return df().iloc[list(selected_rows)]
app = App(app_ui, server)Behavior
I have issue geatin reactive event from dataframe editing, so I can not apply changes to the dataframe. Therefore, I have used the example code, but same behaviour:
https://github.com/posit-dev/py-shiny/blob/main/examples/dataframe/app.py
This is never executed, after editing cells
@reactive.effect
@reactive.event(input.grid_cell_edit)
