Enable a button when all three text boxes are filled data

[aspfun via DotNetMonster.com]

In a web page, there are three text boxes and one button (enable=false).

When page load, I used javascrip to paste some info to fill out three text
boxes from clipboard in which another program will copy to.

How to code to make the button enable = true only when all thee text boxes
are filled?

I tried to add code below at end of page_load but do not work.

if textbox1.text <> "" and textbox2.text <> "" and textbox3.text <> "" then
button1.enable = true

First of all, do you want to do this check client or server side? It sounds
like something that you would want to do client-side using JavaScript. If
you do it server-side in the Load event, the values of the TextBoxes' Text
properties must be set before doing the check, and the Button's status will
not change once the Page is rendered (unless you have something other
client-side code that changes the Button's status). Please clarify exactly
what you want.

create method/function seperatly i call it "ckFields()"

Private Sub ckFields()

if textbox1.text <> "" and textbox2.text <> "" and textbox3.text <> "" then

Button1.Enabled = True
Else
Button1.Enabled = False
End If
End Sub

'Set AutoPostBack="true" for all textboxes
'now call method/function on EVERY textBox's Text change Event

Protected Sub textbox1_TextChanged(ByVal...)
ckFields()
End Sub
