EDIT: Sorry forgot to mention what i was using.... I installed VS Web 2008 Express, so i am trying to use it in ASP.NET,... also, the instructions that i have seen say to use the ASP.NET Ajax, i am going to look at the video again., that does a step by step,.
and see if i did something wrong.
I finally got the AJAX controlbox to show,
After i add the extender and try to add the page method i get the exception
Exception has been thrown by the target of an invocation
how do i make sure that the control kit is correctly installed??? i have installed the 3.5 ext, and downloaded the kit., when i try to launch the AjaxControlToolkit.sln Web VS 2008 gives me a
"The projects componenets are not installed on this computer. Please re-install Visual Studio"
i download the latest AjaxControlToolkit-Framework3.5
in the readme it says
"Welcome to the ASP.NET AJAX Control Toolkit!
Included in this package:
* AjaxControlToolkit - A set of sample ASP.NET AJAX controls and source
* SampleWebsite - A web site that demonstrates how to use the controls and
contains the rest of the Toolkit documentation
* ToolkitTests - A web site that contains automated tests for all controls
* AjaxControlExtender - A VSI installer that will install templates onto your
machine to enable creation of new ASP.NET AJAX extender controls using
Visual Studio 2005
To get started, simply load the "AjaxControlToolkit.sln" solution in Visual
Studio 2005, and run the solution. This will launch the web site and allow
you to experiment with the different controls. Also included in the solution
is the source code for all the controls.
The web site also contains walkthroughs covering:
* Setting up your machine to use control extenders
* Using control extenders with your ASP.NET web site
* Creating new control extenders
* Writing your own automated tests
Version 3.0.11119.0
2007-11-19 release of the AJAX Control Toolkit targets the official release of .NET Framework 3.5 and Visual Studio 2008.
AjaxControlToolkit-Framework3.5.zip is the full release package with complete source code to all controls, the test framework, VSI, and more.
AjaxControlToolkit-Framework3.5-NoSource.zip contains only the sample web site and VSI and is for people who don't need or want the source code for the controls.
I have VS 2005 Pro, I Installed the Ajax Tooklit and the 2005 SDK.
The Sample project opens, loads and runs normally, but when I put an Autocomplete on my form and Right-Click - Add Form Methods. It trys to add code then pops.
I look in the Code behind and see a messed up function:
Public Function GetCompletionList() As System.String[]
End Function
Looks like a mix of VB and C#
What code is supposed to be added so I can continue?
<System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()> _
Public Shared Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String()
' you can create a custom string array and return it
Dim r As String() = {"aaa", "bbb", "ccc"}
Return r
End Function
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey)
{
// you can create a custom string array and return it
string[] r = {"aaa", "bbb", "ccc"};
return r;
}
perfect., since you are looking at ajax.net you might run into dynamiclly adding controls and order matters in that so you might want to look at
http://forums.asp.net/p/1142457/2191394.aspx#2191394 just incase
lets try baby steps., this code if from my proof of concept... it was specifically written to do something so i have had to strip some stuff out, you know how fancy dynamic code gets., i think i also have some commented out code in my app that i might have
used to start building my dynamic content., try the following..
Dim manager As ScriptManager =
New ScriptManager
form1.Controls.Add(manager)
Dim APanelControl
As Control
Dim aAccord As AccordionDim accordPane
As AccordionPane
'' ADD some DATA
aAccord =
New Accordion
Dim AccordianLoopHolder as integer = 1 ' in this case.. my code is dynamically creating by loops., so lets just make this ., 1
oh i do understand that you are not using accordians :) i wasnt sure how much you had explored on the ajax.net i believe i have an autocomplete piece that i did also., somewhere., the issue is that most of my prrof of concepts become
website1...... websiteN :)
so right now im gotomypc'd into my laptop which has the code.... ill be headed back home in a bit, when i am infront of it i could try to get you what you are looking for?
found it., this one doesnt use dynamic code to create the textbox+autocomplete but... it has a static textbox with autocomplete., this works, you shd be able to figure out dynamic build up with this., or when i get home i can help you by looking for my dynamic
code..
now to attach the file somewhere for you to download
k., here is the piece that does the autocomplete., it might solve your issue as it will overcome the vs bug., its simple, might be too simple for you., but like i said i dont mind helping you build this into what you want
The file webresource.axd does not exist, I don't know if that is a .Net thing though.
I looked at the source of the ASP.NET Sample and they have the same sys.Application, they dont have sys defined anywhere but IE has no errors for their sample.
I can't find what is different between the sample and mine.
You could try not using a web control just to see if it works? And then backtrack to getting it working in a control?But
I do not think its mainly because of that,
Ok, i tore out everything but the 5 files involved
I put the rar file on a free website:
http://dryrtf.freewebspace.com/
I downloaded The Ajax Control Toolkit Web Site and it completely works
I have a VS 2005 Pro website that I am trying to add the Autocomplete to.
I have added Ajax to the Tool bar in VS, I can drag n drop items onto a page and see the components.
That tiny sample shows the error (yellow exclaim in bottom left status bar area of ie)

also check in the web.config for the samples that work if there is a <httpHandlers> tag,,,, if there is try to place that in your web.config....
looked at your project., initially it didnt work., i need to run for dinner., but., what i did was i moved your function call for the list to the defaults code behind
Public Shared
Function GetCompletionList(ByVal prefixText
As String,
ByVal count As
Integer, ByVal contextKey
As String)
As String()
' you can create a custom string array and return it
Dim r
As String() = {"Prolax",
"Profin", "Prodex"}
Return r
End Function
and it worked., i think because u are registering the getcompletionlist in the usercontrol it wont/cant fire it up., its possible that to fire it up you might need to use

The rabbit hole you just sent me down has made me remove all html of the autocomplete and try to add code on page load to do it all.
(I prefer code to html)
So in my page load:
If IsPostBack = False Then Dim ats As New AjaxControlToolkit.ToolkitScriptManager ats.EnablePageMethods = True ats.EnablePartialRendering = True ats.EnableScriptGlobalization = True ats.EnableScriptLocalization = True ats.EnableTheming = False ats.EnableViewState = True Dim atc As New AjaxControlToolkit.AutoCompleteExtender atc.ID = "atc" atc.TargetControlID = AutoCompleteBox.ID atc.ServiceMethod = "GetCompletionList" atc.MinimumPrefixLength = 2 atc.CompletionSetCount = 20 atc.CompletionInterval = 1000 atc.CompletionListCssClass = "autocomplete_completionListElement" atc.CompletionListItemCssClass = "autocomplete_listItem" atc.CompletionListHighlightedItemCssClass = "autocomplete_highlightedListItem" Me.Controls.Add(ats) Me.Controls.Add(atc) End IfIt still doesn't work, but there is a Javascript error on the page:
Error: 'Sys' is undefined.
I viewed Source and see:
The first part is my treeview, the Sys is the Ajax generation.
my hole seems to have cave'd in
Any Ideas?

I'm not using Accordians, Just trying to help user spell things from the database in a Drug Name text box.

Thanks,
I think my problem might be from the multiple levels going on here.
My site has a Master Page (which is where I put the form since you can only have one)
Then the Page,
Than a Web user control that has the Textbox I am trying to make an autocomplete
The user control has more than one textbox, (Drug name, Strength, Pills per dose, and so on)
I have a few pages that needs the same information, that's why I put them in a user control.
Trying to make the user control handle it's own AutoComplete for only one of the Textboxes is where I'm at.

I made sure I was setting all the properties in your sample, and the ASP.NET Sample.
Still getting sys is not defined.
Looking in the ViewSource i see :
The file webresource.axd does not exist, I don't know if that is a .Net thing though.
I looked at the source of the ASP.NET Sample and they have the same sys.Application, they dont have sys defined anywhere but IE has no errors for their sample.

No there were too many errors in Web.Config
There's no file I hate more than Web.Config.
But I copyed the settings you used, do you think it is because i'm in a web usercontrol

you have an ASP.NET web site, that you are trying to ajax enable
Or

try this
under
<assemblies>
put 1 more in there the version should be right., you could compare that line with the samples web.config line (that work)... to ensure the token/versioning...
<add assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
also check in the web.config for the samples that work if there is a <httpHandlers> tag,,,, if there is try to place that in your web.config....
<add verb="GET" path="ScriptResource.axd" type="Microsoft.Web.Handlers.ScriptResourceHandler" validate="false"/>
if you want., you could show me the web.config for the one that works and i can tell you where to copy paste., or put it together for you :)

I added the httphandlers and the sys error finally went away but the dropdown is still not showing.
Did you look at the Project? on the free site?
Here's the web.config from the AjaxSampleSite that works:

Re: Add Autocomplete page method throws a Exception has been thrown by the target of an invocatio...
May 29, 2008 08:41 PM|zeeomar|LINK
looked at your project., initially it didnt work., i need to run for dinner., but., what i did was i moved your function call for the list to the defaults code behind
<System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()> _
Public Shared Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() ' you can create a custom string array and return it Dim r As String() = {"Prolax", "Profin", "Prodex"} Return r End Functionand it worked., i think because u are registering the getcompletionlist in the usercontrol it wont/cant fire it up., its possible that to fire it up you might need to use
xyzusercontrol.GetCompletionList
i can mess with it when i get back.,
