In jquery script i have used Main_Content word with every controls ID, Actually When I am using controls in side the content placeholder at run time every controls id will be concatinated  with this word.

This is the page load even of code behind which is just binding my grid, customize it acordingly-
protected void Page_Load(object sender, EventArgs e)
{ if (!IsPostBack)
{ string connectionString = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
DataTable dt = new DataTable();
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand("Select * from Albums;", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
Label1.Text = "Record(s) " + dt.Rows.Count + " found.";
}
}
