Cannot change the grid column width after modifying the DAC field

Hi,

I’m customizing a new screen, In my screen I have a grid with some fields taken from my customized DAC. I modified some fields with Enabled=false property because I don’t need to allow edit those fields from the UI. below example for the reference.

#region Ponbr
        [PXDBString(15, IsUnicode = true, InputMask = "")]
        [PXUIField(DisplayName = "Sales Order Number", Enabled = false)]
        
        public virtual string Ponbr { get; set; }
        public abstract class ponbr : PX.Data.BQL.BqlString.Field<ponbr> { }
        #endregion

        #region POLineNbr
        [PXDBInt()]
    [PXUIField(DisplayName = "Sales Order Line Number", Enabled = false)]
    public virtual int? POLineNbr { get; set; }
    public abstract class pOLineNbr : PX.Data.BQL.BqlInt.Field<pOLineNbr> { }

    #endregion

But after adding them, I’m unable to change the width of these columns in the grid as required. Before modifying them , I had changed the width property in layout properties of these fields as needed. But now it is not working. However when I applied a size to the width and previewed, I can see the changes are applied, but after publishing , changes are not applied to the grid of the screen.

I have no idea on this, Can someone suggest me a solution to fix this?

Thank you.
