This was because the j Query validate implementation for a select uses .val() on the element.
In the case of the ej Drop Down List, this returned the first value from the list, though the get Selected Value method of the instance showed that there was no selection (as did the hidden input element for the column/cell.
Using a library to do form validation can save lots of your development time. j Query Form validation library is the most popular validation library.
This post collects all my notes and references on j Query Form validation library.
This document was originally published on February 29, 2012. This method provided streaming access to the request entity. NET 4.5 from methods let you asynchronously read the request entity in chunks, while ASP.The XHTML 1.1 specification is the strictest of these levels.The XHTML 1.0 Frameset and Transitional specifications define XML-based HTML markup, but allow certain widely used constructs.For example, if some upstream code in the pipeline has already read the request entity using .This lets you perform asynchronous processing on a request (for example, streaming a large file upload to a database), but still run pages and MVC ASP. Sending responses to an HTTP client can take considerable time when the client is far away or has a low-bandwidth connection. NET buffers the response bytes as they are created by an application. NET then performs a single send operation of the accrued buffers at the very end of request processing. NET 4.5 supports these simplifications with new APIs that let you write asynchronous HTTP modules and asynchronous HTTP handlers using the new compiler enhancements.Now suppose that you want to use this asynchronous method in an asynchronous ASP. NET performs request validation — it examines requests to look for markup or script in fields, headers, cookies, and so on. Developers have frequently asked for the ability to selectively turn off request validation for their applications.
