请问 C#中if (e.Row.RowType == DataControlRowType.DataRow)和((LinkButton)(e.Row.Cells[6].Controls[0])).Attributes.Add("onclick", "return confirm('确定要删除吗？')");指什么，越详细越好。

Answer 1

if (e.Row.RowType == DataControlRowType.DataRow)
就是指这个行是数据行,gridview里在行包括标题行,编辑行等等..所以需要用这个判断行在类型.((LinkButton)(e.Row.Cells[6].Controls[0])).Attributes.Add("onclick", "return confirm('确定要删除吗？')");这个是找到当前行的第7个单元格的第一个控件(返回的可能是object类型或者是control类型,我忘记轼),所以必须向上转换为LinkButton.之后给该控件添加一个特性,就是js
当删除的时候显示对话框.

Answer 2

GridView每一行的數據綁定都會執行到 GridView_RowDataBound 這個方法, 
"if (e.Row.RowType == DataControlRowType.DataRow)"  這行代碼的意思就是, 過濾掉非數據行, 就是執行到
表頭 或 表尾, 則不會進入if之內.
((LinkButton)(e.Row.Cells[6].Controls[0])).Attributes.Add("onclick", "return confirm('确定要删除吗？')");
這一行呢, 就是Grid中有個刪除按鈕(linkbutton), 找到這個刪除按鈕, 給它添加一個屬性, 在單擊 "刪除"按鈕
時出現提示 "确定要删除吗？", 如果點擊 "確定" , 則會返回 "true", 如果點擊 "取消" , 則返回 "false"
