I want to select and unselect rows of a dataframe i load.
here is the code
but i am unable to use “Unselect cards” and “Select Cards” if i already clicked on the select box in the app. “unselect cards” works only after i clicked “Select Cards” and all cards are selected. Then I am able to unselect some by hand and all via “Unselect Cards”.

Share the Streamlit and Python versions.
Streamlit, version 1.34.0
Python 3.9.19

I tried to include both

st.session_state.df_with_selections[“Select”] = False
st.session_state.edited_df[“Select”] = False
in the buttons

but only st.session_state.df_with_selections[“Select”] = False
is needed. I can only select unselect in one direction.

Update the session state data with any changes made in the data editor

st.session_state.selected_rows.update(st.session_state.df_with_selections)

st.write(“Your selection:”)
st.write(st.session_state.selected_rows)`
