Answer 1

List<Errorlog> lst = new List<Errorlog>(); // create list 
// loop and add items to above list as below 
foreach (int k in id) 
{ 
    DynamicParameters param = new DynamicParameters(); 
    param.Add("SiteId",k, DbType.Int16); 
    List<Errorlog> temp= con.Query<Errorlog>("Usp_Temp", param, null, true, 200, CommandType.StoredProcedure).ToList(); 
    //add to main list 
    lst .AddRange(temp); 

} 
//finally show all the data 
if (lst.Count != 0) 
{ 
    grd.DataSource = lst; 
    grd.DataBind(); 
}
