Windows Form in Dynamo and IronPython 2.7

[AM3D.BIM.STUDIO]

Good morning.
I am trying and trying to understand a little about “Forms”.
I have developed the following code in dynamo “PYHTON SCRIPT” of revit 2020 that handles IRON PYTHON 2.7 and so far everything was going well until I am trying to implement in the code the “BOMCOLIST” in each of the cells of the “Covering” column where I can show the default value of the “covering other faces” and when clicking on said cell it shows me the other covering configurations that exist in the document, in this way I can select and change the type of covering through my DATA GRID VIEW.
I share the code that is in dynamo.
Thank you very much for your time.

Hi,
you need to implement an DataGridViewComboBoxColumn, I recently shared an example of this here

Cyril-Pop/IronPython-Samples/blob/master/WinForms/DataGridView + DataGridViewComboBoxColumn.py

[AM3D.BIM.STUDIO]

I have the following problem:
What happens is that the Data Grid View only shows me 26 elements when I have 400 elements in IN[0]. What is the reason for this?

Data Grid View only shows me 26 elements when I have 400 elements in IN[0]. What is the reason for this?

because in this example, I use Elements Type instead of instances

see this lines

Thanks for pointing out the problem, thank you,
Now it happens that I have my form as I wish and the ONLY thing I WANT is to be able to move the Overlay column after Category and when I try to do so it closes or an index error appears… could you please help me with being able to move my column to the position I want? I wish

Add the DataGridViewComboBoxColumn after the DataGridView generation

Cyril-Pop/IronPython-Samples/blob/dac103c5aa368cbdaa2de12d0a1c4d39d0f4f553/WinForms/DataGridView + DataGridViewComboBoxColumn.py#L155-L156

[AM3D.BIM.STUDIO]

Following the recommendation, I have placed the line of code but it has returned an error and at the same time you can see that the “Coating” columna has not moved.

[c.poupin]

did you remove this one?

The DataGridViewComboBoxColumn (self._ComboBoxValue) can only be added once (in SetCellComboBoxItems method)

as an alternative, you can also try WPF + MVVM

[AM3D.BIM.STUDIO]

Good day
Could you recommend how I can learn from scratch to work with WindowsForm and IronPython so I can see what things I can do or what you would recommend. I am very interested in creating this type of windows and even much more personalized and advanced ones.

here’s an example of a course, but it’s quite old
