You have a data-type mismatch. The json sent from the client-side and Detail type on the server-side code do not match. The error is due to the server-side code getting an apostrophe/quote character (\u0027) in the serialized json while it is expecting an array.

You mentioned this
  [System.Web.Services.WebMethod]
         public static Detail DatatCity(Detail AllRequests)
Can you show us how your Detail class is defined?

             // by the way as a result you could also return a strongly

From the code you shared, since you have this URL:
"/rees.aspx/DatatCity"

Open in new window

and this json
{"AllRequests":[{"Company":"Company","Total":"45",...

Open in new window

you need to have an array of some type for the AllRequests parameter.
public static Detail DatatCity(Detail[] AllRequests)

Open in new window

And the Detail class here should have public properties for the json you send, such as Company, Total, Inventory and so on.

Is your url for the AJAX call now
"/rees.aspx/AddClient"
instead of
"/rees.aspx/DatatCity"
?

That part is correct. AddClient is the one I am using. the post in the dom is the json string trying to post. the method will not take it.
