Step 3: Open SQL Server 2008, Connect it by servername and username and password, You can also connect your sql server by window authentication service without using username and password.

Step 4: Click on new query and create database. You can create database using command and manual option in sql server. Here I create a database named ‘Test_Demo’. Check the query given below:

create database Test_Demo
use Test_Demo

After create database you must execute query ‘use Test_Demo’.

Step 5: Now i can create a table which holds my records. I create a table named ‘Employee’ having four columns e.g empid, name, city and age. Command is given for create table below.

create table Employee
(
empid int primary key identity,
name varchar(50),
city varchar(50),
age int
)

Step 6: Now we code in web form, we have two pages like aspx and cs page, Aspx page regarding the design page and cs page for c-sharp code. Here we have three textbox control of asp.net and on button for saving records.

Code: 

Employe.aspx

<form id=”form1″ runat=”server”>
    <div>
   Name : <asp:TextBox ID=”txtname” runat=”server”></asp:TextBox>
   City : <asp:TextBox ID=”txtcity” runat=”server”></asp:TextBox>
    Age : <asp:TextBox ID=”txtage” runat=”server”></asp:TextBox>
        <asp:Button ID=”btnsubmit” runat=”server” Text=”Save” OnClick=”btnsubmit_Click” />
    </div>
    </form>

Place this code under head tag of aspx page.

Employe.aspx.cs:

namespace Test11918
{
    public partial class Employee : System.Web.UI.Page
    {
        SqlConnection con = new SqlConnection(“data source=(server_name);initial catalog=Test_Demo;integrated security=true”);
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void btnsubmit_Click(object sender, EventArgs e)
        {
            con.Open();
            SqlCommand cmd = new SqlCommand(“insert into Employee(name,city,age)values(‘”+txtname.Text+”‘,'”+txtcity.Text+”‘,'”+txtage.Text+”‘)”,con);
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
}

Put this code under head tag of aspx.cs page.
