How to make PXAction and PXUIFieldAttribute.SetEnabled Work

I do not know why my code is not working or something might be missing.

I am trying to do is use PXAction to disable as specific field, when I compile and run this it my browser would just load into infinity.

Thank you guys!

Here is my code

DAC:

 #region RadnomTest
 [PXDBString(20, IsUnicode = true)]
 [PXUIField(DisplayName = "Random Test")]
 public virtual string RadnomTest { get; set; }
 public abstract class radnomTest : BqlString.Field<radnomTest> { }
 #endregion

GRAPH

#region Toggle Readonly
 public PXAction<ClientProfileNames> ReadonlyToggle;
[PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "Toggle Read-only")]
protected virtual void readonlyToggle(Events.RowSelected<ClientProfileNames> e)
{
    var row = e.Row;
    PXUIFieldAttribute.SetEnabled<ClientProfileNames.radnomTest>(e.Cache, row, true);

 Actions.PressSave();
}
#endregion

Solution

Field state should be set from the RowSelected event, and not as the result of an action such a button click.

If you need to set the enabled status based on the value of another field, I would recommend checking the PXUIEnabled attribute which will let you handle this in a declarative fashion: https://asiablog.acumatica.com/2016/11/pxuienabled-and-pxuirequired-attributes.html
