Hi everyone, I found a few examples in this forum on how to make the whole DataTable row highlighted when a cell is selected. But I am struggling to integrate that with an already-existing callback. Here’s my code that works (no row selection function): xenosaga/app.py at master · perfectly-preser…

Hi @the.oldest.house Try putting the style update in it’s own callback: @app.callback( Output("datatable-interactivity", "style_data_conditional"), Input("datatable-interactivity", "active_cell"), ) def render_content(active_cell): style = style_data_conditional.copy() …

Thanks! I was able to get that working in my app, but I had to sacrifice the tab selection callback. I’m having trouble getting both to work at the same time. I think the reason why Dash is saying it can’t find my DataTable’s ID datatable-interactivity is because I’m dynamically rendering the DataT…

If the ID is added via a callback, this is expected behavior. :slight_smile: Demonstrated by this line: If you are assigning callbacks to components that are\ngenerated by other callbacks (and therefore not in the\ninitial layout), you can suppress this exception by setting\n'suppress_callback_exc…

Just to tag on to @jinnyzor correct answer, here is some more info from the dash docs: Callback Gotchas | Dash for Python Documentation | Plotly

Thank you both, that explains it then. I’m all set and I’ve learned something new today. I appreciate the help!
