Why is a button Click event also called when a textbox TextChanged event is called???

[S_K]

This is a weird problem..

I have a page with a textbox and a button (along with a bunch of other
stuff). Both the textbox and the button have their SEPERATE events
defined for the textchanged and click events. When I change the text
in the textbox the textchanged event is called as expected. But the
button click event is also called!?

Whats with that?!

Can anybody help? This is driving me crazy!

Thanks

Steve

possible reasons

1) you hit enter/return after changing the text. this will cause the
button to postback

2) you don't have autopostback set on the textbox, so the postback only
occurs when you hit the button.

First, Thanks for responding.

Second, The first possiblility makes sense. However, why would hitting
the <ENT> or return key cause a button event to fire? Is there any way
I can undo that?

Thanks again.

if ((evt.keyCode == 13) && (node.type=="text")) {return false;}
}

If you are using .NET 2.0, you can set the Button's UseSubmmitBehavior
property to false.
