You define the InsertCommand, DeleteCommand, and UpdateCommand in the same way you define the command for the SelectCommand property by using a parameterized query. For example, here s a SqlDataSource that defines a basic update command that updates every field: <asp:SqlDataSource ID="sourceEmployees" runat="server" ProviderName="System.Data.SqlClient" ConnectionString="<%$ ConnectionStrings:Northwind %>" SelectCommand="SELECT EmployeeID, FirstName, LastName, Title, City FROM Employees" UpdateCommand="UPDATE Employees SET FirstName=@FirstName, LastName=@LastName, Title=@Title, City=@City FROM Employees WHERE EmployeeID=@EmployeeID"> </asp:SqlDataSource> In this example, the parameter names aren t chosen arbitrarily. As long as you give each parameter the same name as the field it affects and preface it with the @ symbol (so FirstName because @FirstName), you don t need to define the parameter. That s because the ASP.NET data controls automatically submit a collection of parameters with the new values before triggering the update. Each parameter in the collection uses this naming convention. To try this, create a page with the SqlDataSource shown previously and a linked GridView control. Now, take the following steps to enable editing: 1. Select the GridView. In the smart tag, choose the Add New Column link. 2. In the Choose a Field Type box, select CommandField. Then, select the Edit/Update check box and the Show Cancel Button check box. Make sure all other check boxes are unchecked. 3. Click OK to add the column with editing controls. When you complete these steps, the GridView editing controls appear in an additional column. When you run the page and the GridView is bound and displayed, the edit column shows an Edit link next to every record. When clicked, this link switches the corresponding row into edit mode. All fields are changed to text boxes (with the exception of read-only fields), and the Edit link is replaced with an Update link and a Cancel link (see Figure 9-10).

Figure 9-10. Editing with the GridView The Cancel link returns the row to its initial state. The Update link passes the values to the SqlDataSource.UpdateParameters collection (using the field names) and then triggers the SqlDataSource.Update() method to apply the change to the database. Once again, you don t have to write any code.

When setting style properties, you can use two similar syntaxes (and you ll see both of them in this chapter) First, you can use the object-walker syntax to indicate the extended style properties as tag attributes Here s an example: <asp:GridView runat="server" ID="grid" ItemStyle-ForeColor="DarkBlue" .. /> .. </asp:GridView> Alternatively, you can add nested tags, as shown here: <asp:GridView runat="server" ID="grid" ..> <ItemStyle ForeColor="DarkBlue" .. /> .. </asp:GridView> Both of these approaches are equivalent However, you make one other decision when setting style properties You can specify global style properties that affect every column in the grid (as in the previous examples), or you can define column-specific styles To create a column-specific style, you need to add style attributes or a nested tag inside the appropriate column tag, as shown here: <asp:GridView runat="server" ID="grid" ..> <Columns> <asp:BoundField DataField="EmployeeID" HeaderText="ID" ItemStyle-Width="30px" /> .. </Columns> </asp:GridView> Or equivalently, you can use a nested tag: <asp:GridView runat="server" ID="grid" ...

yyyy-MM-dd HH:mm:ss MMMM dd M/d/yyyy HH:mm:ss aa (depends on locale-specific settings)

You can create similar parameterized commands for the DeleteCommand and InsertCommand. To enable deleting and inserting, you need to add a column to the GridView that has the ShowInsertButton and ShowDeleteButton properties set to true.

> <Columns> <asp:BoundField DataField="EmployeeID" HeaderText="ID"> <ItemStyle Width="30px"> </asp:BoundField> .. </Columns> </asp:GridView> This technique is often used to define specific column widths If you don t define a specific column width, ASPNET makes each column just wide enough to fit the data it contains (or, if wrapping is enabled, to fit the text without splitting a word over a line break) If values range in size, the width is determined by the largest value or the width of the column header, whichever is larger However, if the grid is wide enough, you might want to expand a column so it doesn t appear to be crowded against the adjacent columns In this case, you need to explicitly define a larger width Here s a fully formatted GridView tag: <asp:GridView ID="GridView1" runat="server" DataSourceID="sourceEmployees" Font-Names="Verdana" Font-Size="X-Small" ForeColor="#333333" CellPadding="4" GridLines="None" AutoGenerateColumns="False"> <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> <RowStyle BackColor="#FFFBD6" ForeColor="#333333" /> <AlternatingRowStyle BackColor="White" />.
