[Alain Rodríguez Cuello]

Hi,

When i change column.ExtendedProperties, DataSet.GetXmlSchema:


DataSet ds = new DataSet("REGISTERS");

                        ds.Tables.Add("Table1");

                        ds.Tables["Table1"].Columns..Add("column1",typeof(System.String));

                        ds.Tables["Table1"].Columns..Add("column2",typeof(System.String));

                        

/* Without next two line program it run Ok*/

                        ds.Tables[0].Columns[0].MaxLength = 10;

                        ds.Tables[0].Columns[1].MaxLength = 10;

                        

                        ds.Tables["Table1"].Rows.Add("Alain", "Ramirez");

                        

                        ds.AcceptChanges();

                        ds.WriteXml("/tmp/Alain.xml",XmlWriteMode.WriteSchema);

                        

                        ds.ExtendedProperties.Add("test1","x1x");

                        ds.WriteXml("/tmp/Alain.xml",XmlWriteMode.WriteSchema);  /* OK */

                        ds.Tables[0].ExtendedProperties.Add("test2","1x1");

                        ds.WriteXml("/tmp/Alain.xml",XmlWriteMode.WriteSchema);  /* OK */

                        ds.Tables[0].Columns[0].ExtendedProperties.Add("test3","xxx");

                        ds.WriteXml("/tmp/Alain.xml",XmlWriteMode.WriteSchema); /* FAIL */
