AJAX :: AutoComplete Extender Using A Page Method?

i have developed a AutoComplete Search with the JAX AutoCompleteExtender Now i found a solution to use these control without a webservice (amsx) you only have the function in the codebehind (default.aspx.cs) , to do this you must let theServicePath empty. In the codebehind of your webpage is only the function which gets the data from the database.Important the function must be static !!

AJAX :: Calling A Web Service From Extender

Apr 8, 2010

VS2008
Using C#
AJAX Toolkit 20229.20185

I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.


Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error
Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]

AJAX :: Autocomplete / Can't Get It To Hit The Method In My Service With A Signature?

Apr 9, 2010

I have a web control with a text box configured like this:

[Code]....

I am unable to get it to hit the method in my service with a signature like:

public
string[] GetOrganizationNames(string searchText,
int count)

but it does get to the method if I change the signature to:

public
string[] GetOrganizationNames()

For obvious reasons the second one will not do me any good. I have verified the data coming back from the method is good.

JQuery :: Autocomplete Call WCF Service Method

Oct 20, 2010

I am trying to use the below code to call a wcf service method for Autocomplete functionality in a TextBox. I have written the following query:

$(document).ready(function () {
$("#<%= txtCompany.ClientID %>").autocomplete [URL], {
dataType: 'json',
parse: function (data) {
var items = data.d;
var parsed = [];
for (var i = 0; i < items.length; i++)
parsed[i] = {
data: [items[i]],
value: items[i],
result: [items[i]]
};
return parsed;
}
});
});

The same query works if I pass a Java Script array variable instead of the wcf service method. The wcf service method contract is:

[OperationContract]
[WebInvoke(Method = "GET", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json)]
string[] GetTestCompanyList(string prefixText, int count);

Calling Linq To SQL Method In Web Service With JQuery?

Jan 24, 2010

I have a test web service called: MySimpleService.svc with a method called:GetUserNamesByInitials. below is the Linq to SQL code:

[OperationContract]
public static string GetUserNamesByInitials(string initials)
{
string result = ""; [code]...

what I do is to type the user id in one textbox (TextBox3) and when I press the Tab key the result is shown in another textbox(TextBox4).
The jQuery call works well with other methods that do not call the database, for example using this other web service method it works:

[OperationContract] public string ParameterizedConnectionTest(string word)
{
return string.Format("You entered the word: {0}", word);
}

However with the Linq method it just does not work.

AJAX :: AutoComplete Extender Seen Only After One Tab?

Jun 7, 2010

I am using AJAX Control toolkit V-1.0.

I am coming across one problem with auto complete extender in my application, problem seems to simple but i can't find any satisfactory solution. In one form, i have set auto complete extender on one text box, i have set one web service, in which one function is there, which fetches existing records from db, on first load, if i write releavent words with that of db, i can't see the extender, but if once either i minimize the page or give tab despite AutoPostBack property of text box is false, then after writing something in text box shows me the extender.

Here are the properties of both text box and extender

<asp:TextBox
ID="txtCompanyName"
runat="server"
CssClass="txt"
MaxLength="100"
TabIndex="4"
Width="443px"
></asp:TextBox>.........
