I am having trouble extracting the data-type from an AgGrid column dynamically. in my case, the AgGrid starts with no data (i.e: rowData = []), meaning I can’t just iterate over rowData and extract the type of the value stored at any field, and I populate the data with a callback to rowTransaction f…

ok, took your suggestions. Now store_props = { "children": [ '{"row_format":{"field1":"str", "field2":0.0}, "selector_field":"field1"}' ] } and in the callback I do: row_info = json.loads(store) field = row_info["selector_field"] try: field_dtype = getattr(__builtins__,row…

Hi @jinnyzor , thank you for the reply. Is there a way in my AIO to pass additional properties that can be used in callbacks? for example, AIO components are structured such that I need to pass sucomponent props to the class constructor. Can I define custom props for the AIO component itself, or is …

Correct, AIO components can only have props from the underlying components. If done correctly, you shouldnt have an error with it. In my personal use, I have functions that return the configured grid that falls into pattern-matching realms, thus I only have a pattern-matching callback to deal with…

[image] jinnyzor: dash_ag_grid.getApi Thank you for the reply! It’s helpful to know. I cannot find getApi in the dash AgGrid reference. Can you please point me to it? Thanks!

Sure, take a look at this example: Row Dragging - External Dropzone | Dash for Python Documentation | Plotly Drag and drop rows in an external dropzone - Including grid to grid

Thanks! Also, I am guessing global variables inside the callback are a no-no? for example within the callback declare global row_format and then outside of the AIO define row_format = {"field1":str, "field2":int} ?

Global variables are useful if you are the only user using the application and you will only have one session in use. If you plan to not do the above, then you should avoid them and only declare things within the scope of the callback. Return any variables to be picked up by the app with functions. …

Ok! That’s what I thought. Do you know why I get Error loading layout when I try to use a dcc.Store in my AIO component? I don’t think I have the technical background to understand why. I am getting the following error: File python3.11/json/encoder.py", line 180, in default raise TypeError(f'O…

Without seeing how you are spinning it up, I’m not sure. Something seems to be crashing it.
