Question

我正在进行一项任务，我必须使用VB.net和Access数据库才能建立书店。其中一个要求是我必须制作一个包含书名和客户名称的表格，并在标题和客户名称上添加超链接，将其重定向到新页面。我有表工作，但我无法添加超链接到表中的一个列。还有一个搜索功能，我必须打印价格范围之间的所有书籍（例如20美元<价格<= 30美元）我有单选按钮设置，但我无法进行实际搜索并获得良好的价值。我的代码如下：

Imports System
Imports System.Data
Imports System.Data.OleDb
Imports System.Data.SqlClient

Public Class CustomerSearching
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        RadioButton1.Visible = False
        RadioButton2.Visible = False
        RadioButton3.Visible = False
        RadioButton4.Visible = False
        RadioButton5.Visible = False
    End Sub

    Protected Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        Dim conn As New OleDb.OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" + Server.MapPath("~/bookstore.accdb"))
        conn.Open()

    End Sub

    Protected Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
        Response.Redirect("Customer.aspx")
    End Sub

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OleDb.12.0;Data Source=" + Server.MapPath("~/bookstore.accdb"))
        RadioButton1.Visible = True
        RadioButton2.Visible = True
        RadioButton3.Visible = True
        RadioButton4.Visible = True
        RadioButton5.Visible = True

        If (RadioButton1.Checked) Then
            conn.Open()
            Dim sql As String = "SELECT * FROM books WHERE price < $10.00"
            Dim dbcomm As New OleDb.OleDbCommand(sql, conn)
            Dim dbread = dbcomm.ExecuteReader()
            bookSearching.DataSource = dbread
            bookSearching.DataBind()
            dbread.Close()
            conn.Close()
        End If

    End Sub

    Protected Sub RadioButton1_CheckedChanged(sender As Object, e As EventArgs) Handles RadioButton1.CheckedChanged

    End Sub
End Class

对于超链接，我使用vb选项来设计和拖动sqlDataSource和gridview，并将两者与我的bookstore.accdb文件链接在一起。非常感谢您的帮助。非常感谢。
