Figure 6-6. Using an authorization scheme with a standard tab Now if you run the application while logged in as an administrator, you will see the Analysis tab, as shown in Figure 6-7. However, if you run the application while logged in as a nonadministrator, you will not see that tab, as shown in Figure 6-8.

// Build command string string commandText = "SELECT * FROM Categories"; dataCommand.CommandText = commandText; OdbcDataReader dataReader = dataCommand.ExecuteReader(); // Iterate over the query results while ( dataReader.Read() ) { Category category = new Category(dataReader.GetInt32(0), dataReader.GetString(1)); categories.Add(category); } dataConnection.Close(); } catch(Exception e) { Console.WriteLine("Error: " + e.Message); } return categories; } } } If you try to build the solution now, it will fail because the Category class is undefined. To fix that, you need to add a new class called Category.cs to the BusinessLayer project. Listing 13-18 shows the source code for the Category class. Listing 13-18. Category.cs File #region Using directives using System; using System.Collections.Generic; using System.Tesxt; #endregion namespace BusinessLayer { public class Category { private int categoryID; private string categoryName;

Figure 9-10. If you re working with multiple objects, there are extra options available that allow you to specify what to do with the original values for the properties that are changed.

Note You might have expected to see an error displayed when the nonadministrator logged in, as shown in Figure 6-8. However, in this case, rather than the authorization scheme displaying an error, the tab is simply not displayed to anyone failing the authorization scheme logic, which is preferable behavior for navigation components such as tabs.

In previous versions of NetWare with NetWare Administrator, it was only possible to change multiple Tip

properties for user objects. In OES ConsoleOne and iManager, multiple values can be changed for any type of object.

As you can see, using authorization schemes with standard tabs is an incredibly powerful way of customizing the navigation of your application dynamically at runtime depending on who is logged in (or any other criteria you prefer). It is also possible to use conditions to determine whether a standard tab should be displayed, which gives even more flexibility to dynamically customize the navigation at runtime. We ll discuss how to define conditions for navigation in the Navigation Bars section later in this chapter.

Creating a user can be a lot of work, especially if a value has to be provided for a lot of specific properties. To make creation of user objects easier, you can add default settings to the template object. This is an object in eDirectory that can be used upon creation of user objects; the user object inherits all settings that are applied to the template object. This way, creating users in eDirectory can be done a lot easier.

public Category() { } public Category(int categoryID, string categoryName) { this.categoryID = categoryID; this.categoryName = categoryName; } } } Lastly, you want to update the source for the CategoryTests.cs file as shown in Listing 13-19. Listing 13-19. Modified CategoryTests.cs File #region Using directives using System; using System.Collections; using System.Collections.Generic; using System.Data; using System.Data.Odbc; using System.Text; using NUnit.Framework; using DataLayer; #endregion namespace TestLayer { [TestFixture] public class CategoryTests { private StringBuilder connectionString; private int categoryID; public CategoryTests() { // Build connection string connectionString = new StringBuilder("Driver={Microsoft Access Driver (*.mdb)};"); connectionString.Append("DBQ=c:\\xpnet\\database\\Northwind.mdb "); }

In order to be able to use parent tabs, you need to be using a page template that supports them. Since the Buglist application currently uses One Level Tabs as the page template, you can t use parent tabs in it. Fortunately, this is quite easy to change. Just edit the page definition and select a page template that supports two levels of tabs, Two Level Tabs, as shown in Figure 6-9. Now if you run the page again, it will look similar to Figure 6-10. Since you have not defined a parent tab yet, the tab display is still quite similar to how it was before (aesthetics aside).

1. In iManager, select Roles And Tasks eDirectory Administration Create Object. 2. From the list of available object classes, select the Template object and click OK. 3. Provide a name for the template object and specify the context where you wish to create the template object. Click OK to continue. 4. A message displays stating the template was created successfully. In this screen, click Modify to get access to the properties of the template object, as shown in Figure 9-11. Now you can set all general settings for new users in your network. Click OK when finished.
