Thus, if you use multiple anonymous methods in the context of a method, they all share the same instantiated class When you call a method that creates an anonymous method, a class instance is created each and every time the method is called Therefore, the method BuilderBuildWhatAmI() instantiates an anonymous method class that is returned to the caller What is misleading about all of this is that an anonymous method is a class instantiation, although the new identifier has not been used..

Execute the project and test the updated functionality to make sure that it still works. Template columns are useful because they give you full control over how the column looks and behaves. In this exercise, you modified the TextBox control used for editing the department description, but now you can use the same technique to change any field in the table. Because you can also change the names of the controls inside your template, you can now access them by name, instead of by location: string description = ((TextBox)grid.Rows[e.RowIndex].FindControl(" descriptionTextBox")).Text; This piece of code demonstrates how to obtain a reference of the TextBox control named descriptionTextBox, convert its Control reference to a TextBox reference, and extract its contents from there. You ll see some other examples of template columns later in this chapter when you ll use CheckBox controls instead of Label and TextBox controls for displaying the value of True/False fields.

Note Other than the introduction of .NET generics, the .NET virtual machine has not changed that much,

The category administration bits are similar to what you did for departments, so we won t need to explain much this time. The main player in the whole categories administration part is the AdminCategories.aspx Web Form, but first you need to write the data tier and business tier code that will support its functionality.

but C# programming has changed quite a bit. Many of the changes in the C# programming language are to simplify techniques that programmers commonly employ. This means that the generated code will behave like the code that you would have needed to write yourself if the language features did not exist.

1. First you ll create the stored procedures that you need to add to your BalloonShop database: CatalogCreateCategory, CatalogUpdateCategory, and CatalogDeleteCategory. The fourth stored procedure that you ll use, CatalogGetCategories, already exists in the database. Add these stored procedures to the BalloonShop database. These stored procedures will be covered in the following sections. CatalogCreateCategory adds a new category to the database. Apart from the name and description of the new category, you also need a DepartmentID, which specifies the department the category belongs to. Note that you don t need to specify a CategoryID (in fact, you can t) because CategoryID is an IDENTITY column in the Category table, and its value is automatically generated by the database when inserting a new record. CREATE PROCEDURE CatalogCreateCategory (@DepartmentID int, @CategoryName nvarchar(50), @CategoryDescription nvarchar(50)) AS INSERT INTO Category (DepartmentID, Name, Description) VALUES (@DepartmentID, @CategoryName, @CategoryDescription) 2. The UpdateCategory stored procedure updates the name and description of a category. CREATE PROCEDURE CatalogUpdateCategory (@CategoryID int, @CategoryName nvarchar(50), @CategoryDescription nvarchar(1000)) AS UPDATE Category SET Name = @CategoryName, Description = @CategoryDescription WHERE CategoryID = @CategoryID 3. CatalogDeleteCategory deletes a certain category from the database. If the category has products that belong to it, the database raises an error because the deletion affects the database integrity remember that you implemented the One-to-Many relationship between the Category and Product tables using a foreign-key relationship back in 5. In this case, the error is trapped in the business tier, which returns an error code to the presentation tier, which informs the user that an error has occurred. CREATE PROCEDURE CatalogDeleteCategory (@CategoryID int) AS DELETE FROM Category WHERE CategoryID = @CategoryID
