Introduction:

Recently I got a situation where I need to lock the fields in editable grid. I tried to find the solution on internet. I found a suggestion as to use business rule having scope to “Entity”. But it did not worked as it was locking the fields on forms also. Then I created another business rule having scope to “All Forms” to unlock fields. But it was unlocking the fields on grid also. So, decided to add a script on view load, but there is no event for that. There are only onSave and onRecordSelect handlers for views. Then I learned that whenever we try to edit a field the records automatically get selected. So, I can achieve desired result by adding script on onRecordSelect event handler.

In this blog I am going to explain how to lock fields on editable grid.

Step-by-Step:

1. Create a new script web resource and add below code

2. function fnLockFields(executionContext) {
         let oFormContext = executionContext.getFormContext();
         if (oFormContext) {
             let arrFields = ["subject", "regardingobjectid", "ownerid"];
             let objEntity = oFormContext.data.entity;
             objEntity.attributes.forEach(function (attribute, i) {
                    if (arrFields.indexOf(attribute.getName()) > -1) {
                       let attributeToDisable = attribute.controls.get(0);
                       attributeToDisable.setDisabled(true);
                    }
             }
   });
   }
   

2. Now, go to Settings -> Customization -> Customize the System -> Entities(select your entity) -> Events -> Add Web resource library->Add OnRecordSelect event handler and add function name.
3. 
3. Pass the execution context as first parameter.
4. Save and publish.
5. Now, when you try to edit any locked attribute, selected attributes will be locked.
