How are informational/warning/error messages generated and displayed for rows in a grid

Hi Jini, thank you so much for your response!  I did already try using the FieldVerifying event, but when I debug my program, this event is never executed. The program I wrote is designed as an Inquiry, so the user only DISPLAYS the grid rows. How can you make the FieldVerifying event execute when the data view rows are being loaded?

Hi Naveen, thank you for your feedback. I changed the event handler to RowSelected, and the event handler is now executing, when the grid rows are being initially displayed to the grid. Here is the handling logic:

       protected void BOMComponentData_RowSelected(PXCache sender, PXRowSelectedEventArgs e)

        {

            BOMComponentData row = e.Row as BOMComponentData;

            if (row != null  &&

                row.ExpectedQty != null && row.TotalQtyReq != null &&

                row.ExpectedQty < row.TotalQtyReq)

            {

                sender.RaiseExceptionHandling<BOMComponentData.totalQtyReq>(

                    row,

                    row.TotalQtyReq,

                    new PXSetPropertyException(Messages.QtyExceedsExpected,

                    PXErrorLevel.Warning));

            }

        }

The RaiseExceptionHandling block IS executing when the row conditions are met, BUT no messages are being displayed to the grid row on the ASPX page.  

Here is the source for the ASPX page:
