Hello,
I have a table with list of compsed rows (labels, dropdown, input text ...)
When i refresh my web page (F5), i lose all the data in the table.
this bhavior is normal since i populate my table with an inject node containg the sql query.
Is there a way to detect that the user refresh the page so i can execute again my sql select query ?
thank you in advance for help

Hi @AliBenBelgacem - if you are talking about Node-RED Dashboard, then the `ui_control` node can be used to detect when the dashboard is opened.
If you aren't talking about Node-RED Dashboard, then you'll have to provide more details.

Am using ui\_template to create the table.
How to include the ui\_control to achieve my goal ?

Find the `ui_control` node in your palette and add it to your workspace. Then read its help text in the info sidebar.
