I have defined a web service function for AutoCompleteExtender, but in addition to the two parameters passed "prefixText" and "count" i want to pass another parameter for a label in that function. So, how to define that ?

it is possible that AutoCompleteExtender can call a service Web of another project of my solution?
View 1 RepliesI am successful in using the AutoCompleteExtender control by make use of web serivces as the data source (ServiceMethod) to the extender control. My question is do we have any way in assining a code behind method as data source to this control.
removing the ServicePath url and assiging code behind method to ServiceMethod attribute will resolve the issue.
I tried your code for Autocomplete without Webservice and didn't work on my page. When I tried it on a new project it works fine but on my project it does not. I have other controls on the page but that shouldn't stop it from working right?
Attached is my code
<%@ Page Title="" Language="VB" MasterPageFile="~/intranet.master" AutoEventWireup="false" CodeFile="warehouse.aspx.vb" Inherits="warehouse" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

I have created an autoextender & cannot seem to get it to work within my pages. So I'm missing something probably small yet important.
The webservice AutoComplete.asmx, when called by itself, does return data correctly.
The codebehind for AutoComplete.asmx is located in the App_Code folder.
AutoComplete.asmx and the page from which I am calling it are both located in the root folder.

But image never is changed. So I think something wrong with ChangeImage().
How do I run a function associated with my custom control after it is initialized? So for example, after the control has initialized (ie is loaded) I need to finalize some properties. But since it is composed of a number of other controls, I need to know all the controls are present. I've tried add_load but I can't seem to get the context right to see my contol's specific functions. If I place the onLoad metod in the main class (javascript) definition, the contol id dosen't exist yet, same for in the prototype.
Since the control id dosen't exist yet I need to wait for the load event but now i'm in a chicken and egg problem. How do I create a method of my control class and call it "after" initilization? Seems like a simple question but it hasn't been so easy to find an answer.
Scenario : I am going to access external web service [ExternalWS] using AJAX. So obviously, need to create local proxy service [LocalProxyWS] first, which in turn will access the external web service. Now, the external service webmethod [Process] basically redirects the current page on our site to their site, does some work and then return back to our site.
What I want : I want that when the user clicks the button ('Process') on our site, it should open a new window and then starts executing the request on the new window, so that I can have the page on my website to be displayed permanently (which will poll a request every 15 seconds to the external service (via local proxy) for the status).
Local Proxy service which calls external service is as follows..
[ServiceContract(Namespace = "LocalProxy")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class LocalProxyToExternalService
{
[OperationContract]
public void InitiateTransaction(string amount)
Basically, I am opening a new window from the button click and then want to process the new request in that new window, so that I can show the status to the user from the current page on my website So far, it opens the new window, but doesn't transfer the request on to that, but I get an error message in firebug as follows...
I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.
Once i push the button to execute the JS/AJAX/codebehind - I got an error.
POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)
This is my code below that I am currently using:
Code:
<WebMethod> _
Public Shared Function getDBInformation() As String
loadDBData()
Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented)
End Function
End Class
The code behind looks like this:
Code:
Imports System.DirectoryServices
Imports System.Security.Principal
Imports System.Net
Imports System.Drawing
Imports System.IO
Imports System.Data.SqlClient
Imports System.Web.Services
Imports Newtonsoft.Json
[Code] ......
How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?
I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file):

Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:ProjectsSamplesmytestwebsite'".
I have designded a asp.net server control that have an embeded javascript file.
document.getElementById("div_Messages_Back").style.left = 0;
document.getElementById("div_Messages_Back").style.top = 0;
document.getElementById("div_Messages_Back").style.width = document.documentElement.clientWidth;
document.getElementById("div_Messages_Back").style.height = document.documentElement.clientHeight;
document.getElementById("tbl_Messages").style.left = (document.documentElement.clientWidth - 250) / 2;
document.getElementById("tbl_Messages").style.top = (document.documentElement.clientHeight - 120) / 2;
function btn_Close() {
document.getElementById("div_Messages_Back").style.visibility = "collapse";
document.getElementById("tbl_Messages").style.visibility = "collapse";
}
I want the first 6 line of my javascript file run at runtime. But I recieve error at runtime:
Error: Object Required.
I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this
MyControl myControl=(MyControl)userControl;
The reason i need to do this is because my user control has a custom property, person, I need to do the following:
myControl.Person=new Person();
essentially i need to simulate:
<%@ Reference Control="~/UserControls/MyControl.ascx" %>
which normally goes inside asp.net page or master-pages.any way of doing this in an Ajax Enabled WCF Service?

i'm using visual web developer 2008 express edition, i added the ajax toolkit to the tools without issue. SOME tools, like the accordian (and others) allow me to drag and drop them onto my forms. but others, such as the autocompleteextender wil not allow me to drag and drop them onto a form. i just get a circle with a line through it (as if to say - this is not allowed) - why is that?
i tried coding the extender in manually like many examples i've seen online:
<cc1:AutoCompleteExtender TargetControlID="txtName" ServiceMethod="GetCustomers" ServicePath="AjaxService.asmx"
MinimumPrefixLength="1" ID="AutoCompleteExtender1" runat="server">
</cc1:AutoCompleteExtender>
but it underlines "cc1" and gives me the error: "unrecognized tag prefix"
what am i doing wrong?
I've got an AutoCompleteExtender on one of my pages, it seems to be working fine aside from this strange behaviour: Let's say I key in 2 characters, the suggestion list would display. When I press on backspace to delete those 2 characters, wait until the suggestion list to disappear, and re-enter those 2 characters, the suggestion list would no longer display (or sometimes would flicker for about a second after losing focus from the textbox) and I'll need to refresh the page just to get it working again.
However, if I do press backspace and delete those 2 characters but not let the suggestion list to disappear and re-enter new characters, it would continue displaying with correct suggestions. This behaviour seems to happen only in IE8, (although it works with IE8 using Compatibility View and Firefox)... My code is almost the same as the sample on this site except for the animations, and the service looks up in a database table.
