Client Side validation:
A Javascript function can be written to disable/enable the
text box and it can be called under
DrowpDownList_SelectIndexChanged event. We can provide an
if condition and get the required change in javascript
function.
or else
Server side validation:
we can make the dropdownlist 'AutoPostBack' property true.
and under the DrowpDownList_SelectIndexChanged event, we
can disable/enable the textbox.
