I'm passing a value from a JQuery to the serverside & now i have to update with the database by looping through all the datalist items...
JQuery:
PageMethods.addRoomAndBed(empname,Number(roomId));
C#:
[WebMethod]
public static string addRoomAndBed(string name, int dutyid)
{
// MANIPULATE DATALIST AND UPDATE DATABASE HERE
return null ;
}
I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
[Code]....
my page Evaluation.aspx has this code
[Code]....
and I am calling the webmethod by javascript like this
[Code]....
The result is, I get the error function running and I get "undefined error" alert.Am I calling the procedure correctly? I put a breakpoint on the webmethod and it.
I've a problem: I've a GridView, with a folder structure, and an asp.net checkbox for each row in the gridview.Now, when the user clicks the delete button, it should delete all the folder entities where the user checked the checkbox.The problem is, there may not be a postback...So I used to use findcontrol in an ordinary asp.net button codebehind, but in a webmethod, it's impossible to access the page object, because WebMethods need to be static...Now I tried ctype(httprequest.current.request.handler,page) but that doesn't seem to work...
How can I get the page object to use findcontrol ?
Within a WebMethod I need to access a Page Property. The code is generating an error:
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class
Is it possible to access page properties from WebMethods?
Here's my code:

I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
I have a webmethod named (abc), inside this webmethod code i want to redirect to another webform and i am using this code.
HttpContext.Current.Response.Redirect("../paypal_redirect.aspx",false);
But this code is not working. How to redirect to another page from webmethod.
I have this function in aspx page.

and I call this function from JavaScript as below:

I want to know what is this technique called and what is the advantage of calling the function on that way
Looking for sample to access the hidden variable which is declared in the aspx page in the webmethod.
View 1 RepliesI found this Article from link : [URL] .... that explains how to call server-side Method from javascript,
I used your code, my server-side function is static, public, and also I added
[System.Web.Services.WebMethod]
and
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
I have added aiax ModalPopupExtender on a web page
<ajaxToolkit:ModalPopupExtender
ID="ModalPopupExtender1"runat="server"[code]....
to fetch data to popup control dynamically I used webservice [WebMethod]public string getIssueDetails(string contextKey){ } But before that I set ModalPopupExtender1.DynamicContextKey = "1_1_60"; in code behind.But problem is in webmethod "contextKey" is getting passed as null.
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 want to send single json object with nested arrays through jquery ajax method.
In Code
In jquery ajax i am passing LeaveRuleMaster a single json object which holds some properties (Leavetypeid, Leavename, Leavestatus and nested array LeaveRulespecific.
In vb.net code i can receive the value of properties(Leavetypeid,Leavename,Leavestatus)
but i am receiving the LeaveRuleSpecific as nothing.
Based on the following link i tried this [URL] .....

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

I would like to write some html content to div element through web method. The web method should be like
[System.Web.Services.WebMethod]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public static string LoadImages1()
{
[Code]....
without passing data to success block, I have to write at webmethod it self.
I am trying to create a function that when a button is clicked it will pass all my records to my json page which will save my data. This is what i have so far
var t = this;
t.RecordsSave = function ($http) {
for (var i = 0; i <t.records.length; i++) {
var record=t.recordss[i];
var data = params( {
record: record.Number[i],
[Code] ....
I get the following error "params is not defined"
and "Cannot read property '0' of undefined"
How should i go about this. not familiar with angular js
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.
My problem is that I have a jqury function basically I want to add gridview row into data base .so that pupose I am doing that by accessing webmethod ,but the web method can’t call from that code .
My data can’t save into data base I will check it.value should be passed but problem is that this function can’t call webmethod I will check it doing debudg.
my function should be call webmethod
Following my code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" type="text/javascript"> </script>
<script type="text/javascript">

i have used AjaxToolkit:AutoCompleteExtender, which calls a web method to get string array. Everything was working fine as its populating all the data.But the issue arise when web method is returning value in a string array like
arr[0]=1-12-100
arr[1]=1-10-100
the value im getting in the AutoCompleteExtender is the subtract of the result like
arr[0]=-111
arr[1]=-109
Why is it treating it like numeric and doing calculation when the return type is actual an string. i think its has to do sth with serialize and deserialize thing
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"
})
}

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]
View 1 RepliesI 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);

Have try to send the complex string that is created(serilize) from data.If I write just a regular string there is no problem but I want to sendover the array data as a string and then deserilize it does not work.What happens is that the webmethod 'save' never start.
