Even in relatively small projects, in fact, it can lead straight to a proliferation of controls.For example, you can end up with a regular text box, plus a numeric text box, a filtered text box, a text box that changes its style when focused, a text box that displays a prompt when left empty, and so on.The online documentation provides some good tutorials on how to build extenders. A fair number of sample extenders and additional rich client controls are provided through a separate download-the AJAX Control Toolkit (ACT). In addition, plenty of custom controls are available for developers from third-party vendors, from community projects, and even from contributions by volunteers.In this chapter, I’ll first review the syntax and semantics of control extenders and then take you on a tour of the major components in the ACT. If you need a text box with a set of features that the ASP.NET developers or, at least, Web developers with strong server-side skills.Unfortunately, for the time being, there’s no way to add rich capabilities and functionalities to the Web client other than by crafting good and tricky Java Script code. NET AJAX takes up the challenge and provides two ways for developers to build rich Web applications using a server-centric development approach.
For example, if I have the values set on min = 0 and max = 100, the Y-axis ...
Visual Studio Express provides a free development tool that makes ASP.
Chrome recently updated to version 32.0.1700.72 which has caused issues with drag-and-drop from a Rad Grid once the page has been scrolled. product=grid, scrolling down slightly then attempting to drag an item from the radgrid to the scheduler.
Virtually all behaviors require the injection of some script code in the client page. As a result, the original control looks and behaves in a slightly different manner while its programming interface remains intact.
For this reason, extenders are naturally associated with ASP. From a technology stand-point, on the other hand, ASP. To some extent, the concept of a “behavior” is similar to a theme.
