Hi, Try this

Create a table :
create table student(name varchar(30), class varchar(10))

Html Code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!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>

</div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:DropDownList ID="DropDownList1" runat="server" Height="16px" Width="97px">
<asp:ListItem Selected="True">Sem-I</asp:ListItem>
<asp:ListItem>Sem-II</asp:ListItem>
</asp:DropDownList>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
</ContentTemplate>
</asp:UpdatePanel>
<p>
&nbsp;</p>

</form>
</body>
</html>


C# Code-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page

{

}
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=mydatabase;Integrated Security=True;");
con.Open();
SqlCommand cmd = new SqlCommand("insert student values('" + TextBox1.Text + "','" + DropDownList1.SelectedItem.ToString() + "')", con);
