C# GridView客户端分页不工作

处理来自其他程序的数据，例如，在这段代码中，我使用来自其他程序的类似随机数数组的查询数据。查询到DataTable并绑定到GridView+添加所有行删除按钮

在删除按钮上单击-此按钮为非活动使用按钮。已启用=false；和UpdatePanel等按钮点击我有旧数组都很好。 但当我使用分页时，每次都有新的数组

如何修复它？我需要-在第一页中单击按钮-它们变为非活动状态，然后我选择第二页，然后返回第一页，并查看带有非活动按钮的旧阵列

您基本上需要在请求之间存储数据源。一种选择是使用变量：

public partial class WebForm1 : System.Web.UI.Page
    {
        private DataTable _Source;

        public WebForm1()
        {
        }

        private void ResetData()
        {
            _Source = new DataTable();
            _Source.Columns.Add("Name", typeof(string));
            _Source.Columns.Add("Number", typeof(string));
            Random rn = new Random();
            for (int t = 0; t < 100; t++)
            {
                _Source.Rows.Add(rn.Next(1, 10).ToString(), rn.Next(1, 10).ToString());
            }

            Session["data"] = _Source;
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                ResetData();
                GridView1.DataBind();
            }
            _Source = Session["data"] as DataTable;
        }

        protected void GridView1_RowDeleted(object sender, GridViewDeletedEventArgs e)
        {

        }

        protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            ((DataTable)Session["data"]).Rows.RemoveAt(e.RowIndex);
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            ResetData();
            GridView1.DataBind();
        }

        protected void GridView1_DataBinding(object sender, EventArgs e)
        {

            GridView1.DataSource = _Source;
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            var button = sender as Button;
            button.Enabled = false;
            var hidden = button.Parent.FindControl("HiddenField2") as HiddenField;
            var name = hidden.Value;
            DeletForName(name);
        }

        protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {

            GridView1.PageIndex = e.NewPageIndex;
            GridView1.DataBind();

        }
        private void DeletForName(string name)
        {

            foreach (DataRow row in _Source.Rows)
                if (row["Name"].Equals(name))
                {
                    _Source.Rows.Remove(row);
                    break;
                }
        }
    }

如果您想从表中删除该项，但仍然禁用已删除行索引处的按钮，那么这将有点复杂。如果是这样的话，请告诉我，我可以试着帮你，但看起来更像是你想要的

非常感谢！它是有效的，但按钮不是。例如，我在第一页点击删除按钮-确认-按钮变为非活动状态，我选择第二页，然后返回到第一页-此按钮是活动的。我没有意识到我可以对自己的帖子发表评论，抱歉。请参阅上面我的编辑以回应您的评论。希望我在正确的轨道上，让我知道。另外，请记住，在示例代码中，delete函数实际上不能正常工作，因为datatable中的name列不包含唯一的数据@汉克斯，我试着在我的解决方案中这样做。

public partial class WebForm1 : System.Web.UI.Page
    {
        private DataTable _Source;

        public WebForm1()
