Make field readonly using UI Action

[DevYadav]

Hi Community,
I’m trying to add a button on the Incident table form that, when clicked, should make the State and Short Description fields read-only. Could anyone guide me on how to achieve this?

Thanks in advance!

Hi @DevYadav ,

Why? Please share the business reason as it doesn't make any sense.

Hello @DevYadav 

You can meet this requirement by following the below steps:

• Create a UI Action on the Incident table with the following setup:

  • Action Type: Form Button

  • Client: True

• Script:

function makeFieldsReadOnly() {
    g_form.setReadOnly('state', true);
    g_form.setReadOnly('short_description', true);
}

Result:

Once the button is clicked, the State and Short Description fields will become read-only on the form.

Hope this helps!

Step 1: Create the UI Action (Button)

1. Navigate to System Definition > UI Actions
2. Click New and configure:
   • Name: Lock Fields (or your preferred name)
   • Table: Incident [incident]
   • Action name: lock_fields
   • Form button: true
   • Show insert: false (if you only want it on existing records)
   • Onclick: lockIncidentFields();

Step 2: Create the Client Script Function

Add this script to the UI Action or create a separate client script:

function lockIncidentFields() {
    // Make State field read-only
    g_form.setReadOnly('state', true);
    
    // Make Short Description field read-only  
    g_form.setReadOnly('short_description', true);
    
    // Optional: Show confirmation message
    g_form.addInfoMessage('State and Short Description fields are now read-only');
    
    // Optional: Hide the button after clicking to prevent multiple clicks
    g_form.setDisplay('lock_fields', false);
}

@DevYadav  add below client script in UI Action 

function lockFields() {
  g_form.setReadOnly('state', true);
  g_form.setReadOnly('short_description', true);
}
