      • Problem: I am using C# to create a (hopefully) simple UI to access data stored in 1 table. I created the DataSource and a DataGrid. I then dropped the datasource on the grid and Visual Studio helpfully created all the controls that I need. However, the table contains columns that do not allow null. How can I trap the fact that an inserted row contains a column with a null value Thank you i

Why the Load method throws XmlSchemaValidationException i think it's Validate method's responsibility to throw XmlSchemaValid
