今天上午研究一個多小時了終於出來了。
前臺頁面
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

<body>
<form id="form1" runat="server">

然後後臺綁定

//獲取加載時的table
public DataTable getTable() {

DataRow dr;
for (int i = 0; i < 15; i++)
{

dr["Title"] = "第" + i + "條數據";
dr["Author"] = "user00" + i;

dt.Rows.Add(dr);
}

}
//操作上一頁下一頁的table
public DataTable GetPagedTable(DataTable dt, int PageIndex, int PageSize)
{

newdt.Clear();
int rowbegin = (PageIndex - 1) * PageSize;
int rowend = PageIndex * PageSize;
if (rowbegin >= dt.Rows.Count)
return newdt;
if (rowend > dt.Rows.Count)
rowend = dt.Rows.Count;
for (int i = rowbegin; i <= rowend - 1; i++)
{
DataRow newdr = newdt.NewRow();
DataRow dr = dt.Rows[i];
foreach (DataColumn column in dt.Columns)
{
newdr[column.ColumnName] = dr[column.ColumnName];
}
newdt.Rows.Add(newdr);
}
return newdt;
}
}
}
後臺頁面的dataTable中數據是我自己模擬的數據，也可以從數據庫中查詢出來放到dataTable中，然後再對datatable進行操作！
