Of course, I could be wrong, but from the context of the question I realized that we are talking about a group of university students.
If this is the case, then you can organize all this within one table by adding one more column: Group number. Next, make a selection from the table - get a list of all possible groups (SELECT DISTINCT ... ) and add it to the ComboBox (the Add (...) method, as far as I remember). On the SelectedIndexChanged event , make a selection from the same table by adding the condition that the group number is equal to the selected value in the ComboBox and add the result of the selection to the table (GridView).
