The ! indicates cells that are header cells. In order for a table to be sortable, the first row(s) of a table need to be entirely made up out of these header cells. You can learn more about the basic table syntax by taking the Introduction to tables for source editing.
This is the "raw code" directory. The ASP.NET server automatically compiles files (and subdirectories) in this folder into an assembly accessible in the code of every page of the site. App_Code is typically used for data access abstraction code, model code and business code. Also any site-specific http handlers and modules and Web service ...
Certain jQuery object methods retrieve specific values (instead of modifying a state). An example of this is the val() method, which returns the current value of a text input element. In these cases, a statement such as $('#user-email').val() cannot be used for chaining as the return value does not reference a jQuery object.
With Ajax, web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behaviour of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows web pages and, by extension, web applications, to change content dynamically without ...

The direction data binding happens is configurable - it can be defined to go UI-to-source (eg. text entered into a textbox being propagated to a bound string property in code), or source-to-UI (eg. a visual clock being updated to display the current time stored in code), or bi-directional. [14] Data binding doesn't have any restrictions on ...
Netscape's project to improve HTML layout in Navigator 4 has been cited as an example of a failed rewrite. The new layout engine had developed independently from Navigator and did not integrate readily with Navigator's code; hence Navigator itself was rewritten around the new engine, breaking many existing features and delaying release by several months.
First, the async keyword indicates to C# that the method is asynchronous, meaning that it may use an arbitrary number of await expressions and will bind the result to a promise. [1]: 165–168 The return type, Task<T>, is C#'s analogue to the concept of a promise, and here is indicated to have a result value of type int.
