AutoCompleteExtender properties : CompletionInterval, CompletionListElementID, CompletionSetCount

Since ASP.NET AJAX 1.0 and I cannot find any documentation on the AutoCompleteExtender properties such as :

- CompletionInterval

- CompletionListElementID 

- CompletionSetCount

Please I would like to know what those properties do and how to use them !

If you google "CompletionListElementID", you'll get only 5 results, most of them are not very helpful.

I only found a tiny example (http://forums.asp.net/3/1458343/ShowThread.aspx) on how to format the list popping below the textbox using CompletionListElementID and a div but it seems like you can only reach the font-family and the font-size (neither the color nor the background-color for instance).

The dev team throws controls out there with no documentation and you're supposed to figure out on your own how they work ?!... 

Need help, ASP.NET AJAX, AjaxControlToolkit


Hi, please forgive me if this question already answered before. I need help urgently.

I'm developing a web application (not website) which can be created under "New->Project->ASP.NET Web Application". I'm using Visual Studio 2010.

My problem is, all AJAX working fine except for the AjaxControlToolkit. I try to include the ValidatorCalloutExtender and it failed to work as in it won't display. However I created same thing using "New->Website->ASP.NET Website" instead and it works.

Question: Is AjaxControlToolkit only work on website but not web application? Is there anyway to use it on web application?

ModelBinders obsolete in MVC2?



I have a shopping cart that uses MVC 1 (guide from the book "Pro ASP.NET MVC Framework" by Steve Sanderson). Now that MVC 2 and VS2010 are released, the shopping cart no longer works.

Is there any changes about the ModelBinders.Binders.Add(), is it obsolete in MVC2? The code binder below wasn't hit at all in Application_Start(). Sad


    Sub Application_Start()

ModelBinders.Binders.Add(GetType(ShoppingCart.Model.Cart), New CartModelBinder)
End Sub


Imports System.Web.Mvc

Public Class CartModelBinder
Implements System.Web.Mvc.IModelBinder

Private Const cartSessionKey As String = "_cart"

Public Function BindModel(ByVal controllerContext As ControllerContext, ByVal bindingContext As ModelBindingContext) As Object Implements IModelBinder.BindModel
If (Not (bindingContext.Model) Is Nothing) Then
Throw New InvalidOperationException("Cannot update instances")
End If
Dim cart As ShoppingCart.Model.Cart = CType(controller

AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. - Error being thrown while building asp.net si


Everytime I build my site in VS2010 Beta I recieve a few ajax errors before the site loads here they are in order as they pop out on the build; 


throw new Error("AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the AjaxScriptManager in System.Web.Ajax.dll, or use the ToolkitScriptManager in AjaxControlToolkit.dll.");


And then Next this line is throwing an error, I have a watermark ajax field on the page that I created a long while ago;

Sys.registerComponent(Sys.Extended.UI.TextBoxWatermarkBehavior, { name: "watermark", parameters: [{name:"WatermarkText",type:"String"}, {name:"WatermarkCssClass",type:"String"}] });

 And then lastly;

 if (Sys.Extended.UI.TextBoxWrapper.get_Wrapper(this.get_element()).get_IsWatermarked())

AjaxControlToolkit.HTMLEditor adding H1,H2,H3


I like to use the ajaxcontroltoolkit, but i'm missing the H1,H2,H3 possibilities.
How can i add it to the editor?

With a override class i can add some buttons, but how can i add the posibility to set <h1></h1> on the selected text?
And what if i change the H1 to H3...

I'll got stuck in this, i know how to add a button and javascript to it, but don't know how to add the H1 to it.
Also would a dropdownbox be better i think.
Can someone help me?

Coding to add a button:

                AjaxControlToolkit.HTMLEditor.ToolbarButton.MethodButton b = new AjaxControlToolkit.HTMLEditor.ToolbarButton.MethodButton();//= new AjaxControlToolkit.HTMLEditor.ToolbarButton.ImageButton();
                b.Visible = true;
                b.Attributes.Add("onclick", "javasciptcode");


contextKey in AutoCompleteExtender


How can I use the contextKey of an AutoCompleteExtender ? 

When I had a search, I got to know that using javascript we can fire the contextkey to the webservice. Could some one help me out in writing this script and how to use it in webservice ????

Using Ajax AutoCompleteExtender on dynamic fields



I have quite a problem with a form that contains an autocomplete function. The page is an aspx page with c# codebehind.

On the form there is an address field that the user can type in any string address. This field is using an Ajax autocomplete extender, which suggests roadnames to the user. This works fine.
Furthermore the user has the option to add multiple address fields when clicking a button. This works fine now with Jquery. Jquery copies the table which contains, besides other fields, the address field, and "paste" it underneath the existing adress field.

Problem is, how do I attach the Ajax autocomplete extender to the address fields that gets added? Or is there another workaround to make all these fields have this autocomplete function?

Here is my simplfied code:

aspx page:

<td width="200">
  <asp:TextBox ID="TextBoxStopRoadName" runat="server" Width="200"></asp:TextBox>
      <asp:AutoCompleteExtender runat="server"

Passing Textbox Value to ContextKey in AutoCompleteExtender



I'm trying to use the contextKey in the AJAX AutoComplete tool but there is a problem with regards to passing the contextKey value to the method located in the web service file.

Let me describe how my web form is organised.

There are two textboxes. One of them has the AutoComplete tool. The user enters a word in Textbox1 (which does not have the AutoComplete tool). Afterwards, when he clicks in TextBox2 (which has the AutoComplete tool) and starts to type, the AutoComplete tool will show him the close matches. Now, the items in the AutoComplete menu are retrieved from a SQL database. The Select command (of the AutoComplete which is in the web service file) returns values based on the the value of TextBox1 in the main forum.

This is the client-code of AutoComplete 1:

<cc1:AutoCompleteExtender ID="AutoCompleteExtender1"

I've been working on a project using MOSS 2007 for quite some time and I've been using the Collapsible panel extender successfully.  After installing the same assemblies on SP 2010 I've found an issue with what I think is the CollasiblePanelExtender.  I receive the following JavaScript error:

Invalid web service call, missing value for parameter: \u0027prefixo\u0027 (AutoCompleteExtender)


Good afternoon.

I'm trying to put an AutoCompleteExtender working, but i'm having an error, that i discovered with Fiddler, that is the reason that the autocomplete doesn't work:

Using tabs from the AjaxControlToolkit causes error: ...control contains code blocks (i.e. <% ... %>


I'm getting the error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

When attempting to add the tabs from the AjaxControlToolkit.  A little background..Theres an existing aspx page in a microsite which used the accordion control and the tabbed control ...I need to modify this page to use a different masterpage. 

The original site was .Net Framework 2.0 and the page in question used AjaxControlToolkit 1.0. which I manually installed originally.  Some of the site has been further developed using the .Net Framework 3.5.  (Come with AjaxControlToolkit) Now I have come to update this aspx page and I get the error above.

I have narrowed the down to the TabContainer (I think)  Does anyone have any experience with this sort of problem?  Also what version of the AjaxControlToolkit should be with the .Net Framework 3.5? I have 1.0.20229.20821. 

I also tried to browse to the AjaxControlToolkit.dll to add the tools to the tool box as they're missing... thinking this may be an indicator as to why it wasn't working. I get the error: 'There was an error loading types from assembly C:\inetpub\wwwroot\project\Bin\AjaxControlToolkit.dll Could not load file or assembly 'System.Web.Extensions. Version=

Ajax AutocompleteExtender not working from IIS


I am using  AjaxAutoCompleteExtender  in my asp.net program (C#) . I am applying the extender to a texbox and using internal Web Service. I am getting the desired result, when i am running from the development environment. After Publishing the site to IIS, I am not getting the list and not showing any errors. I have turned off custom errors. My website is not an Ajax Enabled WebSite. So i added the lines into my Web.Config.

I tried all service path.. http://localhost/Test/ WebService.asmx

and i tried ~/Test/WebService.aspx


While testing from the development environment, i am using the last one.

I am not sure whether this is the problem with the service path or any permission issue.

Ok, so this has been driving me mad for 2 days. I have a AjaxControlToolkit.HTMLEditor named Editor1. I created a custom button, but how do I get the contents of that button into my editor?

If I do Editor1.content = MYBUTTONVALUE it over rides everything i currently have in my content box.

Help! "You must rerun snapshot because current snapshot files are obsolete" every 90 minutes!

I'm having difficulty with SQL Server replication getting machines in the field to replicate correctly.   Here are the specifics of my installation:   100 remote tablet PCs using web sync to update. 1/2 running Vista, 1/2 XP (all latest updates applied) SQL Server Express 2005SP2 w/ cumulative update 6.   Server: Win2003 (all latest updates) SQL Server 2005SP2 CU6   There is 1 database. For each tablet I create a separate publication (PUB001, PUB002, PUB003, etc.) with filtered articles containing data for the tablet. Each publication has a single subscription -- the tablet to which the subscription is assigned. Subscriptions are set to expire after 14 days. Snapshot agent was run when subscription was created, and is set to run automatically every 14 days.     This is a "test" system which is scheduled to roll out into production in 2 weeks.   For the past month I have been running 6 tablets A-OK with no problems (had 6 separate publications/subscriptions on the server/tablets).   I use a stored procedure to create the publications and subscriptions. This stored procedure hasn't changed in months.   Yesterday, we added another 6 tablets w/ separate publications on the server, using the same aforementioned stored procedure.     The tablet application is set to auto-sync over the internet every 15 minutes.   Starting yesterday afternoon, at random, tablets would st
