Ajax Control Toolkit Compile error ASP.NET

Question

I added AjaxControlToolkit version 7.1213 from nuget, and I have vs 2012 with .net 4.5 I try to use calenderextender in my website like this

<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajaxToolkit:ToolkitScriptManager>
<asp:TextBox ID="birthtxt" runat="server" Style="width: 95%;" />
<ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server"></ajaxToolkit:CalendarExtender>

when trying to debug the project I got the following errors:

Error   1   The type 'System.Web.UI.ScriptManager' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.


Error   2   The type 'System.Web.UI.ExtenderControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

        <add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" />
      </controls>
    </pages>

Looks like you haven't added the AjaxControlToolkit assembly to the Assemblies section. Could you try adding it in and then retesting?

EDIT: To get the PublicKeyToken, open Visual Studio Command Prompt, cd to the directory where your DLL is located and then issue below command:

sn -Tp AjaxControlToolkit.dll

how to get public key token??

Feras Salim Over a year ago

I tried that and got this Microsoft (R) .NET Framework Strong Name Utility Version 4.0.30319.17929 Copyright (c) Microsoft Corporation. All rights reserved. Failed to convert key to token -- Invalid assembly public key.

shree.pat18 Over a year ago

Did you use Tp with capital T? The flag is case-sensitive, so if you use lower case t you will get this issue.

Feras Salim Over a year ago

I did all things you said and got this when retesting The following assembly has dependencies on a version of the .NET Framework that is higher than the target and might not load correctly during runtime causing a failure: HtmlAgilityPack, Version=1.4.6.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a. The dependencies are: mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089; System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089; System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.

If am not wrong, this may be your issue take away below line from your web.config file

<add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" />

and put that in top of your source page, and don't forget to put your tagprefix in last which mean after namespace declaration.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

and change like this in source page, because no connection between ajaxtoolkit and textbox.For that you have to use 'TargetControlID'

<ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="birthtxt">
    </ajaxToolkit:CalendarExtender>

UPDATE

change your webconfig file as,

<pages>
<controls>

<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions,Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" 
        tagPrefix="ajaxToolkit"/>
</controls>
</pages>
