When a key press occurs, you often need to know more than just what key was pressed. It s also important to find out what other keys were held down at the same time. That means you might want to investigate the state of other keys, particularly modifiers such as Shift and Ctrl, both of which are supported on all platforms. Although you can handle the events for these keys separately and keep track of them in that way, it s much easier to use the shared Modifiers property of the Keyboard class. To test for a Keyboard.Modifier, you use bitwise logic. For example, the following code checks if the Ctrl key is currently pressed: If (Keyboard.Modifiers And ModifierKeys.Control) = ModifierKeys.Control Then message &= "You are holding the Control key." End If

QL Server 2008 continues support for the extremely useful common table expression (CTE), first introduced in SQL Server 2005. CTEs can simplify your queries to make them more readable and maintainable. SQL Server also supports self-referential CTEs, which make for very powerful recursive queries. In addition, SQL Server supports windowing functions, which allow you to partition your results and apply numbering and ranking values to the rows in the result set partitions. This chapter begins with a discussion of the power and benefits of CTEs and finishes with a discussion of SQL Server windowing functions.

The next Web Form controls we will examine are known collectively as validation controls. Unlike the other Web Form controls we ve examined, validation controls are not used to emit HTML, but are used to emit client-side JavaScript (and possibly server-side operations) for the purpose of form validation. As illustrated at the beginning of this chapter, client-side form validation is quite useful in that you can ensure that various constraints are in place before posting back to the web server, thereby avoiding expensive round-trips. Table 26-3 gives a rundown of the ASP .NET validation controls. Table 26-3. ASP .NET Validation Controls

In the Windows world, a user works with one control at a time. The control that is currently receiving the user s key presses is the control that has focus. Sometimes, this control is drawn slightly differently. For example, the Silverlight button uses blue shading to show that it has the focus. To move the focus from one element to another, the user can click the mouse or use the Tab and arrow keys. In previous development frameworks, programmers have been forced to take great care to make sure that the Tab key moves focus in a logical manner (generally from left to right and then down the window) and that the right control has focus when the window first appears. In Silverlight, this extra work is seldom necessary because Silverlight uses the hierarchical layout of your elements to implement a tabbing sequence. Essentially, when you press the Tab key you ll move to the first child in the current element or, if the current element has no children, to the next child at the same level. For example, if you tab through a window with two StackPanel containers, you ll move through all the controls in the first StackPanel and then through all the controls in the second container. If you want to take control of tab sequence, you can set the TabIndex property for each control to place it in numerical order. The control with a TabIndex of 0 gets the focus first, followed by the next highest TabIndex value (for example, 1, then 2, then 3, and so on). If more than one element has the same TabIndex value, Silverlight uses the automatic tab sequence, which means it jumps to the nearest subsequent element.
