The Kettic Data Grid View allows users of the control easily validate data grid cells when data is committed to the data source.

Before we validate data to grid cell, we need to cancel the Validate Cell event to prevent the users from exiting the cell until entering a valid editor value or cancelling the edit process.

Meanwhile, we can use the Validate Row event in the same way to prevent the user from exiting the current row.

The binding of the grid happens on the Row Data Bound Event, that is why we assign a validation group to the controls present in each row inside in the Row Data Bound event.

Before fetching the records into gridview, check for the null values through the query.

I think you should start a new page and test with a much smaller case scenario and get that working first. If you still need help with that smaller page, post it for help - it will be easier for us to understand it.
