In my code I want to add combobox to "Datagridview" results, I have already find solutions how to add combobox or checkbox for datagridview but with ADDING NEW COLUMN, I want to add the checkbox to existing result, I'll explain to you in details,

If I have a results for "Select query" to show data, I don't want to add new column at last or first, i want to put the combobox at existing column (which is coming from database) , to modify its result and update the existing records at the database for same column.

For example, if i get database of student attendance, so i will have student name column and attendance column, i want to change the status of student to be absence instead of available through combobox that generated at datagrid result loading !!
