I check using web service that we can invoke. So, I use web method at code behind like below
[WebMethod]public static string ReceiveWebService(string type_list, string type_accom){
return string.Format("Thank you ,{0} number of rows inserted!", rowsInserted);}
And check user session at load like below
if (Session["user"] == "Abhijit"){}else{Response.Redirect("Login.aspx");}
Is this process secure?

HWhen I want to use AJAX, primarily with JQuery .ajax function, I use functions within the .aspx.cs of the same page with [WebMethod].
I dont like this method very much because everyone can tell which function I use, and with no problem they can use it too.
My guess is that theres a better way to do this, Am I right?

I am using a webform and trying to use a $.ajax call a webmethod on my code behind to format and return some data. It sounded easy but I need the help of an expert. Here is what I have and perhaps someone could steer me in the right direction to solving this problem. for the time being all I want the [webmethod] to return is some dummy data so the jqgrid displays, after I get it displaying correctly I will work on the data column format. So for this sample to work correctly user would open web from and click on button "Load Grid" when this is clicked it calls the the [webmethod] on the server, the sever then gets the data and passes it back to the jquery .ajax call and then it gets loaded into the jqGrid.
[Code]....
and the codebehind
[Code]....

I am trying to implement your code in "Calling ASP.Net WebMethod using jQuery AJAX", but the alert is giving me the value "Undefined".
I believe my website (asp.net c#) is not correctely configured for webmethods.

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 have been successful in making an Ajax call to get the data and then setting up the JQGrid with local data. I think its an extra step in the setup process and that I should be able to provide the path to the webmethod using the url property. The editurl property is the same way. I am never actually receiving the post to the server. Attempted JQGrid Setup
function GetData()
{
$('#list').jqGrid({
type: "POST",
url: "Default.aspx/GetUsersJSON",
datatype: "json",
height: 250,
colName: ['Username', 'Email'],
colModel: [
...
}).jqGrid(
'navGrid',
'#pager',
{
edit: true,
add: true,
del: true
});
}
WebMethod
[WebMethod]
public static string GetUsersJSON()
{
var users = new List();
using(UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext())
{
users = uasd.GetUserList();
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(users);
}
Current Code I got it working correctly now, but I still have one final question. Why did I have to set the 'repeatitems: false' in order to display the content? Some of the caveats to get this to work include the different ways to setup the ajax request. (Ajax: type) is (jqgrid : mtype) (Ajax: contentType) is (jqgrid : ajaxGridOptions: { contentType: })
And finally understanding the documentation from the documentation on how to setup the JSONReader.
function GetUserDataFromServer()
{
$('#list').jqGrid({
url: "Default.aspx/GetUsersJSON",
mtype: 'POST',
ajaxGridOptions: { contentType: "application/json" },
datatype: "json",
serializeGridData: function (postData)
{
return JSON.stringify(postData);
},
jsonReader: {
root: function (obj) { return obj.d; },
page: function (obj) { return 1; },
total: function (obj) { return 1; },
records: function (obj) { return obj.d.length; },
id:'0',
cell:'',
repeatitems: false
},
datatype: "json",
height: 250,
colName: ['Username', 'Email'],
colModel: [
{
name: 'Username',
index: 'Username',
width: 100,
editable: true
},
{
name: 'Email',
index: 'Email',
width: 220,
editable: true
},
{
name: 'IsLockedOut',
index: 'IsLockedOut',
width: 100,
editable: true,
edittype: 'checkbox'
}
],
caption: "Users"
})
}
Web Method
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static List GetUsersJSON()
{
using (UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext())
{
return uasd.GetUserList();
}
}
One JSON Object from the List
{"__type":"UserAdministrationSandbox.UserData","PKID":"00000000-0000-0000-0000-000000000001","Username":"TestUser","ApplicationName":"Test","Email":"TestUser@test.com","Comment":"TestUser","Password":"D41D8CD98F00B204E9800998ECF8427E","PasswordQuestion":"Is this a blank Password?","PasswordAnswer":null,"IsApproved":true,"LastActivityDate":"/Date(1298869200000)/","LastLoginDate":"/Date(1298869200000)/","LastPasswordChangedDate":"/Date(1298869200000)/","CreationDate":"/Date(1298869200000)/","IsOnLine":false,"IsLockedOut":false,"LastLockedOutDate":"/Date(1298869200000)/","FailedPasswordAttemptCount":0,"FailedPasswordAttemptWindowStart":null,"FailedPasswordAnswerAttemptCount":null,"FailedPasswordAnswerAttemptWindowStart":null}

I have a web Method in my C# that is called via Jquery ajax method. The web method should return an object back to the Jquery which will be used to populate. I have tried returning a JsonResult object, the actual object and nothing seems to work! I'm not using MVC (Unfortunately). Is there a way that I can return an object from my web method which can be used by my AJAX method? here is the link for my JQuery AJAX method [URL]

I use this test code and it works well :
JQuery
$(document).ready(function () {
$("#Result").click(function () {
$.ajax({
type: "POST",
url: "test-JQuery-Page-Methods.aspx/GetInfo",
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$("#Label1").text(msg.d);
}
});
});
});
.VB
<WebMethod()> Public Shared Function GetInfo() As String
Return "test"
End Function
Now i try to pass an argument to the function but something is wrong in my code and i dont know what is wrong... :
JQuery
$(document).ready(function () {
$("#Result").click(function () {
var textj = 'test';
var jsonText = JSON.stringify(textj);
$.ajax({
type: "POST",
url: "test-JQuery-Page-Methods.aspx/GetInfo",
data: jsonText,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$("#Label1").text(msg.d);
}
});
});
});
.VB
<WebMethod()> Public Shared Function GetInfo(ByVal infostring As String) As String
Return infostring

I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.
JavaScript Code:
$.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) { console.log(msg.d);}});
C# Code:
[WebMethod]public static object GetStuff(string a, int b){ }
Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.

I have an Ajax function called from JQuery that goes to a webservice to return a value. I need a SIMPLE example on how I can do this. I've been going nuts with serializing and every other aspect of this topic. I need to return either an ArrayList with ONE string field or a DataTable of some kind. Either way, I'm populating it into a DropDownList. I'm willing to consider alternatives to this idea. (Background info - I get a value from a textbox and I need to run it through a DB to get an associated value or set of values). I'm being really general so that someone can show a simple example.

I have seen that ASP .Net Code Behind files are really slow. I have used local web services which i call from jquery ajax function and they are fast. But i am still confused? Should i display dynamic data from code behind or web services?
I let my web service return a JSON Object and i assign relevant elements from that JSON object to different html elements like (image, div etc.)
