    <p>Got a question. I get this error and I know it is due to the fact that int32 has a number limit of 2147483647. But I don't know why I am getting this error when the value in question (a telephone number of 11 digits) is defined as a string in our SQL database, a string in our web service and a string in our web application.</p> <p>I assume it is something to do with the way the service serialises and deserialises data over a connection, but I was wanting to know if there is a way to force Number to use only the string instead of parsing it when deserialisation happens. Or even get it to parse as int64.</p> <p>Here is the error exception. I removed the namespace and service name. It is the property Number that is causing the problem.</p> <blockquote> <p>There was an error deserializing the object of type .".ClientPhone[]. The value '07721545554' cannot be parsed as the type 'Int32'."</p> </blockquote> <p>And here is the code for the service and the service interface.</p> <pre><code>[DataContract] public class ClientPhone { [DataMember] public int? ClientNumberID { get; set; } [DataMember] public int? RefID { get; set; } [DataMember] public string Number { get; set; } [DataMember] public string NumberType { get; set; } [DataMember] public bool? PrimaryNumber { get; set; } } public partial class ClientNumberEntity { public int ClientNumbersID { get; set; } public Nullable&lt;int&gt; RefID { get; set; } public string ClientNumberType { get; set; } public string ClientNumber { get; set; } public Nullable&lt;bool&gt; PrimaryNumber { get; set; } public virtual ClientDataEntity ClientData { get; set; } } public List&lt;ClientPhone&gt; GetClientsPhoneByReference(int _reference) { OurDatabaseEntities context = new OurDatabaseEntities(); var phoneEntity = (from c in context.ClientNumberEntities where c.RefID == _reference select c).ToList(); if (phoneEntity != null) { return TranslateClientPhoneEntityToPhoneNumberList(phoneEntity); } else throw new Exception("Unable to get phone data"); } private List&lt;ClientPhone&gt; TranslateClientPhoneEntityToPhoneNumberList(List&lt;ClientNumberEntity&gt; numberEntities) { List&lt;ClientPhone&gt; phoneList = new List&lt;ClientPhone&gt;(); foreach (ClientNumberEntity numberEntity in numberEntities) { ClientPhone phoneListMember = new ClientPhone(); phoneListMember.ClientNumberID = numberEntity.ClientNumbersID; phoneListMember.RefID = numberEntity.RefID; phoneListMember.Number = numberEntity.ClientNumber; phoneListMember.NumberType = numberEntity.ClientNumberType; phoneListMember.PrimaryNumber = numberEntity.PrimaryNumber; phoneList.Add(phoneListMember); } return phoneList; } </code></pre> <p>Any advice on a solution would be greatly appreciated! Thanks :)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
