Enable/Disable is NOT working for Lot Serial Nbr. Selector field on Details Grid.

Hello All,

I have been working on trying to disable the Lot/Serial Nbr. selector field on the grid section of the Inventory Receipts screen (IN301000) through code, but it’s not working as expected.

I was able to successfully disable the unitCost field on the same grid, so I’m not sure what is preventing the Lot/Serial Nbr. selector field itself from being disabled/enabled.

 

Here is the code I am using:
 

public class INReceiptEntry_Ext : PXGraphExtension<INReceiptEntry>
{
    protected void _(Events.RowSelected<INTran> e, PXRowSelected baseHandler)
    {
        baseHandler?.Invoke(e.Cache, e.Args);
        if (e.Row == null) return;
        PXUIFieldAttribute.SetEnabled<INTran.lotSerialNbr>(e.Cache, e.Row, false);
    }

}

 

If anyone could help me with this, it would be really helpful.

Hey ​@dhruv40, The SetReadOnly usually works when SetEnabled doesn't because something else might be re-enabling the field after your code runs.
so try this snippet with your conditions (it works for me):
 

 protected void _(Events.RowSelected<INTran> e, PXRowSelected baseHandler)
 {
     baseHandler?.Invoke(e.Cache, e.Args);
     if (e.Row == null) return;
     PXUIFieldAttribute.SetReadOnly<INTran.lotSerialNbr>(e.Cache, e.Row, true);
 }


I hope it helps!

Hello ​@dhruv40, You can try with customization editor:

In Field section (under IN301000 screen) just add DAC & set ‘Disabled = True’

Add Field & set Disabled = True

I hope it helps!

The INTran.LotSerialNbr field uses the [INTranLotSerialNbr] attribute to configure the selector among other things.

INTranLotSerialNbrAttribute inherits INLotSerialNbrAttribute which contains this code:

public virtual void FieldSelecting(PXCache sender, PXFieldSelectingEventArgs e)
{
    ILSMaster iLSMaster = (ILSMaster)e.Row;
    if (iLSMaster != null)
    {
        PXResult<InventoryItem, INLotSerClass> pXResult = ReadInventoryItem(sender, iLSMaster.InventoryID);
        ((PXUIFieldAttribute)_Attributes[_UIAttrIndex]).Enabled = !ForceDisable && pXResult != null && sender.AllowUpdate && IsTracked(iLSMaster, pXResult, iLSMaster.TranType, iLSMaster.InvtMult);
    }
}

You’ll notice it’s setting the ‘Enabled’ property depending upon some conditions.

There are a couple ways you could approach this. I would start by writing a FieldSelecting statement (override) for LotSerialNbr and see if setting the value there fixes it.

​@Abhishek Niikam 

tried that solution, but the thing is it completely disables the field, whereas I want it to be disabled only under a certain condition defined in my code.

Although, thank you for the help and response.

Hello ​@darylbowman, I tried using both RowSelecting as well as  FieldSelecting but did not seem to resolve the issue.

I am not able to find any ways to make LotSerialNbr  field Enable/Disable via code.

I’m not sure if there’s an easier way or not, but I’m pretty sure creating a new attribute that inherits the original attribute class and overrides the FieldSelecting event to include your logic would solve the issue.

Thank you ​@Abhishek Niikam, I tried using SetReadOnly instead of SetEnabled and it worked how I wanted it to perform on lotSerialNbr field.

 

Thank you ​@darylbowman, for suggestion and help.
