Help with dynamically created components

Dash Python
1

Thank you @AIMPED . The solution worked.
If possible, do you happen to know how do I get specific DataTable data in callback function (I have multiple tables) ? The challenge I think is the id value is dynamically generated so I cannot specify it in the State in @callback
Thanks Again.

How is the ID generated?

The table is generated after the file upload is done. Like this -

dash_table.DataTable(
                data=df.to_dict('records'),
                id=filename.replace('.','-'),
                columns=[{'name': i, 'id': i} for i in df.columns],
                page_size=5,
                style_table={
                    'width': '80%'
                },
                style_cell={
                    'textAlign': 'center'
                }
            ),

Why do you need dynamic ID’s for your app? Maybe you should take a look at pattern matching callbacks:

Okay Thank you. Let me check. For now I have stored the filenames and data globally and handling it. When I go for login session , I might have to handle it differently.

How can I access specific DataTable data in a callback function when I have multiple tables with dynamically generated id values? The challenge lies in not being able to specify the id in the State for @callback.

I was able to handle it with a global python variable and append the tables to that list variable, and then fetch it in the display area.
