用编码实现gridview的创建！（一）（转www.asp.net）

完全用编码实现gridview创建和clounms的添加。 原理大概是三部分： datasource对象的设置和gridview对象的设置和Columns的添加。看完后感觉不难，但是人家的思路的确值得我们推敲。 这是第一部分，等第二部分出来了，马上更新。 protected void Page_Load(object sender, EventArgs e) { SqlDataSource1.ConnectionString = @"data source=.;initial catalog=northwind;integrated =true"; SqlDataSource1.SelectCommand = "select employeeID,FirstName,LastName from employees"; SqlDataSource1.UpdateCommand = "update employees set firstname=@FirstName,lastname=@LastName where employeeid=@EmployeeID"; SqlDataSource1.UpdateParameters.Add("@FirstName", ""); SqlDataSource1.UpdateParameters.Add("@LastName", ""); SqlDataSource1.UpdateParameters.Add("@EmployeeID", ""); if (!IsPostBack) { GridView1.DataSourceID = "SqlDataSource1"; GridView1.AutoGenerateColumns = false; GridView1.DataKeyNames = new string[] { "EmployeeID" }; GridView1.AllowPaging = true; GridView1.AllowSorting = true; GridView1.PageSize = 5; BoundField bf1 = new BoundField(); BoundField bf2 = new BoundField(); BoundField bf3 = new BoundField(); bf1.HeaderText = "Employee ID"; bf1.DataField = "EmployeeID"; bf1.ReadOnly = true; bf1.SortExpression = "EmployeeID"; bf2.HeaderText = "First Name"; bf2.DataField = "FirstName"; bf2.SortExpression = "FirstName"; bf3.HeaderText = "Last Name"; bf3.DataField = "LastName"; bf3.SortExpression = "LastName"; CommandField cf = new CommandField(); cf.ButtonType = ButtonType.Button; cf.ShowCancelButton = true; cf.ShowEditButton = true; GridView1.Columns.Add(bf1); GridView1.Columns.Add(bf2); GridView1.Columns.Add(bf3); GridView1.Columns.Add(cf); } }
