Simulating a button-click after user types in textbox & hits "enter"

[KingRichard3]

I have many dynamically generated textbox/command button pairs on a page. How can I set the button to act as if it was clicked after the user types in a value in its corresponding textbox and then hits the "enter" key?

Thanks,
Rick

P.S. I know the following exists for a page (and can be inserted into Page_Load:

Page.RegisterHiddenField("__EVENTTARGET", "cmdSubmit") 'where "cmdSubmit" is a string with the name of the default button

But does anything like that exist for an individual control?

Thanks again,
Rick
