Hello,

I’m unable to understand your question completely.

Please share related code and screencast / screenshot showing the issue.

Sorry Abu.
I attach my code and an image so you can understand.
When I add a record in my form, after clicking the save button, it shows a confirmation message (Accept/Cancel). Line 299 of my code.
This message should only be displayed if, when saving my record, I have selected from the dropdown field of the form a specific item that in my llx_activia_vademecum table is marked with the value 1 in the multodroga field.
If that condition is met, the message should be displayed, otherwise it should not be displayed.
I hope I was clear.
I look forward to your comments.
Thank you

You can refer this demo code which uses callback function for beforesubmit event.

https://www.gridphp.com/demo/demos/editing/js-validation-form.phps

Line 35: callback function which contains all the posted data as function param
Line 136-152: implementation of callback function.

Here you can get the idea from the code and replace it with yours by putting the confirm() function call based of the field condition and return true based on confirm() result.

Thanks Abu.

I am going to review this code and implement it.
Thank you very much as always.
Adrian
