this case, the columns you explicitly define are added before the autogenerated columns. However, for the most flexibility, you ll usually want to explicitly define every column.

Note As you ll soon see, often a gap exists between what you can do and what you should do. In most professional applications, you ll need to write and fine-tune your data access code for optimum performance or access to specific features. That s why you ve spent so much time learning how ADO.NET works, rather than jumping straight to the data source controls.

Each column can be any of several column types, as described in Table 16-1. The order of your column tags determines the left-to-right order of columns in the GridView. Table 16-1. Column Types

The data source controls include any control that implements the IDataSource interface. The .NET Framework includes the following data source controls:

vb.net qr code reader free, rdlc ean 13, asp.net upc-a, ms word barcode generator free, crystal reports barcode 128, word aflame upc lubbock

This column displays text from a field in the data source. This column displays a button in this grid column. This column displays a check box in this grid column. It s used automatically for true/false fields (in SQL Server, these are fields that use the bit data type). This column provides selection or editing buttons. This column displays its contents (a field from the data source or static text) as a hyperlink. This column displays image data from a binary field (providing it can be successfully interpreted as a supported image format). This column allows you to specify multiple fields, custom controls, and arbitrary HTML using a custom template. It gives you the highest degree of control but requires the most work.

SqlDataSource: This data source allows you to connect to any data source that has an ADO.NET data provider. This includes SQL Server, Oracle, and OLE DB or ODBC data sources. When using this data source, you don t need to write the data access code. AccessDataSource: This data source allows you to read and write the data in an Access database file (.mdb).

The most basic column type is BoundField, which binds to one field in the data object. For example, here s the definition for a single data-bound column that displays the ProductID field: <asp:BoundField DataField="ProductID" HeaderText="ID" /> This tag demonstrates how you can change the header text at the top of a column from ProductID to just ID. Here s a complete GridView declaration with explicit columns:

At the end of that e-mail will be a link to get your access key, which you should follow; you will need this key shortly The URL for the WSDL for the Amazon Web Services API is currently http:// webservicesamazoncom/AWSECommerceService/AWSECommerceServicewsdl, and the file is immense You re going to use only a very small subset of this WSDL, specifically the ItemSearch operation This method has some nested parameters First, the Amazon Web Services request requires the parameter AWSAccessKeyId to be passed along with another parameter named Request Request is an associative array of data and can contain many optional keys, which are well documented on the Amazon Web Services site For this example, you will search for this book by Title and Publisher, using the SearchIndex 'Books' and asking for a small ResponseGroup back from the server.

Note Access databases do not have a dedicated server engine (like SQL Server) that coordinates the

<asp:GridView ID="GridView1" runat="server" DataSourceID="sourceProducts" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="ProductID" HeaderText="ID" /> <asp:BoundField DataField="ProductName" HeaderText="Product Name" /> <asp:BoundField DataField="UnitPrice" HeaderText="Price" /> </Columns> </asp:GridView> Explicitly defining columns has several advantages: You can easily fine-tune your column order, column headings, and other details by tweaking the properties of your column object. You can hide columns you don t want to show by removing the column tag. (Don t overuse this technique, because it s better to reduce the amount of data you re retrieving if you don t intend to display it.) You ll see your columns in the design environment (in Visual Studio). With automatically generated columns, the GridView simply shows a few generic placeholder columns. You can add extra columns to the mix for selecting, editing, and more.

actions of multiple people and ensures that data won t be lost or corrupted. For that reason, Access databases are best suited for very small websites, where few people need to manipulate data at the same time. A much better small-scale data solution is SQL Server Express, which is described in 15.
