New Post: Javascript error on page load

Encosia — Sat, 02 Jul 2011 02:01:55 GMT

I'm not able to reproduce that issue when running the included sample site in FireFox 4.

Can you provide a sample page/project that reproduces the error you're seeing and let me know which specific version of FireFox?

Thanks for the control..

Did you able to add the Empty string validation??

New Post: Disabling WebService documentation causes UAV errors.

aturlov — Thu, 12 Mar 2009 14:52:08 GMT

When you perform a postback the server-side validation method is called which relies on the WSDL information being exposed by a Web service to generate a WS proxy on the fly. By disabling documentation on your WS you have prevented the validator from calling the WS hense the error.

If you disable the WSDL on your WS you can only use the client-side functionality of the UAV.

GrZeCh — Tue, 04 Nov 2008 15:01:15 GMT

Hello!

I've disabled documentation in web.config by using:

        <webServices>
           <protocols>
               <remove name="Documentation"/>
           </protocols>
       </webServices>

and UAV started to crash during postback. Can You check this?

Thanks in advance

P.S. Errors was in line 104 (return IsUsernameAvailable(controlValidationValue);) and 117 (Stream stream = client.OpenRead(uri););

New Post: Regarding Samples

Encosia — Sun, 28 Sep 2008 16:17:01 GMT

I'd definitely like to see an example that uses the MembershipProvider and one that shows an example of looking up the username in an arbitrary "users" table, so that the flexibility of the control is clear. Using the MembershipProvider is ideal, but the proprietary use case will probably be most common.

New Post: Regarding Samples

mosessaur — Sun, 28 Sep 2008 01:08:48 GMT

Shall we provide different sample scenarios?! Like for example using PageMethods. Also providing sample Database that is based on ASP.NET Membership and to provide some practical demo just like the one I presented in my post Username Availability Validator almost ready, the early demo
I should mention that the design presented in the current sample was taken from Matt Berseth post Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels.

New Post: Building Futures Road Map Features Draft

mosessaur — Sat, 27 Sep 2008 14:17:15 GMT

What about building future road map features draft for UAV?
In fact I don't think this would be huge list, The control is specific and serving very specific area! but at least we can come up with few ideas to be scheduled for upcoming releases.
What are supposed to be mentioned in this discussion is just a brain storming and draft, no promises or commitments :o)

New Post: Communication Method

impostal22 — Wed, 24 Sep 2008 22:47:39 GMT

Couldn't we instead create an interface that the IsUsernameAvailable web service AND page.validate call, rather than using reflection to invoke a web service? I feel like the web service should not have any code besides creating an instance of a class and invoking a method. Any thoughts?

We can create an issue targeted at release "1.0" for this.

Can we create an issue that won't be resolved until we're all done??

For one-off minification, I often find myself at this page: http://fmarcia.info/jsmin/test.html

JRumerman — Tue, 23 Sep 2008 03:45:14 GMT

So assuming we supply the two scripts, the ASP.NET AJAX framework can handle switching between a release and debug version of the scripts automatically.

Using a ScriptReference, we supply the name of the release version of the script. Using MSFT naming conventions, it would be UsernameAvailabilityValidator.js. Then we also provide a debug version of the script, UsernameAvailabilityValidator.debug.js. The ScriptReference points to the release version of the script.

Then, when the ScriptManager's ScriptMode is set to auto, which it is by default, it will use the IsDebuggingEnabled flag, which is populated by the web.config compilation node, to determine which file to load from the assembly. We can force the ScriptManager to use a particular ScriptMode by setting the property to release, debug, or inherit or by setting the ScriptMode property on the ScriptReference.

This is how MSFT automatically switches between the release and debug version of their AJAX Library.

More information about this capability can be found here: ScriptMode.

I totally agree with this step as it makes the control look like a professional product. It would be nice if MSFT provided some automatic build step to minify and create the release version, but I don't think they're quite there yet. I would recommend doing this as a final build step as modifying the minified file as you go can be a real pain in the ass.

New Post: Validate for Empty String with different error message!

Encosia — Tue, 23 Sep 2008 00:18:14 GMT

Assuming we're in agreement about validating for minimum length, what should be property name be for its validation message?

MinimumLengthErrorMessage? That's kind of long.

UsernameLengthErrorMessage? Ugh, getting longer...

Any ideas that will be discoverable, but aren't ridiculously long?

New Post: How should we CSS style the messages?

vbtwo31984 — Mon, 22 Sep 2008 22:54:51 GMT

I think we should have just a CssClass property that would apply to everything and then a SuccessCssClass/FailureCssClass for custom styling when success/failure needs to be different (the first way). CssClass is pretty standard property on .NET controls, so we should follow the naming conventions.

New Post: Client-side caching?

Encosia — Mon, 22 Sep 2008 22:54:19 GMT

I think it could be beneficial. It came up a bit near the end of this thread.

Like Joel mentioned, an important concern would be avoiding cached false positives due to a period of user inactivity. Maybe if we included a lookup timestamp with the cached username, and only reused cached lookups within a ~60 second window?

New Post: How should we CSS style the messages?

Encosia — Mon, 22 Sep 2008 22:48:03 GMT

Yes, it should definitely allow the developer to specify the class if desired.

I'd like to also aim for some useful defaults too, so configuration is as optional as possible.

New Post: Client-side caching?

jnagy — Mon, 22 Sep 2008 22:43:13 GMT

What is your opinion about implementing client-side cache, something like that AutoComplete control uses?
In some cases using client-side cache we can avoid multiple validation of same username.

New Post: JavaScript Compression

Encosia — Mon, 22 Sep 2008 22:40:30 GMT

That's definitely a good idea.

In one of my controls, I use this code to conditionally output the correct script:

// Register the JavaScript class include.
if (HttpContext.Current.IsDebuggingEnabled)
Page.ClientScript.RegisterClientScriptResource(GetType(), "PostBackRitalin.PostBackRitalin.js");
else
Page.ClientScript.RegisterClientScriptResource(GetType(), "PostBackRitalin.PostBackRitalin.min.js");

I haven't tested it extensively, but it appeared to work as intended without requiring any configuration on the user's end. Maybe it would work for us as well.
