OnTextChange Event

I am trying to have a button enabled when someone starts typing text into an asp:textbox. I tried the OnTextChanged event, but that does not fire until after focus is shifted out of the textbox.

How can I get a button to change from Enabled = false to Enabled = true as soon as someone starts keying text into an asp:textbox?

Thanks for your help.

You will need to use client-side scripting (i.e. javascript)

Assign a keydown event to the textbox and have it disable the button from there.

You may also want to check to see if the textbox is empty to re-enable the button (If that fits into your software model)
