Hi all,

I am trying to create Web Controls and i am getting this error:

Could not load file or assembly 'Microsoft.Web.UI.WebControls' or one of its dependencies. The system cannot find the file specified.


i inserted all respective directives and namespaces at the begining of the page and also in the web.config file. But it still says it cannot find the file specified.

My code goes as following:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="toolbars.aspx.cs" Inherits="toolbars" %>
<%@ Import Namespace="Microsoft.Web.UI.WebControls" %>
<%@ Register TagPrefix="webControls" 
             Namespace="Microsoft.Web.UI.WebControls" 
             Assembly="Microsoft.Web.UI.WebControls" %>

 
<html >
<head runat="server">
    <title>Untitled Page</title>
    <script  language="c#" runat="server">
        public void buttonSelected(Object sender, EventArgs e)
        {
            string name;
            name = sender.ToString();
            Response.Write(name);
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <h1>USING TOOLBAR ELEMENTS</h1>
    <webControls:Toolbar id="toolbar" runat="server" onButtonClick="buttonSelected" >
    <webControls:ToolbarButton id="home" Text="Home" />
    <webControls:ToolbarButton id="call" Text="Callus" />
    </webControls:Toolbar>
    </div>
    </form>
</body>
</html>

i inserted the tagprefix in the page elements section of the web.config file too as following

:
:
:
:

<pages enableViewStateMac="false" >
			<controls>
				<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
				<add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add tagPrefix="webControls" namespace="Microsoft.Web.UI.WebControls" assembly="Microsoft.Web.UI.WebControls"   />
      </controls>
		</pages>

The problem is exactly what the error says. The compiler cannot find Microsoft.Web.UI.WebControls in your project. I'm assuming this is the library for IE controls because i don't recognize it as part of the standard libraries. Hence, you probably need to download it, locate it on your machine and reference it in your project.
