The GridView exposes a rich formatting model that s based on styles. Altogether, you can set eight GridView styles, as described in Table 10-5. Table 10-5. Numeric Format Strings

However, it s a good idea to handle the problem in your web page and show a more suitable error message To do this, you need to handle the data source event that occurs immediately after the error If you re performing a query, that s the Selected event If you re performing an update, delete, or insert operation, you would handle the Updated, Deleted, or Inserted events instead (If you don t want to offer customized error messages, you could handle all these events with the same event handler) In the event handler, you can access the exception object through the SqlDataSourceStatusEventArgsException property If you want to prevent the error from spreading any further, simply set the SqlDataSourceStatusEventArgsExceptionHandled property to true Then, make sure you show an appropriate error message on your web page to inform the user that the command was not completed.

You can find other examples in the MSDN Help. For date or time values, there is also an extensive list. For example, if you want to write the BirthDate value in the format month/day/year (as in 12/30/05), you use the following column: <asp:BoundField DataField="BirthDate" HeaderText="Birth Date" DataFormatString="{0:MM/dd/yy}" /> Table 10-4 shows some more examples. Table 10-4. Time and Date Format Strings

Configures the appearance of the header row that contains column titles, if you ve chosen to show it (if ShowHeader is true). Configures the appearance of every data row. If set, applies additional formatting to every other row. This formatting acts in addition to the RowStyle formatting. For example, if you set a font using RowStyle, it is also applied to alternating rows, unless you explicitly set a different font through the AlternatingRowStyle. Configures the appearance of the row that s currently selected. This formatting acts in addition to the RowStyle formatting. Configures the appearance of the row that s in edit mode. This formatting acts in addition to the RowStyle formatting. Configures the style that s used for the single empty row in the special case where the bound data object contains no rows. Configures the appearance of the footer row at the bottom of the GridView, if you ve chosen to show it (if ShowFooter is true). Configures the appearance of the row with the page links, if you ve enabled paging (set AllowPaging to true).

Here s an example: protected void sourceEmployees_Selected(object sender, SqlDataSourceStatusEventArgs e) { if (eException != null) { // Mask the error with a generic message (for security purposes) lblErrorText = "An exception occurred performing the query"; // Consider the error handled eExceptionHandled = true; } }.

{0:d} {0:D} {0:f} {0:F}

Styles are not simple single-value properties. Instead, each style exposes a Style object that includes properties for choosing colors (ForeColor and BackColor), adding borders (BorderColor, BorderStyle, and BorderWidth), sizing the row (Height and Width), aligning the row (HorizontalAlign and VerticalAlign), and configuring the appearance of text (Font and Wrap). These style properties allow you to refine almost every aspect of an item s appearance. And if you don t want to

Selecting data is only half of the equation. The SqlDataSource can also apply changes. The only catch is that not all controls support updating. For example, the humble ListBox doesn t provide any way for the user to edit values, delete existing items, or insert new ones. Fortunately, ASP.NET s rich data controls including the GridView, DetailsView, and FormView all have editing features that you can switch on. The first step is to define suitable commands for the operations you want to perform, such as inserting (InsertQuery), deleting (DeleteQuery), and updating (UpdateQuery). If you know that you will allow the user to perform only certain operations (such as updates) but not others (such as insertions and deletions), you can safely omit the commands you don t need.

hard-code all the appearance settings in the web page, you can set the CssClass property of the style object reference to a stylesheet class that s defined in a linked stylesheet (see 15 for more about styles).
