Hello Folks,
Am having a little confusion.
I have an external javascript file in my project under the Scripts folder named as Hierarchy.js...
This external jscript file contains some 3-4 different functions with one being KeySelected.
Now I need to call this very function in the OnClientItemSelected property of an AJAX autocomplete extender in a user control inside the folder named as User Controls.
Will this work :

OnClientItemSelected="KeySelected"

Or do i need to write the whole path?
Also, a thing to note, folders Scripts and User Controls are in the same project.

Suggestions and assistances are highly appreciated.
