Hi,
please add the follwoing code in you aspx.cs page.

Step 1 : Add Namspace "using System.Data.SqlClient;"

Step 2 : Make Sql connection.

Write this code to create Sql connection.
SqlConnection con = new SqlConnection("Server=You server name or comp name;Database=Yourdatabasename;Trusted_Connectopn=True");
SqlCommand cmd = new SqlCommand("Write your sql query here eg. select * from Table name");
con.Open();
DataSet ds = new DataSet(cmd,con);
SqlDataAdapter da = new SqlDataAdapter();
da.Fill(ds);
con.Close();

i hope this should work

1: Open visual studio 2005 and from FILE select NEW-> WebSite, then from pop-menu select asp.net
website (Note: Language must be C#) , then press OK.

2: Now create three textboxes from the toolbox , to remove ambiguity I am using default name for that textboxes and that should be textbox1,textbox2 & textbox3. And also drag & drop the button to the asp.net application.

3: Meanwhile, Open SQL SERVER Management studio 2005 and open adventureworks(or you can create your own database by the Sql command CREATE DATABASE database_name), but here I am using AdventureWorks database.

4: Then create table by clicking right mouse button and form three column, Name them according to your requirement , for your information only I used EID,name,Address. And click save button, then you’ll get a pop up menu where you have to enter the Table Name, for this example I used students.

5: Now Come Back to Visual studio Application and write the following code in the button_click event.

protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection myConn = new SqlConnection();
myConn.ConnectionString = “Connection string(See Below for this — )COPY PASTE  HERE“;

myConn.Open();
string strqry = “Insert into students values (” + TextBox1.Text +
“,’” + TextBox2.Text + “‘,’” + TextBox3.Text + “‘)”;

SqlCommand myCom = new SqlCommand(strqry, myConn);
int numrow = myCom.ExecuteNonQuery();
myConn.Close();

}
