此博客展示了ASP.NET中DataGrid和RadioButton的使用。通过C#代码，实现了DataGrid的数据源绑定，以及利用RadioButton控制DataGrid列和整体的可见性，包含了页面加载、RadioButton点击事件处理等功能。

<%@ Page Language="C#" AutoEventWireup="True" Debug="true" %>
<Script language="C#" runat="server">
void Page_Load(Object Sender,EventArgs e){
if (!Page.IsPostBack){
Radio_1.Checked=true;
}
Hashtable HT=new Hashtable();
HT.Add("1234","Microsoft");
HT.Add("5678","IBM");
HT.Add("7895","SUN");
HT.Add("0123","Orlce");

MyDataGrid.DataSource=HT;
MyDataGrid.DataBind();
}

void RadioClick_2(Object Sender,EventArgs E){
MyDataGrid.Columns[2].Visible=false;
Radio_1.Checked=false;
}

void RadioClick_1(Object Sender,EventArgs E){
MyDataGrid.Columns[2].Visible=true;
Radio_2.Checked=false;
}

void RadioClick_3(Object Sender,EventArgs E){
MyDataGrid.Visible=true;
Radio_4.Checked=false;
}

void RadioClick_4(Object Sender,EventArgs E){
MyDataGrid.Visible=false;
Radio_3.Checked=false;
}
