ASP .NET AJAX Control Toolkit

*Accordion : that allows you to provide multiple panes and display them one at a time.

AlwaysVisibleControl : allowing you to pin controls to the page so that they appear to float over the background body content when it is scrolled or resized.

*Animation : It's a pluggable, extensible framework for easily adding animation effects to your web pages.

The sample below demonstrates a composite animation consisting of four primary animation actions, done in parallel:

    * Move (to move the panel to its final location)
    * Resize (to change the size of the panel)
    * Fade (to fade the text in/out)
    * Color (the flyout changes from gray to white and the text pulses red)

*AutoComplete (New!) : that can be attached to any TextBox control, and will associate that control with a popup panel to display words that begin with the prefix typed into the textbox.

*Calendar (New!) : that can be attached to any ASP.NET TextBox control. It provides client-side date-picking functionality with customizable date format and UI in a popup control. You can interact with the calendar by clicking on a day to set the date, or the "Today" link to set the current date.

*CascadingDropDown : that can be attached to an ASP.NET DropDownList control to get automatic population of a set of DropDownList controls. Each time the selection of one the DropDownList controls changes, the CascadingDropDown makes a call to a specified web service to retrieve the list of values for the next DropDownList in the set.

*CollapsiblePanel : that allows you to easily add collapsible sections to your web page. This extender targets any ASP.NET Panel control. The page developer specifies which control(s) on the page should be the open/close controller for the panel, or the panel can be set to automatically expand and/or collapse when the mouse cursor moves in or out of it, respectively.

*ConfirmButton : that catches clicks on a button (or any instance of a type derived from Button) and displays a message to the user. If the "OK" button is clicked, the button or link functions normally. If not, the click is trapped and the button will not perform its default submit behavior. This is useful for delete links or anything else that requires confirmation from the user.

DragPanel : allows users to easily add "draggability" to their controls. The DragPanel targets any ASP.NET Panel and takes an additional parameter that signifies the control to use as the "drag handle". Once initialized, the user can freely drag the panel around the web page using the drag handle.

*DropDown : that can be attached to almost any ASP.NET control to provide a SharePoint-style drop-down menu.

*DropShadow : which applies a "Drop Shadow" to a Panel.

*DynamicPopulate : that replaces the contents of a control with the result of a web service or page method call. The method call returns a string of HTML that is inserted as the children of the target element.

*FilteredTextBox : which prevents a user from entering invalid characters into a text box. Note that since this effect can be avoided by deactivating JavaScript, you should use this extender as a convenience for your users, but you must never expect that the data being sent to the server consists of "valid" chars only.

*HoverMenu : that can be attached to any ASP.NET WebControl, and will associate that control with a popup panel do display additional content.

*MaskedEdit (New!) : that can be attached to a TextBox control. When using MaskedEdit the input is masked and the value is validated on the client according to the data type chosen. To achieve the validation, the extender is hooked up to a MaskedEditValidator that verifies the input and feeds it to a set of ASP.NET validators.

ModalPopup : allows a page to display content to the user in a "modal" manner which prevents the user from interacting with the rest of the page.

*MutuallyExclusiveCheckBox : that can be attached to any ASP.NET CheckBox control. By adding a number of checkboxes to the same "Key", only one checkbox with the specified key can be checked at a time.

NoBot : NoBot is a control that attempts to provide CAPTCHA-like bot/spam prevention without requiring any user interaction. This approach is easier to bypass than an implementation that requires actual human intervention, but NoBot has the benefit of being completely invisible. NoBot is probably most relevant for low-traffic sites where blog/comment spam is a problem and 100% effectiveness is not required.

NumericUpDown : NumericUpDown is an ASP.NET AJAX extender that can be attached to an ASP.NET TextBox control to add "up" and "down" buttons that increment and decrement the value in the TextBox. The increment and decrement can be simple +1/-1 arithmetic, they can cycle through a provided list of values (like the months of the year), or they can call a Web Service to determine the next value. Page authors can also provide custom images to be used instead of the default up/down button graphics.

PagingBulletedList : PagingBulletedList is an ASP.NET AJAX extender that can be attached to an ASP.NET BulletedList control and provide client-side sorted paging. It is very flexible and lets you specify either the number of characters used in the heading indices or the maximum number of items to display per index. If the input is not sorted (either on the server or client), it will generated more header indices but still function appropriately.

PasswordStrength : PasswordStrength is an ASP.NET AJAX extender that can be attached to an ASP.NET TextBox control used for the entry of passwords. The PasswordStrength extender shows the strength of the password in the TextBox and updates itself as the user types the password. The indicator can display the strength of the password as a text message or with a progress bar indicator. The styling and position of both types of indicators is configurable. The required strength of the password is also configurable, allowing the page author to tailor the password strength requirements to their needs. The text messages that describe the current strength of the password can also be configured. Additionally, a help indicator can be used to provide explicit instructions about what changes are required to achieve a strong password. The indicator is displayed when the user begins typing into the TextBox and is hidden from view once the TextBox loses focus.

PopupControl : PopupControl is an ASP.NET AJAX extender that can be attached to any control in order to open a popup window that displays additional content. This popup window will probably be interactive and will probably be within an ASP.NET AJAX UpdatePanel, so it will be able to perform complex server-based processing (including postbacks) without affecting the rest of the page. The popup window can contain any content, including ASP.NET server controls, HTML elements, etc. Once the work of the popup window is done, a simple server-side call dismisses it and triggers any relevant script on the client to run and update the page dynamically.

*Rating : The Rating control provides an intuitive rating experience that allows users to select the number of stars that represents their rating. The page designer can specify the initial rating, the maximum rating to allow, the alignment and direction of the stars, and custom styles for the different states a star can have. Rating also supports a ClientCallBack event that allows custom code to run after the user has rated something.

ReorderList : ReorderList is an ASP.NET AJAX control that implements a bulleted, data-bound list with items that can be reordered interactively. To reorder the items in the list, the user simply drags the item's control bar to its new location. Graphical feedback is shown where the item will be placed as it is dragged by the user. The data source is updated after the item is dropped in its new location.

ResizableControl : ResizableControl is an extender that attaches to any element on a web page and allows the user to resize that control with a handle that attaches to lower-right corner of the control. The resize handle lets the user resize the element as if it were a window. The appearance of the resize handle can be specified by the page designer with a CSS style. The content within the element can use CSS styles to automatically resize to fit the new dimensions. Alternatively, ResizableControl exposes two events (onresizing and onresize) that the page designer can attach custom script to in order to enable more complex layout logic. Element dimensions are preserved across postbacks to the server and "size" properties accessible on both the client and server can be used to enable custom resize behaviors. ResizableControl can optionally limit the maximum and minimum width and height of the target control so that resizing can be constrained by the page author (for example, to limit scrolling to only the horizontal dimension).

RoundedCorners : The RoundedCorners extender applies rounded corners to existing elements. To accomplish this it inserts elements before and after the element that is selected, so the overall height of the element will change slightly. You can choose the corners of the target panel that should be rounded by setting the Corners property on the extender to None, TopLeft, TopRight, BottomRight, BottomLeft, Top, Right, Bottom, Left, or All.

Slider : The Slider extender allows to upgrade an asp:TextBox to a graphical slider that allows the user to choose a numeric value from a finite range. The Slider's orientation can be horizontal or vertical and it can also act as a "discrete" slider, allowing only a specified number of values within its range.

*Tabs (New!) : TabContainer is an ASP.NET AJAX Control which creates a set of Tabs that can be used to organize page content. A TabContainer is a host for a number of TabPanel controls.
Each TabPanel defines its HeaderText or HeaderTemplate as well as a ContentTemplate that defines its content. The most recent tab should remain selected after a postback, and the Enabled state of tabs should remain after a postback as well.

*TextBoxWatermark : TextBoxWatermark is an ASP.NET AJAX extender that can be attached to an ASP.NET TextBox control to get "watermark" behavior. When a watermarked TextBox is empty, it displays a message to the user with a custom CSS style. Once the user has typed some text into the TextBox, the watermarked appearance goes away. The typical purpose of a watermark is to provide more information to the user about the TextBox itself without cluttering up the rest of the page.

ToggleButton : ToggleButton is an ASP.NET AJAX extender that can be attached to an ASP.NET CheckBox control. ToggleButton enables the use of custom images to show the state of the CheckBox. The behavior of the CheckBox is unaffected.

UpdatePanelAnimation : The UpdatePanelAnimationExtender is a simple extender that allows you to utilize the powerful animation framework with existing pages in an easy, declarative fashion. It is used to play animations both while an UpdatePanel is updating and after it has finished updating.

ValidatorCallout : ValidatorCallout is an ASP.NET AJAX extender that enhances the functionality of existing ASP.NET validators. To use this control, add an input field and a validator control as you normally would. Then add the ValidatorCallout and set its TargetControlID property to reference the validator control.
