Hello Manish 1. I am working on Winform and not ASP .Net 2. I am not on reading and writing xml where we have many options when we google. My requirement is different. Only first col should do a verification with the xml. Each number above is a different question. Thanks for trying to help me

Look at the DatagridView.CellEndEditEvent. It will fire at the moment that one of the cells is edited and has lost the focus. In the event handler read the values from the grid validate and do your calculations.
