the AjaxControlToolkit has a new release, the release includes bug fixes and new HTMLEditor, ComboBox, ColorPicker controls/extenders.

• Check the release

• Try the live demos

HTML Editor

I liked the HTMLEditor control so much from first sight. Pretty lightweight and customizable. I still need to check whether it works fine inside UpdatePanel and whether it can be used with RequiredFieldValidator or so.

Color Picker

The ColorPicjker is just an extender to TextBox control. This means a lot of opportunities and promises less problems with validators, etc… It’s a very nice one too.

Combo Box

The ComboBox is a control that is like a DropDownList with auto complete except that the user can enter a new text that is NOT in the existing items. This is good or bad based on your sole use.

I did not like how it’s not well styled in the example page. This means it’s going to be headache to style in my sites as well, which is one of the biggest problems with AJAXToolkit in general.

This is problematic with ASP.NET AJAX. The main Script Components are NOT sent to the client when in :Legacy” mode. This is “By design” in ASP.NET AJAX, although it is a clear limitation!!

I’m investigating the problem for other solutions and will be sending an update soon.

Thank you, Iman Halawany, for making me note this. I’ve been working on WCF services and ASP.NET MVC stuff lately than normal webforms, so, didn’t realize this obvious showstopper.

To all my readers, I owe you a BIG apology.

The Problem

ASP.NET validators and ValidationSummary controls are rendered as SPAN tags that are shown and hidden based on validation state. The properties of the validators are written normally via JavaScript calls similar to these:

ASP.NET, ASP.NET 2.0, ASP.NET Controls

If you have ever thought that the famous if(Page_ClientValidate("validationGroup")) {/*JS Code*/}  and myValidator.ValidationGroup = "validationGroup"; are sure not enough client side capabilities in ASP.NET validators, you are right.

The list of client side API for ASP.NET Validators can be found on this MSDN page "ASP.NET Validation in Depth":

http://msdn.microsoft.com/en-us/library/aa479045.aspx#aspplusvalid_properties

Look for subtitle: "Client-Side APIs".

 

Thanks Simone Chiaretta for mentioning the topic, Mohamed Tayseer for sharing the topic on facebook, and Richard Cook for his comment on the post making me search for the complete list.

The Problem

In an N-tier application, you keep your logic in a business logic tier, typically a different VS project that can be used from a website, a windows service, or desktop application, and that should be valid to writ unit tests against on its own.

But how about if your requirements say that you need to to upload some file for the business logic to work? Think of a scanned image (signed contract maybe?) or just a comma separated value file containing some emails.  Typically the business logic tier will be the place to to handle this, but how can you send the uploaded file to it? You can get the file as "HttpPostedFile" from the "Request.Files" collection or the file upload control itself, but, to receive it in the business logic, project, the easiest way is to add reference to "System.Web" dll and accept the type "HttpPostedFile" as method argument or so, and when in need to save the file physically, you call the "SaveAs" method of "HttpPostedFile" … So simple right ?
