relate asp.net datalist in one page

use linkButton instead of hyper link and on click event bind datalist2

As vinayak said use a LinkButton instead Hyperlink

If you want to populate second datalist based on one datalist you can do as following

1. In first datalist Add command argument to the LinkButton and set the column value on which basis you want to filter

2. Then on click event get the value from command argument and populate the second datalist

thanks  alot it did it 

this is my code

 protected void LinkButton1_Click(object sender, EventArgs e)
    {
        string code = (sender as LinkButton).CommandArgument;
        SqlCommand _cmd = new SqlCommand("showoffer", _cn);
        _cmd.CommandType = CommandType.StoredProcedure;
        _cmd.Parameters.AddWithValue("@Model", code);
        _cn.Open();
        SqlDataReader _dr = _cmd.ExecuteReader();
        if (_dr.HasRows)
        {
            DataList1.DataSource = _dr;
            DataList1.DataBind();


        }
        _cn.Close();

    }

select Description,Name,Model,Garranty,Country,image,image1,image2
