Of course you can!
I did a very simple but useful demo to proove what I say——
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="TestWebApp.WebForm1" %>
<!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" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<%#Container.DataItem %>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="Select1" TypeName="TestWebApp.Class1"></asp:ObjectDataSource>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
</form>
</body>
</html>
protected void Button1_Click(object sender, EventArgs e)
{
ObjectDataSource1.SelectMethod = "Select2";
}
In Class1——
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace TestWebApp
{
public static class Class1
{
public static string[] Select1()
{
return new string[] { "1","2","4"};
}
public static string[] Select2()
{
return new string[] { "2", "3", "4" };
}
}
}
