TagPrefix and Assembly error

Expand Post »

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:

c# Syntax (Toggle Plain Text)
<%@ 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>
<%@ 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

c# Syntax (Toggle Plain Text)
:
:
:
:
 
<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>

			<controls>

        <add tagPrefix="webControls" namespace="Microsoft.Web.UI.WebControls" assembly="Microsoft.Web.UI.WebControls"   />
      </controls>
		</pages>

Re: TagPrefix and Assembly error

Is the error on your machine or on the webserver you uploaded to? the asp.net forum would be better as this is a generic c# forum, the guys in the asp.net are more dedicated to webservers
