C# 使用Datatable的Gridview分页-不工作

我有一个gridview，它有分页功能，但当我点击第2页时，页面刷新并返回第一页，页面链接也保留在第1页上

任何帮助都将不胜感激：）

页面索引交换：-

public void GridView1_PageIndexChanging(object   
sender,GridViewPageEventArgse)
{
        GridView x = ((GridView)sender);
        GridView1.DataSource = ViewState["dt_data"];


        if (e.NewPageIndex > -1 && e.NewPageIndex <= x.PageCount)
        {
            x.PageIndex = e.NewPageIndex+1;
        }
        else
        {
            e.NewPageIndex--;
        }
   GridView1.DataBind();
}

---

修改页面索引交换代码

public void GridView1_PageIndexChanging(object sender,GridViewPageEventArgse)
{
    GridView1.DataSource = (DataTable)ViewState["dt_data"];
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataBind();
}

设置GridView的AllowPaging=“True”属性以启用分页

设置PageSize属性以说明将在屏幕上显示多少条记录 每一页

HTML标记：

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True"   PageSize="20" 
    onpageindexchanging="GridView1_PageIndexChanging"
    onrowcommand="GridView1_RowCommand" AutoGenerateColumns="False" 
    onrowdatabound="GridView1_RowDataBound"> 
</asp:GridView>

private void BuildResults()
{
DataTable dt01 = obSectionDefinition.List(_criteria.AuditDefinitionGUID, _criteria.ParentGUID, _criteria.ShowObsolete);

// GridView1.PageSize = 20;
// ViewState["dt_data"] = dt01;
 GridView1.DataSource = dt01;
 GridView1.DataBind();
}


public void GridView1_PageIndexChanging(object  sender,GridViewPageEventArgs e)
{
     GridView1.PageIndex = e.NewPageIndex;
    BuildResults();
}

私有void BuildResults（）
{
DataTable dt01=obSectionDefinition.List（_criteria.AuditDefinitionGUID、_criteria.ParentGUID、_criteria.showObsetable）；
//GridView1.PageSize=20；
//ViewState[“dt_数据”]=dt01；
GridView1.DataSource=dt01；
GridView1.DataBind（）；
}
public void GridView1_PageIndexChanging（对象发送方，GridViewPageEventArgs e）
{
GridView1.PageIndex=e.NewPageIndex；
BuildResults（）；
}

我收到了一个响应。在页面的其他位置写入，这导致分页失败-将其删除，现在可以工作了

为什么要增加e.NewPageIndex？这也不起作用-有东西阻止分页工作

 protected void Page_Load(object sender, EventArgs e)
 {
        if (!this.IsPostBack)
        {
               BuildResults();
        }
  }

public void GridView1_PageIndexChanging(object sender,GridViewPageEventArgse)
{
    GridView1.DataSource = (DataTable)ViewState["dt_data"];
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataBind();
}

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True"   PageSize="20" 
    onpageindexchanging="GridView1_PageIndexChanging"
    onrowcommand="GridView1_RowCommand" AutoGenerateColumns="False" 
    onrowdatabound="GridView1_RowDataBound"> 
</asp:GridView>

private void BuildResults()
{
DataTable dt01 = obSectionDefinition.List(_criteria.AuditDefinitionGUID, _criteria.ParentGUID, _criteria.ShowObsolete);

// GridView1.PageSize = 20;
// ViewState["dt_data"] = dt01;
 GridView1.DataSource = dt01;
 GridView1.DataBind();
}


public void GridView1_PageIndexChanging(object  sender,GridViewPageEventArgs e)
{
     GridView1.PageIndex = e.NewPageIndex;
    BuildResults();
}
