#2 Autosuggest Textbox

[jcmurphy]

I am posting an Autosuggest Textbox. This is not done,
but I thought I'd post it now for feedback and
suggestions, as well as to help anyone implementing
something similar. It still as some issues. I'm not
sure it's really "Anthem-y", as it contains a ton of
javascript. There's probably a nicer way to write it.

To use the control, just drop it on a page. The
[Anthem.Method] OnKeyUp has hard coded values in it.
If you type "Ald" in the textbox you can see it in
action. The version I'm actually working on calls a db
proc which returns a ref cursor and builds a string.
If anyone needs that code let me know.

I plan to add support for the following:
1) allow up arrow and down arrow to move through the
dropdown

2)Fix the backspace to suggest

3)Add switches for autosuggest on/off, number of rows
in dd, etc.

It's tested in IE 6 and FF 1.0.7

I'd love to hear criticisms/suggestions

I should also point out that much of the js came from an
article on code project, which I didn't write.

I am uploading a new version of my AutoSuggest Textbox. It
has several new features:
1) Up arrow, down arrow and backspace now work correctly
2) Textbox has attribute AutoSuggest (true/false)
3) Textbox has attribute AllowEditing. If set false, will
not allow user to key text that isn't in the suggest list
4) Textbox has attribute ErrorLabelName. If set to the name
of an Anthem.Label (like Label1), and AllowEditing = False,
will set Label.text to an error message: "You must choose a
value from the dropdown"

Once again, the values are hardcoded in. Type "Ald" to see
it in action. Type "Aldax" to see the AllowEditing
behavior. I have included commented-out code demonstrating
the use with a datareader.

This is tested in IE 6, FF 1.0.7, and Safari 2.

2 more bug fixes. IE wasn't positioning the div correctly
on reflow, and allowediting = false had a race condition
that would allow invalid input

This patch fixes bug 1372311. For anyone using this
control, I've found a possible gotcha using a database.
Make sure you Dispose your DB connections to return them to
the pool, as they will not be GCed quickly enough for long
text entry.

I've uploaded a new version of my autosuggest textbox. It
has the js in a separate file, and includes a test page. I
have only tested it in VS2005 with .Net 2. Hopefully
someone can test in 2003 as well.

I now draw an iframe under the div to prevent IE displaying
windowed controls through the div.

New version implements iupdatable

I've uploaded a new version. It implements Iupdatable. It
also wipes out the text/div on the escape key, and handles
ampersands in the suggested text correctly. I think the
version I sent to the mailing list was the wrong one. I'm
getting confused. Sorry.

i am still working in 1.1 it appears there is a few bugs.
one i fixed the other i cant seem to figure out....

line 135 the stream ref was incorrect needs to be:

Stream stream = typeof
(Anthem.AutoSuggestTextBox).Assembly.GetManifestResourceStre
am("Anthem.TextBox.js");

How do you perform this logic (line 231 in asp.net1.1?)
this.Page.ClientScript.RegisterStartupScript(typeof
(TextBox), newUid, acScript.ToString());

thanks for your help.

Yes, there is an issue with the v1 of the script. Try this:

this.Page.RegisterStartupScript(newUid, acScript.ToString());

I'm testing this in 1.1 and with the change I suggested
below it seems to work just fine.

Yes i could make work the control with this modifications
but i added an #if for the compiler
like this:

#if V2
this.Page.ClientScript.RegisterStartupScript(typeof(TextBox),
newUid, acScript.ToString());
#else
this.Page.RegisterStartupScript(newUid,acScript.ToString());
#endif

Those the same archive (class) works in both versions of .Net :)

Also the line that injects the TextBox.js in VS 2003 must be
changed like is explained below but it's really working?
In my case the page NewAutoSuggest.aspx won't work if you
don't add the
<script language="javascript" type="text/javascript"
src="TextBox.js"></script>

Sorry i pressed "Submit" earlier...

i was saying..

In my case the page NewAutoSuggest.aspx won't work if you
don't add the
<script language="javascript" type="text/javascript"
src="TextBox.js"></script>

In the header of the aspx page and copy the TextBox.js to
the root of the site.

Tks !
