asp.net - Problem passing JSON data using jQuery $.ajax() to .NET MVC Action w/ custom BindingModel -

-

I am trying to use JSON data from ASP.NET MVC action from client browser using jquery $ .ajax () I am Tie this to a .NET class using a custom ModelBinder

Client JavaScript: .. Click on 

  $ ('# btnPatientSearch') (function {} {var patientFilter = {last name: 'flinstone', first name: 'fred'}; json.data = $ .toJSON (PatientFilter); $ .ajax ({url: '/ service / GetPatientList', type: 'received', cache: false, data: JsonData, contentType: 'application / json; charset = utf-8', data type: 'Json', timeout: 10000, error: function () {warning (error loading JSON = '+ jsonData);}, success: function jsonData) {$ ("# patientSearchList") fillSelect (jsonData);}}} ;

.NET class for JSON data 

  [ModelBlinder (typef (JSONmodebanker)) Public class petit filter {#region properties public string IDNumber {get; Set;} publ ic string firstname {received; Set; } Public String LastName {get; Set; } Public string SSN {get; Set; } Public Date Time DOB (Receive); Set; } #MessageContent

MVC action 

  Public JsonResult GetPatientList (iPatientDoc.Models.PatientFilter patientFilter) {

custom MODELBINDER 

  public class JsonModelBinder: IModelBinder {#region IModelBinder member throw public object BindModel (ControllerContext controllerContext, ModelBindingContext bindingContext) {if (controllerContext == null) new ArgumentNullException ( "controllerContext"); If (binding contact == empty) remove the new logic ("Binding Contains"); Var Serializer = New Data ContrastJason Serializer (Binding Contax Model Type); Return Serializer. ReadObject (Controller Consort ..httcx RequestInststream); #endregion}}

Custom ModelBinder no data is correctly stated, however Request.InputStream is left blank, to force PatientFilter object.

Any thoughts appreciated. Chris

Some thoughts on this

  • You use a GET request I think the request body is always empty for GET
  • Your Patient Filter class has no [DataContract] attribute. I'm not sure that it will do anything serial
  • I'll have your $. Ajax () is not sure about the call. I expected that the data option would take an object instead of just a JSON string. After watching, I will try to set the process data option incorrectly.

There is also an interesting explanation for the data option:

The data must be sent to the server. This query is converted to a string, if there is no string already. See processData options to prevent this automatic processing has been added to the URL for GET-requests. The object key / value must be added. If the value is an array, then sorting multiple values ​​with the same value of jQuery. {Foo: ["bar1", "bar2"]} '& amp; Foo = bar1and Foo = bar2 '.

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
