hi frnd

you can write you logic as per below code

C#

string proid;
            string querydr = "select * from Products";
            SqlDataReader dr = obj.fillcomb(querydr);
            while (dr.Read())
            {
              if(proid == String.empty)
                  {
                 proid = Convert.ToInt16(dr["ProductID"]);
                 }
              else
                 {
              proid +=","+Convert.ToInt16(dr["ProductID"])
                }
            }

            Response.Redirect("your page name"?ID=proid);

and into another page:

C#

if(Request.QueryString["ID"] !=null && 
Request.QueryString["ID"].toString() != "")
{
 string query = "Select * from Products where ProductID= '" + Request.QueryString["ID"].ToString() + "' AND UnitCost &lt; 5000"; //request.querystring should
}

let me know is this solution is help.

Hi,

defiantly it will show you one record from all your records, reason is Response.Redirect in your button click.

when you click on LinkButton4 it will redirect your page from Response.Redirect line so other code will not execute.

have a look at behavior of Response.Redirect.

you need to change your logic.

hope this will help you to resolving problem,

thanks
