Answer 1

/// <summary>
/// userGridView 的摘要说明
/// </summary>
public class userGridView:GridView
{
    public string table;
    public string tablename;
public userGridView()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
}

Answer 2

网上搜索以后发现
            MakeGrid(ref tm);
            CreateDataGridForm.Controls.Add(tm);
位置颠倒填写以后分页问题就解决了,不过在生成的页面上点击排序码或者页码GV就消失了

Answer 3

把MakeGrid拆成两半一般在ispostback里面一半在外面 现在可以正常排序分页了
但是更新的时候始终无法触发RowUpdating 点击更新按钮也不报错 我看了下源代码 js里面_dopostback第二个参数是空的 不知道怎么回事

Answer 4

你把 GridView的排序禁掉GridView.cloumn.sort.....=false;
