GridView控件PageIndexChanging不工作 [英] GridView PageIndexChanging Not Working

问题描述

这似乎是一个简单的问题要问，但是我不能够以显示GridView的项目。这里是我的code：

 公共部分类TestList：System.Web.UI.Page
{
    保护无效的Page_Load（对象发件人，EventArgs的发送）
    {        如果（！Page.IsPostBack）
        {TestProject.DataAccess.Repository.Instance.Initialize（Settings.Default.TestConnection）;
            BindData（）;
        }    }    私人无效BindData（）
    {
        //限制信息！
        gvAgentList.DataSource = EntityRegistration.DataAccess.Repository.Instance.GetData（）;
        gvAgentList.DataBind（）;
    }   保护无效gvAgentList_PageIndexChanging（对象发件人，GridViewPageEventArgs E）
    {        gvAgentList.PageIndex = e.NewPageIndex;
        gvAgentList.DataBind（）;
    }   私人字符串ConvertSortDirectionToSql（SortDirection sortDirection）
   {
       字符串newSortDirection =的String.Empty;       开关（sortDirection）
       {
           案例SortDirection.Ascending：
               newSortDirection =ASC;
               打破;           案例SortDirection.Descending：
               newSortDirection =DESC;
               打破;
       }       返回newSortDirection;
   }   保护无效gvAgentList_Sorting（对象发件人，GridViewSortEventArgs E）
   {
       DataTable中的dataTable = gvAgentList.DataSource的数据表;       如果（dataTable的！= NULL）
       {
           数据视图数据视图=新的数据视图（dataTable的）;
           dataView.Sort = e.SortEx pression ++ ConvertSortDirectionToSql（e.SortDirection）;           gvAgentList.DataSource =数据视图;
           gvAgentList.DataBind（）;
       }
   }}
 

下面是在GridView的标记：

 ＆LT; ASP：内容ID =内容1ContentPlaceHolderID =HeadContent=服务器＆GT;
＆LT; / ASP：内容＆GT;
＆LT; ASP：内容ID =内容2ContentPlaceHolderID =日程地址搜索Maincontent=服务器＆GT;
    ＆所述p为H.;
    剂解释：或其可/差异无显着
    ＆LT; ASP：的UpdatePanel ID =UpdatePanel1=服务器＆GT;
    ＆LT;＆的ContentTemplate GT;
    ＆LT; ASP：GridView控件=服务器ID =gvAgentList
            AllowPaging =真
            AutoGenerateSelectButton =真AllowSorting =真背景色=＃E8E8E8
            BORDERCOLOR =＃003399边框=实边框宽度=1px的高度=375px
            WIDTH =731pxOnPageIndexChanging =gvAgentList_PageIndexChanging
            OnSorting =gvAgentList_Sorting＆GT;        ＆LT; AlternatingRowStyle前景色=＃0066CC/＆GT;
        ＆LT; HeaderStyle前景色=＃3366FF/＆GT;    ＆LT; / ASP：GridView的＆GT;   ＆LT; ASP：SqlDataSource的ID =SqlDataSource1=服务器＆GT;＆LT; / ASP：SqlDataSource的＆GT;    ＆LT; /＆的ContentTemplate GT;
    ＆LT; / ASP：的UpdatePanel＆GT;
＆LT; / ASP：内容＆GT;
 

问题是，我的GridView是不扔我任何异常，并通过断点我可以看到该功能在code叫后面。

  

我的排序也没有工作：（

解决方案

尝试

 保护无效gvAgentList_PageIndexChanging（对象发件人，GridViewPageEventArgs E）
    {        gvAgentList.PageIndex = e.NewPageIndex;
        BindData（）;
    }
 

This seems to be an easy question to ask, but I am not able to show items in GridView. Here is my code:

 public partial class TestList : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        if (!Page.IsPostBack)
        {   TestProject.DataAccess.Repository.Instance.Initialize(Settings.Default.TestConnection);
            BindData();
        }

    }

    private void BindData()
    {
        //Restriction Info!!
        gvAgentList.DataSource = EntityRegistration.DataAccess.Repository.Instance.GetData();
        gvAgentList.DataBind();
    }

   protected void gvAgentList_PageIndexChanging (object sender, GridViewPageEventArgs e)
    {

        gvAgentList.PageIndex = e.NewPageIndex;
        gvAgentList.DataBind();
    }

   private string ConvertSortDirectionToSql(SortDirection sortDirection)
   {
       string newSortDirection = String.Empty;

       switch (sortDirection)
       {
           case SortDirection.Ascending:
               newSortDirection = "ASC";
               break;

           case SortDirection.Descending:
               newSortDirection = "DESC";
               break;
       }

       return newSortDirection;
   }

   protected void gvAgentList_Sorting(object sender, GridViewSortEventArgs e)
   {
       DataTable dataTable = gvAgentList.DataSource as DataTable;

       if (dataTable != null)
       {
           DataView dataView = new DataView(dataTable);
           dataView.Sort = e.SortExpression + " " + ConvertSortDirectionToSql(e.SortDirection);

           gvAgentList.DataSource = dataView;
           gvAgentList.DataBind();
       }
   }

}

Here is the markup of the GridView:

    <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <p>
    Agent Lists:</p>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    <asp:GridView runat ="server" ID = "gvAgentList" 
            AllowPaging = "True" 
            AutoGenerateSelectButton="True" AllowSorting="True" BackColor="#E8E8E8" 
            BorderColor="#003399" BorderStyle="Solid" BorderWidth="1px" Height="375px" 
            Width="731px" OnPageIndexChanging = "gvAgentList_PageIndexChanging" 
            OnSorting="gvAgentList_Sorting" >

        <AlternatingRowStyle ForeColor="#0066CC" />
        <HeaderStyle ForeColor="#3366FF" />

    </asp:GridView>

   <asp:SqlDataSource ID="SqlDataSource1" runat="server"></asp:SqlDataSource>



    </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>

The problem is that my GridView is not throwing me any exception and through breakpoints I can see that the function is called in code behind.

My sorting is also not working :(

解决方案

Try

protected void gvAgentList_PageIndexChanging (object sender, GridViewPageEventArgs e)
    {

        gvAgentList.PageIndex = e.NewPageIndex;
        BindData();
    }
