Calling Linq To SQL Method In Web Service With JQuery?
Jan 24, 2010
I have a test web service called: MySimpleService.svc with a method called:GetUserNamesByInitials. below is the Linq to SQL code:
[OperationContract]
public static string GetUserNamesByInitials(string initials)
{
string result = ""; [code]...
what I do is to type the user id in one textbox (TextBox3) and when I press the Tab key the result is shown in another textbox(TextBox4).
The jQuery call works well with other methods that do not call the database, for example using this other web service method it works:
[OperationContract] public string ParameterizedConnectionTest(string word)
{
return string.Format("You entered the word: {0}", word);
}
However with the Linq method it just does not work.
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
web service method(getMainHeads) with parameter is not calling with auto complete text box extender(same method with out parameter is calling fine). My Service is
[System.Web.Script.Services. ScriptService] public class InvService : System.Web.Services.WebService { ItemMainHeadMsts objItemMainHeadMsts; DatabaseHelper objDataHelper; [WebMethod] public string[] GetMainHeads(string value) { List<string> oList = new List<string >(); objItemMainHeadMsts = new ItemMainHeadMsts (); objDataHelper = new DatabaseHelper (); objItemMainHeadMsts = ItemMainHeadMstBase.SelectByFieldAuto("IMHDesc" , value); foreach (ItemMainHeadMst mainHead in objItemMainHeadMsts) { oList.Add(mainHead.IMHDesc); } return oList.ToArray();..........................
I have a web service that has a CreateReport method that generates a report based on the specified criteria.
When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.
When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.
When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.
I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.
I am in the process of implementing jQuery calling WCF service which is hosted in the same domain. My application uses Win Auth that works fine with ASP.NET app. I would like to know from the team if the user calls the WCF service from the ASP.NET what is the security context in which the service runs? Or it uses the web.config security which is specified? Are there any links related to this where i can get some information.
ASP.NET 4.0, jQuery and WCF 4.0 in same web application
[ServiceContract] public interface IService1 { [OperationContract] string GetData(int value); // TODO: Add your service operations here } public class Service1 : IService1 { public string GetData(int value) { return string.Format("You entered: {0}", value); } }
the following call is working
protected void Button1_Click(object sender, EventArgs e) { ServiceReference1.Service1Client p = new ServiceReference1.Service1Client(); Label1.Text= p.GetData(5); }
but when I am trying to call it from jquery its not working
I have created a webUserControl timer.ascx, I have a page showTime.aspx I have added timer.ascx into ShowTime.aspx on drodown change I want to display the current time.

I'm trying to call an action method in an MVC application using jQuery. Basically what I want is to take the value of a couple of input fields and call the action method by clicking a button, passing the values of the input fields as parameters. But I only get the value of the "number" parameter, not the "year" parameter.
function selectWeek() { $('#selectWeekButton').click(function (event) { var number = $("#selectWeekId").val(); [code]...
I checked the url with an alert, as you can see, and it seems to contain both values fine. But when I check the value of the year parameter in the action method it is null.Here are the input fields:
public ActionResult Edit(string number, string year) //etc...
I know that this looks like a strange thing to do instead of just binding fields, but the reason is that these input fields and their values is not the main purpose of this View. They're just there to select another week in this timesheet application. And besides, I'm going to replace the input fields with a jQuery calendar eventually, so I will still have to do something like this.
So what's the easiest way to do this, and why isn't it working as it is?
I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0; var _currentSeconds = 0; function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID); [code]...

I have double checked the url of the service and spelling/case of the name of the method as well as the parameters in the dataStr.
I still get the error-<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.
I'm trying to implement a view tracking web service on my website. I'm using JavaScript because I want to exclude any search bots from my tracked views. The problem is I'm getting a "Unknown web method" error when I try to use jQuery to post to the web service I've created.
$(document).ready(function() {
$.ajax({ type: "POST", [code]...
The error is an ASP .NET error: Unknown web method TrackItemView. Parameter name: methodName.I've done this hundreds of times (seemingly), but I just can't see what I'm missing. I'm sure it's something small...

I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer) en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams) en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters) en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams) en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
