParameter("Curve", "C", "Curve", GH_ParamAccess.item);
    pManager.AddIntegerParameter("Width", "w", "Width", GH_ParamAccess.item);
    pManager.AddColourParameter("Colour", "C", "Colour", GH_ParamAccess.item);
    pManager.AddTextParameter("Dash", "D", "Dash", GH_ParamAccess.item);
    var Dash = (Param_String)pManager[3];
  Dash.AddNamedValue("dastdot", "1.0 1.0 0.1 1.0");

For Param_string [AddNameValue]errors found!

As far as I know, AddNamedValue only works on Integer parameters.

thanks
hi
@dale
What do you have for the right solution for this problem?

[dale (Dale Fugier)]

Hi @architect.civil5,

@Mahdiyar is correct, Param_Integer.AddNamedValue only accepts integer values.

Think of the second parameter as an index into a list of options or values, rather than just some value.

I’ve attached an example for you to review.
