Problem on submit button

[Kathy Burke]

Justin,

As I posted earlier today, I have this same problem. UNLESS I put a
button on the page, my textchanged autopostback won't fire on ENTER
(will sometimes fire on TAB).

I have one textbox, no buttons, the textbox won't fire alone. Would you
have similar code to fix this? Right now, I've had to put a tiny button
on my page that does nothing but sit there to allow the textbox to be
functional. THIS JUST DOESN'T SEEM RIGHT. If I make the button
visible=false, the textbox no longer works.

IS THIS A BUG? Because the textbox set to autopostback=true does NOT
function as advertised.

Thanks.

Kathy

Sorry, just one more thing...since no one has answered my previous post
on this one.

On another page, I have an asp:textbox and an asp:button. The button
runs javascript to open a pop-up window. The textbox is supposed to run
textchanged sub when ENTER is pressed.

What happens is that the textbox event does fire, but so does the button
event EVERY TIME.

Any suggestions for correcting this?

Thanks again.

The TextBox's "TextChanged" event isn't supposed to fire when the value in
it changes on the client. From the .Net SDK:

"Occurs when the content of the text box changes between posts to the
server."

This means that when the Page posts back, if the content of the textbox has
changed, this event will fire.

The client-side "onchange" event for a textbox fires whenever the value
changes in the textbox, and you don't want it to PostBack whenever THAT
happens. For example, on the client, if you were to type the string "Hello"
into a textbox, the "onchange" event would fire 5 times!

Kathy,

The button is fired because it is the only one on the form. (I know you
already know this because you said you added a button to keep this from
happening.) This is not a .net behaviour. This is the way browsers are
designed. If a form only has one submit button in it the browser assumes
it's the default button and should be clicked when enter is pressed from
anywhere in the form.

The solution might depend on what you are doing with the button. If the
button isn't triggering an event server side you may be able to just switch
to an html button. Use a button set to type="button" instead of
type="submit" and it won't post back automatically on enter. You could even
use a javascript with form.submit() in it and the button would still post
back to the server if you need to submit the form.

But if you are running a server side event based on the button's submit then
you need to use some type .net control. Maybe you could use a link button
instead of a regular button. It wouldn't be exactly the same look, but a
link that says submit will still be pretty clear to the users. (A link
button wouldn't submit when enter is pressed from the text box.)

I hope one of these options solves your problem! :)

Thanks again, Justin, that IS making it a bit clearer.

I have a page WITHOUT a submit button, just a textbox. From the SDK doc,
my understanding is that if you create an asp:textbox control WITH
AutoPostBack = True, then on ENTER it should do the _DOPOSTBACK from the
html code (I DO see this in the html source.

But without that button somewhere on the page, the _DOPOSTBACK on the
ENTER event doesn't fire.

Am I just being stupid? You're explanation was great, just still
wondering how to move forward.

On the page where I have the same textbox but I DO have a button that
runs a javascript popup window, every time I hit ENTER (aka Submit) it
also opens up the popup window from the button. Any suggestions on how
to stop that?

Again, really appreciate your time.

Kathy,

Now I understand what you're trying to do!

I took a look at the documentation and here's an exact quote about the
autopostback of a text box: "Gets or sets a value indicating whether an
automatic postback to the server will occur whenever the user modifies the
text in the TextBox control and then tabs out of the control."

Notice that it says: "...and then tabs..."

But now I'm really confused becuase I just created a blank web form with a
single text box on it and sure enough when I tab out of the control the form
posts back to the server. And it posts back when I hit the enter key also!

So now I don't know why yours doesn't.

I'm using v1.1 of the .net framework and Visual Studio.Net 2003 are you
using the same?

Kathy,

I think you need to solve the text box post back problem. If you do I think
that then solves both of your problems. As I've discovered my text box does
an auto post back just like it's supposed to and it does so without any
button on the page.

If you solve that then you'll be able to use a different type of button on
your form where you are opening a new window and both problems will be
solved.

Could you post your code? If I had your code to test perhaps I could
discover what's wrong.

Justin, you're right, if I (aka "we"?) could solve this it would make my
life much easier going forward.

Thank you for all the help...Kathy

Here is my aspx.vb code. It is the page where I have a textbox with
TextChanged event that I need to run on ENTER and a button to open a
popup window (which currently fires every time ENTER is pressed in the
textbox...I've included the html at the end.

Kathy,

Thanks for posting the code. That helped a lot.

First of all the reason the button that opens the popup window is still
causing a post back is pretty simple. You just have to change the attribute
you're adding from:

btnList.Attributes.Add("onclick", "pop_window();return false;")

to:

btnList.Attributes.Add("onclick", "javascript:pop_window();return false;")

Now it doesn't post back when clicked, but it creates another problem. Now
the text box doesn't post back.

But I've solved that also.

The text box's autopostback works as advertised. It will post back if the
text inside it is changed from whatever it was when the form was entered and
then it's tabbed out of. (I know this isn't what you desire. Here are two
choices:

1) If you want the text box to submit the form when the enter key is pressed
no matter whether the text in it was changed or not then:

Set it's autopostback attribute to False

and use this exact code:

txtScan.Attributes.Add("onkeydown", "javascript:if((event.which &&
event.which == 13) || (event.keyCode && event.keyCode ==
13)){form.submit();return false;}else return true;")

(It won't post back when tabbed this way though.)

You'll note that this code is just submitting the form. You'll probably
have to examine the
text box each time in the page load event to see what text is in it
because the text
changed event won't fire this way.

2) If you still want the text box to submit when tabbed and only if the text
has been changed then:

Set it's autopostback attribute to True

and use this exact code:

txtScan.Attributes.Add("onkeydown", "javascript:if((event.which &&
event.which == 13) || (event.keyCode && event.keyCode ==
13)){__doPostBack('txtScan','');return false;}else return true;")

This way you could still use the text changed event in your codebehind
page.
