converting asp:textbox to uppercase

[Ruby]

hi...
how can I convert user's input in textbox to uppercase, I try to write
client-side javascript (onkeypress event), and registered with
registeredstartupscript, it worked but there's a delay time everytime I
pressed a key.
Is there's any suggestion

Hi Ruby,

Try using the textbox's onchange event, instead. Then it will fire when you
change the contents of the textbox AND it loses focus.
