ASP.NET查询ACCESS数据库的内容并在DATAVIEW中显示出来
论坛链接
在http://blog.csdn.net/axjuan/archive/2007/02/25/1514344.aspx 这篇文章中，就可以在DATAVIEW中显示记录了，但是如果你的字段名是英文或者你想设置一下DATAVIEW的样式，使其更美观，就不能使用这么简单的代码显示了。
首先，如果要把标题显示为汉字，那么需要设置DATAVIEW的AutoGenerateColumns="false"，不使用默认字段名，然后再设置asp:BoundField的HeaderText属性，来改变列标题；另外可以设置HeaderStyle中的BackColor、Font-Size、HorizontalAlign等属性，使其变得更加美观。下面给一个我自己做的例子：
<%@ Page Language="VB" Debug ="true" %>
<%@ Import Namespace="System.Data.OleDb" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Dim connstr As String
Dim sql As String
Dim mycommand As OleDbCommand
Dim myread As OleDbDataReader
Dim conn As OleDbConnection
Sub page_load(ByVal sender As Object, ByVal e As EventArgs)
connstr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("rizhi.mdb") & ";User Id=;Password=;"
conn = New OleDbConnection(connstr)
conn.Open()
sql = "select * from rizhi"
mycommand = New OleDbCommand(sql, conn)
myread = mycommand.ExecuteReader()
GridView1.DataSource = myread
GridView1.DataBind()
'Dim i As Integer
'Do While myread.Read()
' i = i + 1
'Loop
'Response.Write(i)
End Sub
</script>

值得注意的是，这里不光显示了数据，而且还有一列是对数据的“操作”，当用户点击该列的时候，转到修改页面，并传递一个参数id，这里传递参数的方法是 DataNavigateUrlFormatString="<% rizhi_edit.aspx?id={0} %>" ，其中0表示第一个字段，1表示第二个字段，依此类推。
