Forms Data Controls :: Getting Data Does Not Correspond To Valid JSON Error?

Apr 14, 2010

I have an Infragistics WebDataGrid on a user control. I add that user control programmatically to an UpdatePanel on a Content Form. Everything works great. I get data in the grid just fine. However, when I go to click any of the grid functions (Sort, Filter, Page, etc.) it throws a Sys.ArgumentException in one of the ScriptResource.axd dynamic files.

Here is the error:

"Microsoft JScript runtime error: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data"

It stops in the following function:

I read about other people having this issue and they said it was due to dates or due to double quotes ("") being in strings? I am binding this datagrid to an Entity Data Framework object query like this.

AJAX :: Unable To Make Wcf JSON Ajax Service Work Through Http Like Asmx?

Jun 22, 2010

I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.


When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."

But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:

WCFCompanyService Service

You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:

svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl

This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:

C#

class Test { static void Main() { HelloClient client = new HelloClient();

[Code]....

This is my Ajax-enabled WCF service code:

[Code]....

This is the web.config service model setting
