Question

Guys, I can’t seem to get the object serialization working correctly clientside for my app? When I used the getJSON() method inside jQuery with a response mime type of text/json (serialized using JSON.Net library), it was working fine, but as soon as I moved it across to an ajax() request (so I could post my code in webmethods on my page) its fallen apart. Any ideas would be greatly appreciated.

Edit: I’m using framework 2.0, not 3.5

My javascript looks like this:

    function companySearch(txt)      {         $('#<%= divCompanyResult.ClientID %>').hide();         $('#<%= divCompanyResult.ClientID %>').html('');          var strCompanySearch = $('#<%= tbCompanySearch.ClientID %>').val();          $.ajax         ({             type: 'POST',             url: 'Home.aspx/GetCompanies',              contentType: 'application/json; charset=utf-8',              datatype: 'json',             data: '{name: '' + strCompanySearch + ''} ',              success: companySearchSuccess,             error: onError         });          return (true);     }      function companySearchSuccess(response)     {         $.each(response,              function(i, company)              {                 $('#<%= divCompanyResult.ClientID %>').prepend(company.Name + '<br />');             });          $('#<%= divCompanyResult.ClientID %>').slideDown(1000);     } 

And my .ASPX page (nb. its a page, not a webservice), looks like this:

    [WebMethod]     public static Company[] GetCompanies(string name)     {         Company[] companies = Company.FindCompanies(name);          return companies;     } 

And the object its returning:

[ActiveRecord] public class Company : ActiveRecordBase<Company> {     private int iD;     private string name;     private string accountNo;     private string streetAddr1;     private string streetAddr2;     private string streetSuburb;     private string streetCity;     private string postAddr1;     private string postAddr2;     private string postSuburb;     private string postState;     private string postPC;     private string accountType;     private string accountSubType;     private string areaRep;     private string status;     private string overview;     private string bpcsId;     private string modifiedBy;     private DateTime modifiedDate;     private IList<Contact> contacts;      [PrimaryKey]     public int ID { get { return this.iD; } set { this.iD = value; } }     [Property]     public string Name { get { return this.name; } set { this.name = value; } }     [Property]     public string AccountNo { get { return this.accountNo; } set { this.accountNo = value; } }     [Property]     public string StreetAddr1 { get { return this.streetAddr1; } set { this.streetAddr1 = value; } }     [Property]     public string StreetAddr2 { get { return this.streetAddr2; } set { this.streetAddr2 = value; } }     [Property]     public string StreetSuburb { get { return this.streetSuburb; } set { this.streetSuburb = value; } }     [Property]     public string StreetState { get { return this.streetCity; } set { this.streetCity = value; } }     [Property]     public string StreetPC { get { return this.streetCity; } set { this.streetCity = value; } }     [Property]     public string PostAddr1 { get { return this.postAddr1; } set { this.postAddr1 = value; } }     [Property]     public string PostAddr2 { get { return this.postAddr2; } set { this.postAddr2 = value; } }     [Property]     public string PostSuburb { get { return this.postSuburb; } set { this.postSuburb = value; } }     [Property]     public string PostState { get { return this.postState; } set { this.postState = value; } }     [Property]     public string PostPC { get { return this.postPC; } set { this.postPC = value; } }     [Property]     public string AccountType { get { return this.accountType; } set { this.accountType = value; } }     [Property]     public string AccountSubType { get { return this.accountSubType; } set { this.accountSubType = value; } }     [Property]     public string AreaRep { get { return this.areaRep; } set { this.areaRep = value; } }     [Property]     public string Status { get { return this.status; } set { this.status = value; } }     [Property]     public string Overview { get { return this.overview; } set { this.overview = value; } }     [Property]     public string BPCSId { get { return this.bpcsId; } set { this.bpcsId = value; } }     [Property]     public string ModifiedBy { get { return this.modifiedBy; } set { this.modifiedBy = value; } }     [Property]     public DateTime ModifiedDate { get { return this.modifiedDate; } set { this.modifiedDate = value; } }      // Inverse ensures is read-only ie. Contact controls the relationship     // Castle will usually infer relationship, but we explicitly set just to be on the safe side     [HasMany(Inverse=true, Table='Contact', ColumnKey='CompanyId')]      [ScriptIgnore]     public IList<Contact> Contacts { get { return this.contacts; } set { this.contacts = value; } }      protected Company() { }      public Company(string Name, string StreetAddr1)     {         this.Name = Name;         this.StreetAddr1 = StreetAddr1;          ModifiedBy = 'Test';         ModifiedDate = DateTime.Now;     }      public static Company[] FindCompanies(string name)     {         return FindAll(Expression.InsensitiveLike('Name', '%' + name + '%'));     }  }

Turns out I had overlooked the camel casing for the dataType property on my ajax request

Old:

    $.ajax     ({         type: 'POST',         url: 'Home.aspx/GetCompanies',          contentType: 'application/json; charset=utf-8',          datatype: 'json',         data: '{name: '' + strCompanySearch + ''} ',          success: companySearchSuccess,         error: onError     }); 

Solution

    $.ajax     ({         type: 'POST',         url: 'Home.aspx/GetCompanies',          contentType: 'application/json; charset=utf-8',          dataType: 'json',         data: '{name: '' + strCompanySearch + ''} ',          success: companySearchSuccess,         error: onError     }); 

Hope this helps others avoid the hours of searching google, tutorials and blogs that I suffered… Doh!
