Question

我想在datagirdview中包含两行的数据，使用我的列已显示的代码，但是数据，我的意思是该行中没有数据。这是我的代码

  Dim sqlcon As New SqlConnection("Data Source=ALLAYE\SQLEXPRESS;Initial Catalog=Business;Integrated Security=True")
        Dim sqlcmd As New SqlCommand("SELECT OrderTB.OrderID, OrderTB.CustomerID, OrderTB.OrderDate, OrderTB.TotalOrder, CustomerTB.CustomerID AS CusID, CustomerTB.CompanyName, CustomerTB.CustomerPhone
FROM     OrderTB INNER JOIN
                  CustomerTB ON OrderTB.CustomerID = CustomerTB.CustomerID", sqlcon)
        sqlcon.Open()
        Dim sqladp As New SqlDataAdapter(sqlcmd)
        Dim dt As New DataTable
        sqladp.Fill(dt)
        DataGridView1.DataSource = dt.TableName
        sqlcon.Close()

尝试一下。

Imports System.Data.SqlClient
Public Class Form1
    Dim connetionString As String
    Dim connection As SqlConnection
    Dim adapter As SqlDataAdapter
    Dim cmdBuilder As SqlCommandBuilder
    Dim ds As New DataSet
    Dim changes As DataSet
    Dim sql As String
    Dim i As Int32

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
        connection = New SqlConnection(connetionString)
        Sql = "select * from Product"
        Try
            connection.Open()
            adapter = New SqlDataAdapter(Sql, connection)
            adapter.Fill(ds)
            connection.Close()
            DataGridView1.Data Source= ds.Tables(0)
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub

End Class

datagridview仅在列中不包含数据库中的数据
