Filtering Combobox choices

Filtering Combobox choices

I have a data grid containing
Client Name Account Type Date Created
I also have 3 comboboxes which when an item is clicked it calls the
SelectedIndexChanged
function which is then reflected in the data grid by moving to a matching
occurance . However multiple clients can have the same account type so I
want my combobox to work so that if an account type is clicked it calls
the selectedIndexChanged function such that it moves to a row where the
account type is correct but the Client name is also contained in that row
