I have a textbox with the autocompleteextender in VS2010 that is referencing a webservice. However, nothing I seem to do makes this work as no values are returned when I begin typing in the textbox. When I view the webservice in my browser and invoke it, it returns values so I know that my webservice works. Code below.
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
<asp:TextBox ID="Task1" runat="server" CssClass="CENTER" Width="160px"></asp:TextBox>

I ultimately need to show countries in one drop down then states/provinces drop down of the previously selected drop down. I'm sure everyone has seen this many times. My page shows the countries but does not show values in the province/states drop down. It's as if the webservice is never run. I've tried removing and adding the ajaxtoolkit reference. The tableadaters run simple working sql code. I'm really at a lose here.

What should I try to clear this up?
i have declared an int variable; something like that:
int ret = ws.GetVersion();
the webservice correctly load the value and return to the client, however in the client if i select ret and hit shift+f9 it say that ret doesnt exist in that context.but if that would be the case i would get a compiler error,
I have a web service file in my project having a web method which is used for AutoCompleteExtender and which works fine when I debug it from VS. But when I publish and host it on IIS, it's not working properly. However, I tested the webservice method directly by typing the URL and it gave the desired output. Is their a special setting needs to be done in IIS to make it working or any property of AutoCompleteExtender need to be set?
View 3 RepliesI have this code:
$('#' + textboxID).autocomplete({ delay: delay, source: ["cats", "dogs"] });
which works fine.
I want to use a webservice:
$('#' + textboxID).autocomplete({ delay: delay, source: webserviceURL});
This doesn't work. My webservice URL is /blah/blah.asmx/myMethod
The webservice definition is:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<string> myMethod(string term)
{
// Logic here, return list of strings
}
The method never gets called. Can anyone point me in the right direction? I have other webservices in the same .asmx which work fine with other controls (other controls are using $.ajax to call them).
Edit: Getting closer, I now get a 500 error saying Request format is unrecognized for URL unexpectedly ending in '/myMethod'. I think it's not treating my url quite right..

And trying to access webservice using javascript in my subdomain, but its not working in FF, working fine in IE. I have also tried using crossdomain.xml file which too works fine in IE, but not in FF.
I have a simple page that looks up contacts using a webservice with a single method written in Linq. On the page, I have both a gridview and a listview with a DataPager to compare the two. I can get paging working just fine with the gridview, but the Linq code has to return all of the data on each call and let the web page pick out only a page's worth... not the best solution. I have been told that a ListView will solve this problem, but all the examples I have been able to find have the Linq code on the web page instead of in a separate layer (e.g. a webservice). Ideally, I should be able to tell the web service to bring back a specific page worth of data (starting record number and number of rows), but how do I get the ListView (or the DataPager) to fire an event that asks for this data?
Here is the ASPX code:
<asp:ListView ID="listPersons" runat="server"> <LayoutTemplate>
<table> <thread> <tr> <th> Site ID </th> <th> PersonID </th>
<th> Person Name </th> </thead> <tbody>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" /> </tbody> </table>
<asp:DataPager ID="Pager1" runat="server" PagedControlID="listPersons" PageSize="5" > <Fields>
<asp:NextPreviousPagerField ShowFirstPageButton="true" ShowPreviousPageButton="true" ShowNextPageButton="false" ShowLastPageButton="false" /> <asp:NumericPagerField />
<asp:NextPreviousPagerField ShowFirstPageButton="false" ShowPreviousPageButton="false" ShowNextPageButton="true" ShowLastPageButton="true" />
</Fields> </asp:DataPager> </LayoutTemplate> <ItemTemplate><tr> <td> <%# Eval("SiteID") %>
</td> <td> <%# Eval("PersonID") %> </td> <td> <%# Eval("PersonName") %> </td>
</tr> </ItemTemplate> <EmptyDataTemplate> No data found... </EmptyDataTemplate> </asp:ListView>
Here's the code behind:
private void DoList(string Match) {
ContactsService cs = new ContactsService();
listPersons.DataSource = cs.Find(Match, 100 ); listPersons.DataBind(); }
and the web serivice:
[WebMethod]
public List<Person>Find(string Match, int Count) { if (Count < 5) Count = 5;
using (DataLayer.ContactsDataContext context = new ContactsDataContext()) {
var Persons = from p in context.Persons where p.PersonName.Contains(Match)
orderby p.LastName, p.FirstName select new Person() {
SiteID = p.SiteID, PersonID = p.PersonID, PersonName = p.PersonName, };
return Persons.Take(Count).ToList(); } }

I am new to ASP.NET (2 months) and my very first assignment is to create a website for a municipality. Purchasing as much reading material as possible, I got started and after some time, I have a decent website (coded in C#) that is ready to be internally tested on the departmental webserver. The Web server is running IIS 7 and the pages were developed with Visual Studio 2010. On the main default page, I wanted to implement a slide show using the AJAXControlToolkit which I installed. I watched the ASP.net tutorial [URL] and literally coded my slide show verbatim. I try to launch my slideshow within my default.aspx page and absolutely nothing happens. The steps that I took are
1. Created a webservice (SlidesService.asmx) which generated a code behind file (SlidesService.cs).
2. I created the web method GetSlides() containing a 22 element array which I place in the code behind file.
3. Implement the ToolkitScriptManager establishing my image control.
4. Defined my Previous, Play and Next buttons.
5. Implemented my SlideShowExtender providing my SlideShowServicePath and SlideShowServiceMethod.
Assumptions: In doing all of the above, I noticed that the SlidesService.asmx file needs no code (as I placed all code within the codebehind file). The SlidesService.cs code behind file should reside in the App_Code folder whereas the the SlidesService.asmx file can remain in the root folder. No Button e.g Button_Click needs to be attached to the code behind source file. If I have conveyed my steps properly, can anyone shed some light on why when clicking the play button, nothing happens? Code is listed below.

SlidesService.asmx - code

Can I Use CascadingDropDown without WebService?
View 1 RepliesI am planning to use a Javascript call to a WebService to retrieve data from the database. At the moment I am using Ajax to do this. But since the Ajax is slowing down the performance of my application. I have read in some article that even though Ajax only refreshes the Update panel contents, Ajax does a full round trip to the server. What I need to know is how can I populate a Grid from data coming from a WebService via a Javascript call.
View 3 RepliesAfter the implementation of ajax drag and drop, we have observed that which is working fine in IE and Firefox and not in chrome and safari, In Google chrome and Safari when we try to drag a module, the page getting scrolling to the top of the page.
View 1 Repliesi have application with 2 cascading dropdownlists that got populated using web service, when a value was picked in the first one the second filled with values, now when the second one got selected i want to poulate listview with images links.
View 2 RepliesI am working on an application just like any fast food restaurant uses for example McDonalds.
Basically, application consists of three parts.
1) Web Application # 1 to take orders (Used by the clerk(s))
2) Web Application # 2 to process orders (used by the chef back in the kitchen)
3) WebService returns new orders (with PENDING status) to Web Application # 2.
Write now, Application # 1 adds new orders to the database. Application # 2 calls the WebService to get new ordes by REFRESSHING the page again and again. Refreshing the page over and over again is the problem.
I want the WebService to automatically send new data (oredrs with PENDING status) to Web Application # 2 whenever Application #1 add new order.
Application # 1 can call WebService (sending true flag) to let it konw that something has been added so the WebService can broadcast new date to Application # 2
Here is the flow which I am trying to achieve
Application # 1 (Takes new Order)
Application # 1 then call WebService (sending true)
WebService (if true is received), send new data to WebApplication # 2, cause postback on Applicatin # 2 automatically
For Example just imagine when you walk in McDonalds
Clerk takes your order -> New order is automatically send to the Kitchen (to process order)
Here is the breakdown
Application # 1 = Clerk taking order
WebService = Mechanism which is sending new order to Kitchen
Application # 2 = Monitor in the Kitchen receiving orders.
Iam new to webservices,Till now I did not use web service.Anybody can you give a real time example for webservice.Please it will be very useful for me.
View 3 RepliesThis has totally spoiled my .net 4 vs2010 realease day happiness. Running Cascading dropdowns using 'webservice' asmx method. Everything worked on .3.5 and i solved the running 'code In page' method with this post. Method error 500 [URL] Thought I was sorted but seems the rules are totaly different for the 'webservice method'. For example where did ToolkitScriptManager come from Ive been using ScriptManager for years. Anyway below is the Webservice and Page code. Ive looked at and tried everything of the forum but all of it is pre .4. This is demo code, the real version has 3 dependant dropdowns and the lookups are used several times so it HAS to be a webservice. My current theroies are:
1. Permissions- dosent makes sense.
2. Something missing in web.config to enable webservices.
3. Something to do with placement of 'System.Web.Script.Services.ScriptService()>'
