Make the function have a return statement.

function DoThings() {
   var txt = txtbox.value;
   txt = /* passed info from code behind */
   return txt; //return it.
}

$(function() { 
    var Tags=[DoThings()]; $("#txtbox2").autocomplete({source: Tags});});

what does those '[]' surrounding DoThings() do?

Odds are that any autocomplete function is going to be ajaxy stuff and, being asynchronous, won't let you return anything.

@Quentin That's true, in ajax way, an callback function should be provide.

sorry, ive tried to update my method. i was hoping to avoid posting the whole thing and just grab a quick answer. but as ive said, i cant call the method from inside the jquery as i need to call it after keyup **note, if you have a pre built string, calling the method inside the juqery array works a treat

Sorry for the confusing edit updates - @user1168783 you should possibly update your question with the updated methods, or as xdazz suggests provide a jsfiddle sample you can both work on.
