Combobox column in datagridview having thousands of records takes time to display

[Hardy123]

Hi,
I am having a combobox column in a datagridview named "dgcProfessor" which contains the list of professors names.
i am filling that column with a datatable
Now that datatable have more than 10000 records in it
so now when i want to select a professor from that list
I click on the dropdown arrow of the combobox column but
the dropdown list takes some time to display the list of professors on the screen, so it is not displaying in speedy manner

is there any solution to display it in speedy manner
what should i do to display dropdown list in fast manner

That's expected due to having 10K records. You might want to sort the people into departments and then go from there.
