How best to populate eto GridView control from Python dictionaries?

If I have aggregated data in a list of dictionaries, e.g.

[ 
{"name":"Smith", "rank":"Major", "serial":1234},
{"rank":"Corporal", "name":"Jones","serial":9876}, 
...etc
]

is it possible to load the values directly into the eto GridView DataStore? Or do they first have to be converted to lists as used in the example in the Rhino developer documentation?

Can anybody supply an example of the best way to go about this?

Hi @jeremy5,

Maybe this sample helps?

test_gridview_dialog.py (2.1 KB)

Hi Dale,

Thanks for the example. Unfortunately, if I run it in the R8 editor I get the following exception:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Rhino.Runtime.Code.Languages.PythonNet.CPythonCode.Execute(RunContext context)
   at Rhino.Runtime.Code.Code.ExecTry(RunContext context, IPlatformDocument& doc, Object& docState)
   at Rhino.Runtime.Code.Code.Run(RunContext context)

It runs with RunPythonScript.

Let me have a look…

It runs that way for me too, so I can see the dialog and relate elements of the code to it. Thanks

I just updated to the latest SRC and get a more informative trace from the editor:
