gridview 自定义分页在转到某页时无数据,在线等,谢谢
问题:在goto page 中任意选一个数字后,gridview中没有数据出来.但用first next 等按钮操作翻页则可以.
代码:listnews.aspx:
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "Listnews.aspx.cs " Inherits= "Listnews " %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head runat= "server ">
<title> 无标题页 </title>
</head>
<body>
<form id= "form1 " runat= "server ">
<div>

<asp:BoundField DataField= "topic " HeaderText= "topic " SortExpression= "topic " />

<asp:ButtonField Text= "Delete " ButtonType= "Button " CommandName= "Delete " />

[解决办法]
gridView.PageIndex = ddlPageSelector.SelectedIndex; gridView.DataBind();==> gridView.PageIndex = ddlPageSelector.SelectedIndex; BindGrid();这里
[解决办法]
楼上两位正解,楼上的还需要再写代码,幕白兄的不用再写代码了.
[解决办法]
把 ddlPageSelector.SelectedIndexChanged 移到页面中处理
