End Function

End Class

can any one help me , why this is not work ,

hi ikrima,

Add the following attribute above your webservice class

[ScriptService]

Regards,

Replace this"<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _"line of yours with -----> <ScriptService()> _

Thanks for our replies

i replace my code and change it to <scriptservice()>_ but till now it does not work , and when try to trace my code i found that the autocompleteExtender does not call the webservice , when ever all other ajaxtoolkit is running well

so what is your suggession to solve this ?

HI Ikrima,

Why do you set the propertyautocomplete="off"> ??

Regards,

HI ,

if you rfer to the samplewebsite which is download with AjaxcontrolToolkit source , you will find in the Autocomplete sample they use it ,

actually i try to remove it also but nothing happend

Thanks

Move your MESCService.asmx to your ScriptManager

e.g.

<asp:ScriptManager runat="server" ID="ScriptManager1" EnablePartialRendering="true">
<services>
<asp:servicereference path="~/MESCService.asmx" />
</services>
</asp:ScriptManager>

Hope it works. For it works. For me it does.

, still not working................

Even there is no query on server or any response/request from the page it just ignore it

hi i have the same problem in c#,so if u find any solution,please post it here

thanx

replace "<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _" with "<System.Web.Script.Services.ScriptService()> _"

Have you found a solution to your problem?

I found the solution, it seems that the Function name DOES matter. Here is my webservice code returning a generic string array:

strArray(0) =

strArray(1) =

strArray(2) =

Urgent: AutoCompleteExtender doesnt work/Updatepanel doesnt work

This is my code for the AutoCompleteExtender

<asp:textboxid="txtQuickSearch"runat="server"CssClass="inputText"style="width:145px; "></asp:textbox>

<atlas:AutoCompleteExtenderrunat="server"ID="acSearch">

<atlas:AutoCompletePropertiesTargetControlID="txtQuickSearch"Enabled="True"ServicePath="http://localhost/Sony.BusinessSuite.Web.UI/AtlasServices/MasterData.asmx"ServiceMethod="GetAllModels"minimumprefixlength="2"/></atlas:AutoCompleteExtender>

When i start typing fiddler shows:

#ResultHostURLBodyCachingContent-TypeUser-defined1401localhost

/Sony.BusinessSuite.Web.UI/AtlasServices/MasterData.asmx?mn=GetAllModels

4.431text/html

The same happens with an update panel...

basically i've been trying to use atlas things in the application we are working on here for about 3 weeks now... and up until now it has been very cumbersome and time consuming.

Hi,

Could you post the code for the method you are using in your webservice

Thanks

Hi,

you are getting a 401. I believe that it happens because you are trying to access a web service in another domain and this is not allowed in normal conditions. Please checkthis thread.

Here's the webservice code, thanks in advance to have a look...

[WebService(Namespace ="http://tempuri.org/")]

[WebServiceBinding(ConformsTo =WsiProfiles.BasicProfile1_1)]

[ToolboxItem(false)]

publicclassMasterdata :WebService

{

[WebMethod]

publicstring[] GetAllModels(string prefixText,int count)

{

ArrayList filteredList =newArrayList();

//Get the available product categories from the principal object.

Principal principal = (Principal)Context.User;

List<Category> myCategories = principal.Categories;

List<DKCategory> myDKCategories =newList<DKCategory>();

foreach (Category catin myCategories)

myDKCategories.Add(newDKCategory(cat.OID));

//Get the models from the masterdata service (limited to the users available categories).

Proxy.Pricing.Model.ModelService ModelSVC =new Proxy.Pricing.Model.ModelService();

List<Model> myModelsSVC = ModelSVC.GetModels(myDKCategories,null);

foreach (Model modin myModelsSVC)

{

if (mod.Name.ToLower().StartsWith(prefixText.ToLower()))

filteredList.Add(mod.Name);

}

return (string[])filteredList.ToArray(typeof(string));

}

}

Hi,

I tried the solution in the thread you suggested, but it didn't work. I don't think it is related to this though, because the webservice i'm calling is in the same project than the page consuming it.

Could the problem be related to the fact i'm using the "web application project"? or nested masterpages?

Wesley

hello.

what response do you get from fiddler?

Hi,

Have you tried using as RelativePath within your ServicePath parameter?

Regards
