这是我的vb代码：

Imports System.Data.SqlClient
Imports System.Data

Partial Class testt
    Inherits System.Web.UI.Page
    Public connectionString As String = ConfigurationManager.ConnectionStrings("TestConnectionString").ConnectionString
    Public cn As SqlConnection = New SqlConnection(connectionString)
    Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        Dim ds As New DataSet
        Dim dt As New DataTable
        If cn.State = ConnectionState.Closed Then
            cn.Open()
        End If
        Dim command As SqlCommand = New SqlCommand("selecttest", cn)
        command.CommandType = CommandType.StoredProcedure
        Dim da As New SqlDataAdapter(command)
        da.Fill(ds, "testtt")
        dt = ds.Tables(0)
        GridView1.DataSource = dt
        If Not IsPostBack Then
            GridView1.DataBind()
        End If
        If cn.State = ConnectionState.Open Then

        Dim strPersonID As String = DirectCast(GridView1.Rows(e.RowIndex).FindControl("TextBox1"), TextBox).Text
        Dim strLastName As String = DirectCast(GridView1.Rows(e.RowIndex).FindControl("TextBox2"), TextBox).Text
        Try

            command.Parameters.AddWithValue("@pid", strPersonID)
            command.Parameters.AddWithValue("@pfirstname", strLastName)

            End If
            command.ExecuteNonQuery()
            MsgBox("1 row updated")
            If cn.State = ConnectionState.Open Then

    End Sub
    Public Sub GridView1_RowEditing(sender As Object, e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
        GridView1.EditIndex = e.NewEditIndex
        If Not IsPostBack Then

1-网格中的列是重复的，这意味着我从存储过程中获取所选数据，并在新列中的模板字段中绑定数据，而不是只获得2列我得到4相同的数据，我该如何解决这个问题？

2 - rowupdating事件中没有错误一切正常但数据库中的数据没有更新。请注意，存储过程在SQL中工作正常。它可能是因为前面提到的重复列...

任何帮助？

谢谢你！

过程不更新数据库中的数据
