I had a dataset with one table wich contained some null fields; this dataset was send to client and then untouched back to server and I received an error like this: "Cannot set the Column "ColumnName". Use DBNull instead.
I solved it fast creating my custom datatable converter derived from DataTableConverter changing row[i] = JavaScriptDeserializer.Deserialize((IJavaScriptObject)cols[i], dt.Columns[i].DataType); to object obj = JavaScriptDeserializer.Deserialize((IJavaScriptObject)cols[i], dt.Columns[i].DataType); row[i] = (obj == null) ? DBNull.Value : obj; --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ajax.NET Professional" group.
