C# s anonymous type feature allows you to automatically declare an immutable tuple type using a very simple and succinct syntax . A tuple type1 is a type that contains a collection of properties that are usually related to each other in some way . In the top line of the code below, I am defining a class with two properties (Name of type String, and Year of type Int32), constructing an instance of this type, and setting its Name property to "Jeff" and its Year property to 1964 .

The DetailsView layout supports several properties that fall into the following categories: behavior, appearance, style, state, and templates. Table 7-11 lists them.

Loading the control state and the view state In ASP.NET 2.0, the control state is a sort of private view state that each control is responsible for maintaining. Unlike the view state, the control state can t be modified programmatically outside the control and can t be turned off. The control state is loaded before the view state. Both steps fire no events but can be customized, overriding a couple of protected methods. Loading postback data The posted values are processed and their ID matched against the ID of all declared controls. If a match is found, the posted value updates the state of the control. (How this happens for a specific control depends on the control s implementation of the IPostBackDataHandler interface.) Page preloading The PreLoad event occurs when the page is finished processing any posted values. You handle this event if you need to perform any operation before the page loading phase begins. Page loading The Load event is fired recursively for all constituent controls and then for the page. Before the loading stage ends, a number of interesting actions take place. The page makes a second attempt to find a match between posted values and page controls. This attempt is designed to load any available state into dynamic controls created or restored in the Load event. If the page has a callback event handler, the event is raised at this time. Finally, if the posted values modify the properties of some child controls that require notification of changes, the related postback change notification events are fired. For example, if the posted values modify the Text property of a TextBox control, the TextChanged server event is fired. Postback events The page executes the server-side code associated with the client-side event (i.e., a click) that caused the page to post back. This step is the core of the ASP.NET event model. End of page loading The LoadComplete occurs to mark the end of the preliminaries. From now on, the page enters its rendering phase. Prerendering Before the page fires the PreRender event, it ensures that all needed child controls have been created. The PreRender event is first fired for the page and then recursively for all children. At the end of the loop, the page fires the PreRenderComplete event and saves personalization data, control, and view state.

Virtually everything that I ve mentioned in the context of column charts also applies to bar charts . From the technical point of view, the two types are very similar, and you ll hardly find any differences in the relevant dialog boxes . For this reason, I would like to refer you to the information already provided in the context of column charts and consider the explanations for bar charts as a detailed recapitulation . If you find new information that was not discussed for the column charts, the same rule applies in reverse: working with a general rotation of 90 , characteristics and formatting variants of column and bar charts can be interchangeable, with just few exceptions .

You can type the link in your browser, but it s easier to simply Google sharepoint spreadsheet add-in for excel. (Include SharePoint in the search string there are a lot of spreadsheet add-ins.) The first item in the search results Download Details: Windows SharePoint Services Add-in: Spreadsheet is the link to the download page. Click the link. Follow these steps to install the add-in: 1. On the download page, click the Download button. 2. When the File Download - Security Warning dialog box appears, choose Run to start the install. 3. Review the Spreadsheet Web Part Add-in license agreement and click Yes. 4. In the next dialog box, click Browse to choose a location for the add-in. There are two good choices. The default add-ins folder is C:\Documents and Settings\your user name\Application Data\Microsoft\AddIns. The add-ins folder for Office 2003, C:\Program Files\Microsoft Office\OFFICE11\ADDINS, is accessible to all users. Choose one of these locations (or another location if you prefer). Click OK to save the add-in in the folder. After the add-in is saved, a message box tells you how to install the add-in in Excel: 1. In Excel, choose Tools Add-Ins to open the Add-ins dialog box, shown in Figure 10-2. 2. Click the Browse button and locate the SpreadsheetWebpart.xla file. Select the file and click OK to install the add-in.

In the preceding two chapters, you will have implemented a functional product catalog for HatShop. However, the site still lacks the all-important search feature. The goal in this chapter is to allow the visitor to search the site for products by entering one or more keywords. You ll learn how to implement search results rankings and how to browse through the search results page by page. You ll see how easy it is to add new functionality to a working site by integrating the new components into the existing architecture.

Earlier, I mentioned that you should always use Load and avoid using LoadFrom whenever possible. One reason is that LoadFrom is much slower than Load because it calls Load internally, which has to apply policy and scan several disk locations. Another reason is that an assembly loaded with LoadFrom is treated like a "data file," and if your AppDomain does load two identical assembly files from different paths, you re wasting a lot of memory and also hurting run time performance. Calling Load ensures that performance is as good as it can be and that an assembly isn t loaded more than once into an AppDomain. Whenever you re about to place a call to LoadFrom, think about your application and try to figure out a way to change it so that Load will work instead. Of course, there will be times when Load simply won t do and using LoadFrom is necessary (such as in the SomeTool.exe example). Certainly, if you can t use Load, use LoadFrom instead just be careful.
