From: redbull on 2 Jul 2010 06:42 Hi guys, I've created a simple webpage with a datagridview, my business object. If i try to modify a record i get an error on date value: Dettagli eccezione: System.InvalidOperationException: Impossible to convert the value of parameter 'DataNascita' from 'System.String' to 'System.DateTime'. What should I do? Thanks

The string date and time must be converted over to System.Datetime before the field or variable can be populated by string data the represents a date and time. You should look up how to use the 'Convert' statement.
