After completion of aspx page design add following namespaces in code behind

C# Code

using System;
using System.Data;
using System.Data.SqlClient;
After add namespace write the following code


private SqlConnection con = new SqlConnection("Data Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true");
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindRepeaterData();
}
}
// This button click event is used to insert comment details and bind data to repeater control
protected void btnSubmit_Click(object sender, EventArgs e)
{
con.Open();
SqlCommand cmd = new SqlCommand("insert into Repeater_Table (UserName,Subject,Comment,PostedDate) values(@userName,@subject,@comment,@postedDate)", con);
cmd.Parameters.AddWithValue("@userName", txtName.Text);
cmd.Parameters.AddWithValue("@subject", txtSubject.Text);
cmd.Parameters.AddWithValue("@comment", txtComment.Text);
cmd.Parameters.AddWithValue("@postedDate", DateTime.Now);
cmd.ExecuteNonQuery();
con.Close();
txtName.Text = string.Empty;
txtSubject.Text = string.Empty;
txtComment.Text = string.Empty;
BindRepeaterData();
}
//Bind Data to Repeater Control
protected void BindRepeaterData()
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from Repeater_Table Order By PostedDate desc", con);
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
RepDetails.DataSource = ds;
RepDetails.DataBind();
con.Close();
}
