当我更改页面索引时，ASP.net gridview 分页索引消失

Question

这是我的代码：当我更改寻呼机的索引时，我得到了正确的数据，但寻呼机页脚消失了：

<asp:GridView ID="GridView1" runat="server" PageSize="4" AllowPaging="true"     AllowSorting="true" AutoGenerateColumns="false" OnRowEditing="GridView1_RowEditing" DataKeyNames="id" OnRowCancelingEdit="GridView1_RowCancelingEdit" AlternatingRowStyle-CssClass="eventRowStyle" OnPageIndexChanging="GridView1_PageIndexChanging" OnPageIndexChanged="GridView1_PageIndexChanged">

代码隐藏：

protected void Page_Load(object sender, EventArgs e)
{
        if (!IsPostBack)
        {
            GridViewDBEntities model = new GridViewDBEntities();
            var query = from p in model.userTbls select p;
            GridView1.DataSource = query;
            GridView1.DataBind();
        }
    }

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridViewDBEntities model = new GridViewDBEntities();
    var query = (from p in model.userTbls orderby p.id ascending select p).Skip((e.NewPageIndex) * GridView1.PageSize).Take(GridView1.PageSize);
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataSource = query;
    GridView1.DataBind();
}

您可以强制您的寻呼机保持可见！

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
    GridView1.BottomPagerRow.visible = True 

顺便说一句，您已经定义了 pageSize 并将 Paging 设置为 true，所以我认为这样就可以了

    protected void Page_Load(object sender, EventArgs e)
   {
        if (!IsPostBack)
        {
           BindGrid();

        }
    }
       private void BindGrid()
        {
            GridViewDBEntities model = new GridViewDBEntities();
            var query = from p in model.userTbls select p;
            GridView1.DataSource = query;
            GridView1.DataBind();
        }

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
  //  GridViewDBEntities model = new GridViewDBEntities();
   // var query = (from p in model.userTbls orderby p.id ascending select //p).Skip((e.NewPageIndex) * GridView1.PageSize).Take(GridView1.PageSize);
    GridView1.PageIndex = e.NewPageIndex;
   // GridView1.DataSource = query;
    //GridView1.DataBind();
     BindGrid();
}

如果您必须实现某些必须编辑网格或插入记录的功能，删除!IsPostback 稍后会导致问题，更好的方法是创建一个Bind 方法并根据要求使用它。
