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.
What solution is better? - For server load. - For quick loading pages
1) Use a timer from VS2008, set the timer for three seconds.Use UpdatePanel and Triggers.In Timer_Tick write code for the application.
2) Create a WebMethod, where to write the application code.And using javascript to load a Web method and use - window.setInterval (callMethod () ', 3000).
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.
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 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 have 2 web pages edit.aspx and webmethods.apx. In edit.aspx there is some jquery code to get some data :
[Code]....
With this I try to get a Json object from the webmethods.aspx page :
[Code]....
I get an error back that says "Parser Error", I even did put an breakpoint on the webmethod but it is like it's never triggered. Is my url wrong if I'm in the following url :
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.
Right now it reports the following error: "Cannot locate the resource". I figure that I am specifying the url incorrectly. This javascript is in an external file located in the same directory as Default.aspx .
I am trying to make a jquery ajax call to a static method on the codebehind file. The problem is that ArtistManager injected by Spring is not static and I cannot use it in the static webmethod. I am looking for any ideas on how to implement this
I want to call MsCaptcha Control in Static WebMethod,for validating. so,I want to check mscaptcha value in javascript or jquery without refresh the page.I think it is my solution that i use JqueryAjax.
i manage to add recrod via jquery ajax call to webmethod but i want to update the dropdown list once the record is been added. i dont want to use update panel. what would be the best way of doing that.
I want to use same functionality in Ajax:Accordion. Looking for the code for this as well as instead of label in user control i want to bind the grid view.
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).
At present I am using ajax:TabContainer for the tabs. As you know that does not do Lazy loading. Can sonone give me links to or some code examples to do Tabs with Lazy loading. I know that the Jquery tabs do lazy loading but there are no complete examples on the web which tells you on how to do lazy loading with JQuery tabs.
