编辑页面如下图:

页面test.aspx代码如下:

<html>

<head runat="server">

    <title>无标题页</title>

</head>

<body>

    <form id="form1" runat="server">

    <div>



        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowEditing="GV_EDIT"    OnRowUpdating="GV_UPDATE" OnRowCancelingEdit="GV_CANCEL">

            <Columns>

                <asp:TemplateField HeaderText="记录ID">

                    <ItemStyle Width="150px" />

                    <ItemTemplate>

                        <asp:Label ID="Label1" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"JLXH")%>'></asp:Label>

                    </ItemTemplate>

                    <EditItemTemplate>

                        <asp:TextBox ID="JLID_TXT" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"JLXH")%>'>

                        </asp:TextBox>

                    </EditItemTemplate>

                </asp:TemplateField>

                <asp:CommandField ShowEditButton="true" ShowCancelButton="true" UpdateText="保存"/>

            </Columns>

        </asp:GridView>



    </div>

    </form>

</body>

</html>

后台代码test.aspx.cs如下:

public partial class scyx_cjxmmbwh_test : System.Web.UI.Page

{

    DataTable dt = new DataTable();

    protected void Page_Load(object sender, EventArgs e)

    {

        //绑定显示模板的gridview数据

        string sql1 = "select * from cj_scyx_table_cjxmmbmx";

        dt = DBDelegate.ExecuteTable(GetDatabaseProperty.GetDatabase(), sql1);

        this.GridView1.DataSource = dt;

        this.GridView1.DataBind();

    }

    /// <summary>

    /// gridview的编辑事件

    /// </summary>

    /// <param name="sender"></param>

    /// <param name="e"></param>

    protected void GV_EDIT(object sender, GridViewEditEventArgs e)

    {

        this.GridView1.EditIndex = e.NewEditIndex;

        this.GridView1.DataSource = dt;

        this.GridView1.DataBind();



    }

    /// <summary>

    /// gridview的取消编辑事件

    /// </summary>

    /// <param name="sender"></param>

    /// <param name="e"></param>

    protected void GV_CANCEL(object sender, GridViewCancelEditEventArgs e)

    {



        this.GridView1.EditIndex = -1;

        this.GridView1.DataSource = dt;

        this.GridView1.DataBind();

    }

    /// <summary>

    /// gridview的更新事件

    /// </summary>

    /// <param name="sender"></param>

    /// <param name="e"></param>

    protected void GV_UPDATE(object sender, GridViewUpdateEventArgs e)

    {



            string id = this.GridView1.Rows[e.RowIndex].Cells[0].Text.Trim();

            string updateId = ((TextBox)this.GridView1.Rows[e.RowIndex].Cells[0].FindControl("JLID_TXT")).Text;

            Response.Write("<script>alert('" + updateId + "')</script>");

            //存数据库的方法省略

            string sql = "select * from cj_scyx_table_cjxmmbmx";

            DataTable dt1 = DBDelegate.ExecuteTable(GetDatabaseProperty.GetDatabase(), sql);

            this.GridView1.EditIndex = -1;

            this.GridView1.DataSource = dt1;

            this.GridView1.DataBind();

    }

}
一个简单的例子，呵呵~~~
