Are you trying to find the server-side control ID, as opposed to the
"munged" client-side control ID...?

Re: javascript string manipulation

use
DrpX.ClientID
or sometimes
DrpX.UniqueID

depending on what you need name or id of the control...

Re: javascript string manipulation

can you use this if the textbox resides in a WebUserControl which in turn is
on the .aspx page?

i tried document.getElementById('<% WebUserControl1_TextBox1 %'>)
but it won't compile, it says TextBox1 doesn't exist in this context.

Firstly, you need the = sign, which is ASP.NET shorthand for Response.Write

Secondly, you need to specify the .ClientID property of the control whose
munged name you want to return...
