Dropdown Custom in Dynamo Player

[joaoluiz.sribeiro]

Hi, Guys"

I want to know if someone uses a custom dropdown list in dynamo player?
I found some custom nodes to create a dropdown list like Data-shapes,Rhythm, DropdownUI (that didn’t work in dynamo player).

Thanks \o/

Hi @joaoluiz.sribeiro

You can only make a custom dropdown list in dynamo player if you can program C#.
Here is the tutorial and sample files for making custom UI:

If you do not want to rely on 3rd party nodes, this could be a solution for you.

No - I believe it is 2024 product line. C3D may not have consumed the Dynamo version though.

This is a great feature, but I don’t think it can take a list as input.

Is there a way to do that? I tried using Windows.Form but there is this bug in R24

Error when using Windows Form Events with Python in Dynamo for Revit 2024

Hi, I have created a couple of scripts where I use a Python node to display a Windows Form for a better user experience. This has worked fine for Revit 2023 and earlier. However, when trying to run these scripts in Revit 2024, I get an error message saying: “System.Reflection.Emit.TypeBuilder not found.” See the attached picture. Through a lot of testing, I found out that it is different events like .Click etc., that cause the error. I have made a simple example with a form and a clickable …

It only takes prewritten values. If you want a dynamic dropdown, the Data-Shapes package works best.

Thanks Gavin, this there a way to do this in Dynamo Python? I won’t want the user to have to install 3rd part package because that will open another can of worms, my windows form worked in R23 but not R24

Hi,
may be a solution requiring work, you use your custom list which you branch at the end of this node with valueatkey on a dictionary composed of your personalized list

I believe winforms have issues in CPython3, so might need to wait on PythonNet or install IronPython2.7 at least. See below post:

GUI ComboBox in CPython3

for now, there is an issue with PythonNet2, you can use IronPython(2 or 3) or C# instead we will probably have to wait for the integration of PythonNet 3 into the CPython3 engine to resolve the problem strange, if you click on the button it’s works ?
