AJAX :: Calling A Regular Method From Within A Web Method?
Nov 1, 2010
i have a web service that i use for the AutoCompleteExtender, let the below code show you what i'm trying to do: [Code]....
this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?
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?
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.

This type of page is not served. Description: The type of page you have requested is not served because it has been explicitly forbidden.
I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.
If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired.
Below is my code and the order I need it to fire.
[WebMethod] public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category) { StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues); int CategoryID;
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
I get this error "The server method xxx timed out." calling a WebService that internally does a hard query to the database, and takes some time. I use this method to change the webservice timeout, but it does not seems to do anything (the timeout errors appears in less than a second). MyService.set_timeout(100000);
I have a page with an update contentpanel, with 4 panels inside. Image buttons outside the update panel control control which panel is visible. I am trying to call an animation from a javascript function, but the animation doesn't work, everything else does.
I looked up the threads about this. But I couldn't do it...
this is my method in aspx.page:
public void MesajlariGetir() { DataSet ds = new DataSet(); SqlConnection con = new SqlConnection(); SqlCommand cmd = new SqlCommand("msjlarigetir", con);
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();..........................

1) here I want to call 2nd Execute method inside 1st Execute method.

In the content page, I have an ajax accordion pane with couple of panes. Within each of those panes there is 1 user control. Initially all the panes except the first one (AccordionPaneMain) is enabled. The first pane user control contains a form view . In formview itemcommand I am doing some processing and then was trying to enable rest of the panes by calling the function showPanes in the main page by using invoker method. My problem is, the method (showPanes) is getting executed but the panes are not enabled.
I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
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.
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I am new to ASP and ASP.net.I have just started working on a legacy ASP classic project and been given a sample that makes a remote call in ASP.net.Is it possible to call the ASP.net page from ASP?Are you they compatible.My impression so far is that they aren't compatible, but perhaps. I'm wrong.I mean the .net project could be called with parameters and kept seperate I guess?Does anyone have any experience with similar problems or have any tips they can share?
I've a method associated with an actionlink in the asp.net mvc view. When user clicks on actionlink the method is being called twice before the user is redirected to an appropriate page. Following is the code.
I have 2 text boxes inside my aspx page and I want to call the same method func(object sender, EvenArgs ev) on ontextchanged events of these textboxes.I want to parse the text of these textboxes inside this function - now the question is how would func(object sender, EvenArgs ev) know which of the textbox's has called it? I need to know that so that I could then use text property of that textbox to parse it and further process it.Isn't there a thing like sender.equals(textbox1).Or probably is there a way I could pass the text as a string argument to func()? If yes, how and whats the format?I dont want to make two functions separately for ontextchanged events of these textboxes, when the fucntionality of this method remains exactly the same.
I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.
I am working on an add-on component that needs to play nice with other similar add-ons. There is a 3rd party component that decided to implement the functionality a little differently than the default. What I am trying to do is call an overload of a method that only the 3rd party component has, like this:
Select Case True Case TypeOf provider Is 3rdParty.Provider result = DirectCast(provider, 3rdParty.Provider).GetNames(method, True) Case Else result = provider.GetNames(method) End Select
Unfortunately, the DLL that contains 3rdParty.Provider is optional, so this code will give compile errors if it is not present. How can I accomplish the same thing but make it safe to run whether the 3rdParty.Provider.dll is present or not?
