[控件使用]GridView列表模式转到编辑模式

下面是一个比较完整的例子: 
          protected   void   Page_Load(object   sender,   EventArgs   e) 
        { 
                if   (!IsPostBack) 
                { 
                        BindData();//自定义绑定数据的函数 
                } 
                
        } 
        protected   void   GridView1_RowEditing(object   sender,   GridViewEditEventArgs   e) 
        { 
                this.GridView1.EditIndex   =   e.NewEditIndex;                           
                BindData(); 
        } 
        protected   void   GridView1_RowUpdating(object   sender,   GridViewUpdateEventArgs   e) 
        { 
                int   i   =   this.GridView1.EditIndex;　 
                string   firstName   =   ((TextBox)(GridView1.Rows[i].Cells[5].Controls[0])).Text.ToString();     
                DataKey   key   =   this.GridView1.DataKeys[e.RowIndex];     
                int   id   =   int.Parse(key[0].ToString               
                /**//* 
                  *   连接数据库，提交更新的资料 
                */ 
                SqlConnection   uptCon   =   DB.createConnection(); 
                uptCon.Open(); 
                SqlCommand   cmd   =   new   SqlCommand( "update   employees   set   FirstName= ' "   +   firstName   +   " '   where   employeeID= "   +   id,uptCon); 
                cmd.ExecuteNonQuery(); 
                Response.Write( "更新成功 "); 
                
                this.GridView1.EditIndex   =   -1; 
                BindData(); 
        } 
        protected   void   GridView1_RowCancelingEdit(object   sender,   GridViewCancelEditEventArgs   e) 
        { 
                this.GridView1.EditIndex   =   -1; 
                BindData(); 
        }
