C#中GridView动态添加列的实现方法

protected void Page_Load(object sender, EventArgs e) {   TemplateField mycustomField = new TemplateField();  //创建列实例   mycustomField.ShowHeader = true;  // 设置属性   LinkButton lb = new LinkButton();   lb.Text = "Delete";   mycustomField.HeaderTemplate = new GridViewTemplate(DataControlRowType.Header, "删除");   mycustomField.ItemTemplate = new GridViewTemplate(DataControlRowType.DataRow, "", lb);   TabelContentListGridView.Columns.Add(mycustomField);  //添加列到TabelContentListGridView控件   // 这种绑定翻页会丢失数据   // 下面的绑定数据可以保持 不过也要清零列不然后出现很多重复列   // TabelContentListGV.Columns.Clear(); //清零列   // System.Web.UI.WebControls.BoundField customField = new BoundField();   // customField.DataField = dt.Columns[i].ColumnName;   // customField.HeaderText = dt.Columns[i].ColumnName;   // customField.ItemStyle.CssClass = dt.Columns[i].ColumnName;   // TabelContentListGridView.Columns.Add(customField); }
