You can add SelectedIndexChanged event to both dropdownlist controls and check the dropdownlist1 and dropdownlist selected items values, if both dropdownlists having values, you can load data.

there is two option first select two dropdown and click at a button

or selectedindexchange event as DamithsL said

the easy way is to use a button because it is not complicate for beginer programmer

but you can try to use selectedindexchange event to learn how to add event and how to use the event for

another event control for the future

Cheer

string SelectedIndex = "";

SelectedIndex = combobox.selecteditem ;
