I need to conditionally set a field to be required

I'm customizing the Sales Order screen as follows:

I'm using the SOOrder_RowSelected event as follows:

    protected virtual void SOOrder_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
    {
        var soorder = (SOOrder)e.Row;
        if (soorder == null) return;

        string ordtype = soorder.OrderType;
        var soot = (SOOrderType)PXSelect<SOOrderType,
                                Where<SOOrderType.orderType, Equal<Required<SOOrderType.orderType>>>>.Select(Base, ordtype);

        if (soot != null)
        {
            var sootext = PXCache<SOOrderType>.GetExtension<SOOrderTypeExt>(soot);

            if (sootext != null)
            {
                PXUIFieldAttribute.SetRequired<SOOrder.customerOrderNbr>(sender, sootext.UsrRequireCustOrdNbr == null ? false : (bool)sootext.UsrRequireCustOrdNbr);
            }
        }
    }

This DOES put an asterisk on the CustomerOrderNumber field - but it doesn't spawn an error upon save if that field is empty.

Another issue is my PXSelect to get the record out of SOOrderType ALWAYS returns a null for the check box user field, even if it has a 'True' value in the database (which is why I put the ternary operator on the call). Even if I hard-code a 'true' value in the PXUIFieldAttribute.SetRequired call, it still doesn't spawn the error to prevent a save. The asterisk is there, but it doesn't work.

If I use a Cache_Attached event to add [PXDefault] it works perfectly - but this doesn't help me - I need it conditionally set.

Any ideas?

Required is used only for displaying the asterisk. PXDefault attribute is the one that makes the field mandatory based on PersistingCheck property value.

The issue is that PXUIFieldAttributes like PersistingCheck can only be set once at the time of graph creation. You can set it dynamically in the constructor/Initialize method but if you change the property after that it has no effects.

When I need a field to be mandatory based on a dynamic condition I remove the PXDefault attribute and validate the field manually in event handlers like RowPersisting:

public void PMTimeActivity_RowPersisting(PXCache sender, PXRowPersistingEventArgs e)
{
    PMTimeActivity timeActivity = e.Row as PMTimeActivity;

    if (timeActivity != null && PMTimeActivity.timeSpent == null)
    {
        PXUIFieldAttribute.SetError<PMTimeActivity.timeSpent>(sender, timeActivity, "'Time Spent' cannot be empty."));
    }
}
