如果 GridView 绑定(bind)在自动生成的表格后面的代码中，我如何在我的 GridView 中只显示两个列？现在它显示六列，而我只想显示两列？
这是我的 .aspx 页面代码:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server">
<columns>
<asp:boundfield datafield="Drug" headertext="ddddrug"/>
<asp:boundfield datafield="date" headertext="ddddate"/>
</columns>
</asp:GridView>
</div>
</form>
</body>
</html>
这是我的代码背后的代码:
Imports System.Data
Partial Class Default2
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' auto generated table
Dim table2 As New DataTable
' Create four typed columns in the DataTable.
table2.Columns.Add("ID", GetType(Integer))
table2.Columns.Add("Drug", GetType(String))
table2.Columns.Add("Patient", GetType(String))
table2.Columns.Add("Date", GetType(DateTime))
' Add five rows with those columns filled in the DataTable.
table2.Rows.Add(25, "Indocin", "David", DateTime.Now)
table2.Rows.Add(50, "Enebrel", "Sam", DateTime.Now)
table2.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now)
table2.Rows.Add(21, "Combivent", "Janet", DateTime.Now)
table2.Rows.Add(1100, "Dilantin", "Melanie", DateTime.Now)
table2.Rows.Add(125, "Indocin", "David", DateTime.Now)
table2.Rows.Add(150, "Enebrel", "Sam", DateTime.Now)
table2.Rows.Add(110, "Hydralazine", "Christoff", DateTime.Now)
GridView1.DataSource = table2
GridView1.DataBind()
End Sub
End Sub
End Class
最佳答案
忽略您拥有的数据多于所需的事实。将 AutoGenerateColumns 设置为 false。为需要显示的列创建 BoundColumns。示例:
BoundColumn nameColumn = new BoundColumn();
nameColumn.DataField = "Drug";
nameColumn.DataFormatString = "{0}";
nameColumn.HeaderText = "Drug";
然后将这个 BoundColumn 添加到 gridview。
GridView1.Columns.Add(nameColumn);
GridView1.AutoGenerateColumns = false;
