User Controls : load and access properties from code behind

  

Hello,

I created a User Control :


<%@ Control Language="C#" AutoEventWireup="true" CodeFile="UCSousMenuPrincipal.ascx.cs"
    Inherits="view_usercontrols_UCSousMenuPrincipal" %>
    
<asp:DataList ID="dataListSousMenuPrincipal" runat="server" RepeatDirection="Horizontal" >
    <ItemTemplate>
        <asp:HyperLink ID="HyperLink1" runat="server"><%# Container.DataItem %></asp:HyperLink>
         
    </ItemTemplate>
</asp:DataList>


to which I added a property, so I can bind the DataList :


using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

public partial class view_usercontrols_UCSousMenuPrincipal : System.Web.UI.UserControl
{
    //Private Member    
    private object dataSource = null;
   
    protected void Page_Load(object sender, EventArgs e)
  &

Can't access App_Code class in Code Behind file

  

I have a class defined in the App_Code subdirectory:

namespace WebApplication9_App_Code
{
  public class Class1
  {
  }
}

And I have a code behind class default.aspx.cs:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace WebApplication9
{
  public partial class _Default : System.Web.UI.Page
  {
    protected void Page_Load(object sender, EventArgs e)
    {
      WebApplication9_App_Code.Class1 cls1;
    }
  }
}

I get the following compilation error:

The type or namespace name 'WebApplication9_App_Code' could not be found (are you missing a using directive or an assembly reference?)

What am I doing wrong? 

Thanks very much for your help.


form feild hints are not displaying for textboxses inside create user wizard?

  

Hi,

I'm using following JS code to display input hint box besides the textbox whenever that asp.net textbox receives focus. 

I'm doing this for a registration form and all of the textboxes are inside the asp.net create user wizard control.

<script type="text/javascript">
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      oldonload();
      func();
    }
  }
}

function prepareInputsForHints() {
	var inputs = document.getElementsByTagName("TextBox");
	for (var i=0; i<inputs.length; i++){
		// test to see if the hint span exists first
		if (inputs[i].parentNode.getElementsByTagName("span")[0]) {
			// the span exists!  on focus, show the hint
			inputs[i].onfocus = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "inline";
			}
			// when the cursor moves away from the field, hide the hint
			inputs[i].onblur = function () {
				this.parentNode.getElementsByTagName("span")[0].style.display = "none";
			}
		}
	}
addLoadEvent(prepareInputsForHints);
</script>
span.

How to access a new database ( which i created ) in isqlplus ?

Here is the page directive for the page that throws the error:

<%
@ Page language="c#" Inherits="University.AspNet.Index" CodeFile="Index.aspx.cs" %>

The code behind file Index.aspx.cs starts like this:

using University.Framework.UI;

namespace University.AspNet

{
      
public partial class Index : University.Framework.UI.HomePage

The code behind is extending this HomePage class, which is in turn an extenstion of another class University.Framework.UI.Page, which extends the System.Web.UI.Page class.

Are You in the Know?: Find Out What's New with Code Access Security in the .NET Framework 2.0

  

Unlike role-based security measures, code access security is not based on user identity. Instead, it is based on the identity of the code that is running, including information such as where the code came from. Here Mike Downen discusses the role of code access security (CAS) in .NET and outlines some key new features and changes in CAS for the .NET Framework 2.0.

Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Sid

  

Rich clients employ many of the features and conveniences of the operating system they run on, and the list of these features has been growing since the dawn of the PC. But as apps have migrated to the Web, the trend towards increasing client-side functionality has ground to a virtual halt. There are several reasons for this; chief among them are security and deployment problems. But that's all about to change. With the .NET Framework, you can participate in building the distributable rich client of the future. In this article, the author enumerates the pertinent features of .NET that will allow you to build safe, easily deployable controls. The features discussed include managed code, code access security, versioning control, Windows Forms classes, and isolation.

Security in .NET: Enforce Code Access Rights with the Common Language Runtime

  

Component-based software is vulnerable to attack. Large numbers of DLLs that are not tightly controlled are at the heart of the problem. Code access security in the Common Language Runtime of the Microsoft .NET Framework addresses this common security hole. In this model, the CLR acts as the traffic cop to assemblies, keeping track of where they came from and what security restraints should be placed on them. Another way the .NET Framework addresses security is by providing preexisting classes which have built-in security. These are the classes that are invoked in .NET when performing risky operations such as reading and writing files, displaying dialog boxes, and so on. Of course, if a component calls unmanaged code, it can bypass code access security measures. This article covers these and other security issues.

dynamically change html code when user is authenticated

  

So I have a fairly simple web site which allows an Administrator to edit some data in a database which is displayed on some web pages.


The main navigation on the site is shown in the code snippet below. The Admin link goes to a Login.aspx which allows the Administrator to log in - once authenticated they get sent to the data edit page.

So my question is, how could I dynamically add a link to the data edit page in the <ul> list below once the user is authenticated ?

This would allow the authenticated user to see links to the secure pages in the main navigation bar.


<%--Top Navigation Menu --%>
<div id="topMenu">
<ul>
<li><a href="default.aspx">Home</a></li>
<li><a href="introduction.aspx">Introduction</a></li>
<li><a href="curriculum.aspx">Curriculum</a></li>
<li><a href="times.aspx">Times & Fees</a></li>
<li><a href="staff.aspx">Staff</a></li>
<li><a href="login.aspx">Admin</a></li>
</ul>
</div><%--End of topMenu Container--%>
<div id="clear"></div><%--Floats items cleared End of Master Page--%>

What I want to happen is this

 

When the CreatedUser Event is fired, I  want a Modal Popup to show up with a message Processing your registration.

once the registration code is processed it will close and the users get redirected.

file upload in Create User Wizard Created User event with UpdatePanel Tag wont work?

  

Hi,

In my Create User Wizard1 Created User Wizard Event, I am collecting extra information from text boxes and allowing

the user to uplad a file.

 

 

I have put the Submit button within an Update Panel Tag but since I have done this it does not work.
