由 无人久伴 提交于 2019-11-27 13:57:13

The length of the string exceeds the value set on the maxJsonLength property. Changing the length of the maxJsonLength attribute in Web.config like this does not help. <configuration> <system.web.extensions> <scripting> <webServices> <jsonSerialization

It works if I accept the inputs as separate parameters: [WebMethod] public static Address GetJSonAddress(string name, string street) But if I try to take it as an object it does not work, what gets passed in is simply null: [WebMethod] public static Address GetJSonAddress(Address newAddress) I have tried Webmethods, Pagemethods, WCF using DataContractJsonSerializer...nothing. The Address class is decorated appropriately with Datamember/DataContract. The properties are

JQGrid - Cannot call ASP.NET WebMethod but can with Ajax

由 依然范特西╮ 提交于 2019-11-27 03:36:45
问题 I am new to jqGrid and I have found it difficult to follow the documentation jqGrid Documentation I cannot figure out how to call a WebMethod when setting up the JQGrid.

I am never actually receiving the post to the

Trying to make Web Method Asynchronous

由 不羁的心 提交于 2019-11-26 16:48:32
