Introduction
Introducing a daily use application developed in ASP.NET to manage the contact 
numbers, birthday, email etc. This article will guide using step by step 
approach to create such applications. I am using SQL Server and Access Databases 
separately; any one may be used by the user of this application.
Why I Developed This?
Actually, my mobile phone a huge list of contact and it is very difficult to 
manage on handset always, reason may be anything like data-loose or difficult to 
find on mobile keypad. I exported my entire contact in CSV format and then I 
imported that in Microsoft Access database and then in SQL Server. 
Next, I developed a web application to manage that database having searching, 
shorting, inserting, selecting, editing deleting like features. I would like to 
share the processes here. Find the screen of running application.

AccessDB.aspx Page (Front) Code
I am using show-hide div option to insert new record in database by using some 
javascript codes.

AccessDB.aspx Page Code-Behind
In the code given below I am using quicker code to filter contact and to insert 
new record I am calling a execution() method that has sql query and rest 
mechanism.
public
partial class
_Default : System.Web.UI.Page
{
    protected void 
Button1_Click(object sender,
EventArgs e)
    {
        string FilterExpression =
string.Concat(DropDownList1.SelectedValue,
" LIKE '%{0}%'");
        AccessDataSource1.FilterParameters.Clear();
        AccessDataSource1.FilterParameters.Add(new
ControlParameter(DropDownList1.SelectedValue,
"TextBox1",
"Text"));
        AccessDataSource1.FilterExpression = FilterExpression;
    }
   
protected void 
Button2_Click(object sender,
EventArgs e)
    {
        AccessDataSource1.SelectParameters.Clear();
    }
   
protected void 
btnSubmit_Click(object sender,
EventArgs e)
    {
        execution(Convert.ToString(name.Text),
Convert.ToString(mobile.Text),
Convert.ToString(homenumber.Text),
Convert.ToString(companynumber.Text),
Convert.ToString(email.Text),
Convert.ToString(office.Text),
Convert.ToString(fax.Text),
Convert.ToString(birthday.Text));
        Response.Redirect("~/AccessDB.aspx");
    }
   
private void 
execution(string person_name,
string mobile, 
string home, string company,
string email, 
string office, string fax,
string birthday)
    {
        try
        {
            string connectionString =
"Provider=Microsoft.Jet.OLEDB.4.0;Data 
Source=" + Server.MapPath("App_Data\\ContactsDB.mdb") 
+ ";";
            OleDbConnection conn 
= new 
OleDbConnection(connectionString);
            conn.Open();
            OleDbCommand cmd =
new 
OleDbCommand();
            cmd.Connection = conn;
            cmd.CommandText = "INSERT 
INTO ContactsTB (Person_Name, Mobile, Home, Company, Email, Office, Fax, 
Birthday) VALUES (@person_name, @mobile, @home, @company, @email, @office, @fax, 
@birthday)";
            cmd.Parameters.Add("@person_name",
OleDbType.VarChar).Value = 
person_name;
            cmd.Parameters.Add("@mobile",
OleDbType.VarChar).Value = 
mobile;
            cmd.Parameters.Add("@home",
OleDbType.VarChar).Value = home;
            cmd.Parameters.Add("@company",
OleDbType.VarChar).Value = 
company;
            cmd.Parameters.Add("@email",
OleDbType.VarChar).Value = email;
            cmd.Parameters.Add("@office",
OleDbType.VarChar).Value = 
office;
            cmd.Parameters.Add("@fax",
OleDbType.VarChar).Value = fax;
            cmd.Parameters.Add("@birthday",
OleDbType.VarChar).Value = 
birthday;
            cmd.ExecuteNonQuery();
            conn.Close();
        }
        catch (System.Data.SqlClient.SqlException 
ex_msg)
        {
            string msg =
"Error occured while inserting the 
comment.";
            msg += ex_msg.Message;
            throw 
new Exception(msg);
        }
    }
}
The same process used for SQL Server Database, you can download the attached 
project and take a look at procedures. 
I hope you like it. Please post your comments.
