AJAX :: Calling Javascript After Web Method Has Fired?
Jul 22, 2010
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 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 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 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 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'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 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.
but I am getting this error
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 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);
function LogInUser() { var LoginName = document.getElementById("<%=txt_LoginName.ClientId %>").value; var Password = document.getElementById("<%=txt_Password.ClientId%>").value;
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 want to call a javascript method during page load. I am using application.master of the sharepoint server 2007 as the master page . In the content page i want to call a custom method named OnLoadFun() during loading the content page. I have written the function inside script tag in the PlaceHolderAdditionalPageHead id section of the content page.
[Code]....
How do i call the OnLoadFun method so the i is being called onload time. i tried putting window.onload=OnLoadFun surrounded by script tag within the PlaceHolderMain content section.
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 had a standard ASP.NET page where I had a some client side Java script make some controls visible/enabled if a checkbox was clicked or not.
[Code]....
Now I would like to move this same WebForm functionality into a AJAX Control Kit TabControlPanel
[Code]....
Here is what I have tried, but it won't compile. I get the following error. Where do I put the script and how do I reference controls in the AJAX TabControlContainer?
Error 10 'ASP.default_aspx' does not contain a definition for 'Email2Checkbox' and no extension method 'Email2Checkbox' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?) C:InetpubwwwRootAjaxTestSiteDefault.aspx 458
I've tried a bunch of different examples and still can't get this to work. I have a jQuery GalleryView control I'm using and I simply want to log impressions. I set up a webservice that works, but I can't figure out how to get it to work in javascript. I have verified that the webservice is working as expected.
I have a page that calls a webservice from JavaScript using the approach described in this article: [URL]
This is working fine. The problem is when the page causes a postback before the end of the execution of the webservice's method. When that happens, the succeeded callback method never gets called. Does anyone know if there's a workaround to this?
So I have this idea of creating a asp.net user control, to handle all forms of modal popups (whether it be error handling, forms, dialogs, etc).
I already created this before, placing the user control in the top master page, exposing it to all content pages, so I could do something like:
Master.Popup.ShowException(Exception);
And the usercontrol itself would have the necessary markup to look like a modal dialog, and in the show method just do a .Visible = true.
This is all fine, but I've started thinking of implementing a bit of style with jquery. I'd like for the usercontrol to have some sort of jquery animation on show. But I don't know how to go about achieving this, as I don't know how I would call that jquery function from the codebehind instead of the popup.visible = true.
