“GridView1”上同时定义了 DataSource 和 DataSourceID。请移除一个定义我是一个初学者，下面这段代码是为了实现查询功能，我用了数据源，不知道为什么冲突了... Partial Class index Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then Call binddata() '绑定数据 End If End Sub Sub binddata2(ByVal sql As String) Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\1018me\App_Data\1018data.mdb") Dim cmd As New OleDbCommand(sql, conn) Dim adp As New OleDbDataAdapter(cmd) Dim ds As New DataSet adp.Fill(ds, "客户数据库") GridView1.DataSource = ds.Tables("客户数据库").DefaultView GridView1.DataBind() conn.Close() End Sub Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sql As String If TextBox1.Text = "" Then sql = "select 公司名称,经营品牌,项目名称,经营范围,经营方式,联系人,电话,传真 from 客户数据库" Else sql = "select 公司名称,经营品牌,项目名称,经营范围,经营方式,联系人,电话,传真 from 客户数据库 where 公司名称 like '%" & Trim(TextBox1.Text) & "%'" End If Call binddata2(sql) GridView1.Visible = True 'TextBox1.Text = "" End Sub Sub binddata() Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\1018me\App_Data\1018data.mdb") conn.Open() 'Dim sql As String 'sql = "select 公司名称,经营品牌,项目名称,经营范围,经营方式,联系人,电话,传真 from 客户数据库" 'Dim cmd As New OleDbCommand(sql, conn) 'Dim adp As New OleDbDataAdapter(cmd) 'Dim ds As New DataSet 'adp.Fill(ds, "客户数据库") 'GridView1.DataSource = ds.Tables("客户数据库").DefaultView GridView1.DataBind() conn.Close() End Sub Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridView1.PageIndexChanging GridView1.PageIndex = e.NewPageIndex '设置要显示的新页 Call binddata() End Sub End Class
