Solution 1

try

for (int i = 0; i < dt.Rows.Count; i++)
            {
                DataRow myrow = dt.Rows[i];
                list.Add( string.Format("'{0}'" , myrow["empid"].ToString()));
            }
            //
            string filter = string.Join(",", list);
            
            dvData.RowFilter = "empid in (" + filter + ")";

Hi karthik, i guess filter should be like this,

string filter = string.Join(",", list.Select(r=> "'"+ r + "'"));

that is taken care here
list.Add( string.Format("'{0}'" , myrow["empid"].ToString()));
