Question

How Create Data Table From Top 5 or 6 row in datagridview including column header also .

Answer 1

your explanation is too short. Any how, what i understand from this is that either you have a datable and you want to bind its just top 5 to 6 rows to data grid or u want to bring your data grid row to datatable with headers both can done through for each loop..

You can get column names like this from data

string columnName = mydatagrid.Columns[columnIndex].Name;

OR you can get both rows and column using foreach loop

 foreach(DataGridColumn col in dg.Columns)
   {
     dt.columns.Add(col.HeaderText);
   }

 foreach(DataGridRow in dg.Rows)
 {
  if(dt.Rows.Count < 6)
  //Add data to data table

 }

The same way you can apply with little modifications to get data from datatable
