WCF Interface:

[OperationContract(Name = "GetPropertyInformationForGrid")]

[WebInvoke(Method = "GET",

BodyStyle = WebMessageBodyStyle.Wrapped,

ResponseFormat = WebMessageFormat.Json)]

List<vc.PropertyInformation> GetPropertyInformationForGrid(int startIndex, int rowCount);

[OperationContract(Name = "GetPropertyCount")]

[WebInvoke(Method = "GET",

BodyStyle = WebMessageBodyStyle.Wrapped,

ResponseFormat = WebMessageFormat.Json)]

int GetPropertyCount();

Result calling GetPropertyCount() from browser:

{"GetPropertyCountResult":3}

Result calling GetPropertyInformationForGrid() from browser:
 

{"GetPropertyInformationForGridResult":[{"BasementSize":0,"DateCreated":null,"ElapsedDays":null,"Gross":0,"LotSize":0,"Net":0,"Payout":0,"PostCodeIdentifier":null,"Price":1000,"PriceDevelopment":null,"PropertyType":0,"Rooms":0,"Size":0,"SqmPrice":0,"StreetBuildingIdentifier":null,"StreetName":null,"YearBuilt":0},{"BasementSize":0,"DateCreated":null,"ElapsedDays":null,"Gross":0,"LotSize":0,"Net":0,"Payout":0,"PostCodeIdentifier":null,"Price":1700,"PriceDevelopment":null,"PropertyType":0,"Rooms":0,"Size":0,"SqmPrice":0,"StreetBuildingIdentifier":null,"StreetName":null,"YearBuilt":0},{"BasementSize":0,"DateCreated":null,"ElapsedDays":null,"Gross":0,"LotSize":0,"Net":0,"Payout":0,"PostCodeIdentifier":null,"Price":900,"PriceDevelopment":null,"PropertyType":0,"Rooms":0,"Size":0,"SqmPrice":0,"StreetBuildingIdentifier":null,"StreetName":null,"YearBuilt":0}]}

Nothing happens. No data in my grid. I hope this is enough information for somebody to point me in the right direction.

Hello Martin,

Can you please try applying the following attribute on your OperationContract's instead:

[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.WrappedRequest,
ResponseFormat = WebMessageFormat.Json)]

This should help.

Sincerely yours,
Nikolay
