Passing Complex Data Types in ASP.NET Ajax | 4

Register the Web Service and Scripts

Next, we need to use a ScriptManager control to register the Web service and the scripts we will use. You can then use JavaScript to call the Web method that returns the necessary data for the Customer class we created earlier.

function getCustomerData() { MyWebService.GetCustomerData(OnSucceeded, OnFailed, userContext) }

The OnSucceeded and OnFailed methods would be called on the success or failure (respectively) of the Web method call.

function OnSucceeded(result, userContext, methodName) { } function OnFailed(exception, userContext, methodName) { }
