AJAX Collapsible Panel Extender Code Behind

Dot Net framework helps to create collapse and broaden functionalities inside easy steps. Ajax device equipment included a management name Ajax Collapsible Panel Extender permits to implement above mentioned process as very easily. The CollapsiblePanel is a really versatile extender that allows you to easily add collapsible sections to your internet page. In above example we looked that how we are able to implement ajax collapsible panel extender throughout the aspx web page. In some situation we have to call this functionality on some javscript events. In these situation, we need to research that how we will name collapse and increase functionalities from javascript. Below is the code for calling ajax collapsible panel extender from javascript. The AccordionExtender management is similar to the CollapsiblePanelExtender control. It lets you group multiple collapsible panels in a single control. At the identical time, it also manages the collapsed and expanded state of each panel; subsequently, expanding one panel at a time. In different words, the AccordionExtender management doesn't help expanding two or more panels simultaneously. Instead, the header templates of all the panels are all the time visible to have the ability to click on any of them to show the hidden contents. By default, the AccordionExtender management opens with one panel as expanded. In Previous submit I explained clearly the way to use Ajax Accordion menu .Now I will explain how to use the Ajax Collapsible panel control in asp.web.

CollapsiblePanelExtender is an asp.web ajax management toolkit's extender management. CollapsiblePanelExtender enable us to create a collapsible part in asp.web web web page. CollapsiblePanelExtender targets any Panel server control. On a shopper postback it may possibly routinely restores its client states. However, it's rare that you have to write a very new management your self. More typically, your management will derive from an current ASP.NET management base class. Blindly utilizing inheritance for constructing specialised variations of controls won't be a wise alternative, although. Even in comparatively small initiatives, in reality, it could lead straight to a proliferation of controls. On the opposite hand, merging all these behaviors right into a single tremendous TextBox management may not be wise either. In this case, the resulting code shall be literally full of branches, logical situations, and properties to verify. For just a easy further feature, you'll load an enormous control. The CollapsiblePanelExtender management is a very versatile extender that allows you to simply add a collapsible part to your webpage.

The collapsiblePanel is used to collapse and increase any internet web page content or controls inside an ASP.Net panel management. A panel management will expand and collapse using a label control or linkbutton management. Event Type Description present.bs.modal This event fires instantly when the present occasion method is known as. If attributable to a click, the clicked factor is on the market as the relatedTarget property of the occasion. Shown.bs.modal This event is fired when the modal has been made visible to the person . Hide.bs.modal This occasion is fired instantly when the hide instance methodology has been known as. Hidden.bs.modal This occasion is fired when the modal has completed being hidden from the user . Loaded.bs.modal This occasion is fired when the modal has loaded content utilizing the distant possibility. The Tick occasion occurs when the time specified within the interval property has elapsed and the page is posted on the server. You can add a quantity of Timer controls on a Web page. Usually the entire web page requires only a single Timer management; nonetheless, you should use a number of Timer controls, if the UpdatePanel controls are being updated at different intervals. The XMLHttpRequest object is utilized by JavaScript to trfer XML and other text information between consumer and server. The XMLHttpRequest object permits a client-side script to carry out an HTTP request. AJAX functions use the XMLHttpRequest object in order that the browser can communicate to the server with out requiring a postback of the complete web page. Thus, we've seen how to construct a simple collapsible panel with div tag and jQuery.

I even have discussed this text with a static content within the panels. We also can load contents only if the consumer expands the content utilizing jquery and json i.e. loading the content from server on demand. Download the source connected with this text and see it in action. In this article we will see how to use a number of loading/waiting pictures within Updatepanel. Sometimes our web site contains a number of controls which performs massive code behind calculations or communication with the database. In some instances these duties take some long time to carry out their actions. At these situations website web page hangs up until the background operation isn't accomplished. This make website customers confused and frustrated as a result of a lot of the customers are not acquainted with the coding. They would possibly assume that web site isn't working they usually constantly hit web site page buttons or refresh their website web page. In the pop-up panel you possibly can optionally determine an OK management and a Cancel management. You set the ID of such controls via the OkControlID and CancelControlID properties. The pop-up conduct is clearly a client-side action, so some JavaScript code could be required in response to the user's clicking the OK or Cancel control. You use the OnOkScript property to specify the JavaScript function to run in case the consumer clicks the OK button; you utilize OnCancelScript otherwise. ASP.NET AJAX is a free framework for constructing a brand new generation of richer, extra interactive, highly customized cross-browser net purposes. This new net development expertise from Microsoft integrates cross-browser client script libraries with the ASP.NET 2.zero server-based improvement framework. In addition, ASP.NET AJAX offers you a similar type of improvement platform for client-based internet pages that ASP.NET offers for server-based pages. And as a result of ASP.NET AJAX is an extension of ASP.NET, it is absolutely integrated with server-based providers.

ASP.NET AJAX makes it possible to simply benefit from AJAX methods on the web and allows you to create ASP.NET pages with a wealthy, responsive UI and server communication. You can benefit from the rich client framework to easily construct client-centric net functions that integrate with any backend knowledge supplier and run on most trendy browsers. This extender controls and provides buttons customers can use to maneuver between images individually and to play the slide show automatically. The CascadingDropDown extender is designed to slot in a relatively common state of affairs during which the contents of one drop-down listing depend upon the number of one other list. For example, suppose you want the user to pick out a country and a city in that nation. To minimize data switch and provide a friendlier person interface, you might wish to keep town list empty until a range is made on the country list. When a rustic is selected, you get back to the server to download the listing of cities out there for that country. The CascadingDropDown extender simplifies this scenario by injecting some glue code into the consumer page and also making some assumptions on the construction of your page code. Imagine you need only the text bins in a given input form to change their type when focused. If you create a new management, say FocusedTextBox, you're fantastic. What if, as a substitute, you need the identical behavior from buttons, examine bins, and drop-down lists? You ought to create a bunch of recent controls-all of which can extend the goal controls with the same logical habits. Extender controls are just a formal way to outline such a conduct. In addition to partial rendering, developers can use control extenders to add a predefined client-side conduct to new and existing ASP.NET controls. A client-side habits is a block of JavaScript code that adds a new capability to the markup generated by a given ASP.NET control.

An extender is mainly a server control that emits proper script code-the client behavior-to improve how a given ASP.NET control behaves on the shopper. An extender isn't merely a customized control derived from an existing management. Rather, it represents a common behavior-such as auto-completion, focus management, generation of popups, and draggability-that can be declaratively applied to numerous goal control sorts. For instance, a special conduct could be utilized to any targeted control-be it a TextBox, Button, or CheckBox management. Here we are going to demonstrate step-by-step process to implement ajax collapsible panel extender in ASP.Net/C#. In order to implement collapsible panel extender we have to embody ajax management toolkit dll as reference to our visible studio. Modern display readers and comparable assistive applied sciences make use of this attribute to offer users with additional shortcuts to navigate on to the collapsible element itself. If no lessons are specified, icons are not be created. A new span is created and appended to the header, the classes for this span are automatically modified whenever the content gets expanded/collapsed. ASP.NET AJAX, largely referred to as AJAX, is a set of extensions of ASP.NET. It is developed by Microsoft to implement AJAX functionalities in Web purposes. ASP.NET AJAX supplies a set of parts that enable the builders to develop purposes that can update only a specified portion of data without refreshing the complete page. The ASP.NET AJAX works with the AJAX Library that uses object-oriented programming to develop wealthy Web functions that communicate with the server using asynchronous postback. Is there any plan to flesh out the shopper side design of the toolkit controls to permit more exercise in Javascript? For example, a quantity of of the controls would possibly profit from exposing client-side Javascript occasions (i.e. Expand/Collapse for the Collapsible Panel control, same factor for the Accordion, etc). Also, many controls have lots of flexibility w/r/t to the other controls/elements they work together with, but many do not. For example, the Password Strength management is very limited.

The text or ugly-looking progress bar MUST be DIRECTLY above, left, under, or proper of the textbox, there isn't a customize-ability for the progress bar layout , and so forth. It could be argued that the same performance may have been utilized to radio buttons as a substitute of verify packing containers. Using check boxes was the choice of builders, and it also supplies a more consistent and expected person interface. However, you probably can re-implement the behavior to use JavaScript to allow the deselection of a radio button item. The ImageControlID signifies the Image control, if any, that if clicked causes the panel to increase or collapse. The ExpandedImage and CollapsedImage properties set the URL of the pictures to use to increase and collapse. Likewise, CollapsedText and ExpandedText set the Tool-Tip text for the picture. Collapsed units the state of the panel, whereas ExpandDirection indicates whether or not the panel expands horizontally or vertically. Figure 5-8 supplies a view of the control in action. A typical extender control is made from a set of properties and a quantity of JavaScript information that, all together, define the anticipated habits of the goal management within the browser. The ASP.NET developer adds extenders declaratively to a server page and configures properties to obtain the specified behavior. ASP.NET AJAX takes up the challenge and supplies two methods for builders to construct rich Web purposes utilizing a server-centric growth strategy. As we mentioned in Chapter four, "Partial Page Rendering," developers can refresh particular areas of the page using partial rendering as an alternative of normal ASP.NET postbacks. To create such regions, you simply use a selected set of server controls-the most important of which is the UpdatePanel management. Collapsed property specify the goal panel should initially be collapsed or expanded. AutoCollapse property allow us to mechanically collapse goal panel when the mouse is moved off.

And AutoExpand property enable us to mechanically expand panel when mouse is moved over. ScrollContents property allow us to add a scrollbar if the content is longer than panel itself. In some scenario we've to create and implement a ajax collapsible panel extender dynamically as per the info from the database in ASP.Net/C#. We can create and implement ajax collapsible panel extender dynamically from code behind in ASP.Net/C# using below talked about code. Recalculates the state of the affix based on the size, place, and scroll position of the related components. The .affix, .affix-top, and .affix-bottom courses are added to or removed from the affixed content material based on the model new state. This technique must be called every time the dimensions of the affixed content or the goal element are modified, to ensure appropriate positioning of the affixed content material. Name sort default description interval number 5000 The period of time to delay between mechanically cycling an item. Pause string | null "hover" If set to "hover", pauses the biking of the carousel on mouseenter and resumes the biking of the carousel on mouseleave. If set to null, hovering over the carousel won't pause it. Wrap boolean true Whether the carousel should cycle constantly or have onerous stops. Keyboard boolean true Whether the carousel ought to react to keyboard events.

Event Type Description show.bs.collapse This occasion fires instantly when the show instance method known as. Shown.bs.collapse This event is fired when a collapse component has been made visible to the consumer . Hide.bs.collapse This event is fired immediately when the disguise method has been known as. Hidden.bs.collapse This event is fired when a collapse component has been hidden from the person . Event Type Description present.bs.popover This event fires instantly when the present occasion methodology is called. Shown.bs.popover This occasion is fired when the popover has been made visible to the consumer . Hide.bs.popover This occasion is fired immediately when the disguise instance method has been called. Hidden.bs.popover This occasion is fired when the popover has finished being hidden from the person . Inserted.bs.popover This occasion is fired after the show.bs.popover event when the popover template has been added to the DOM. Event Type Description present.bs.tooltip This event fires immediately when the show occasion methodology known as.

Shown.bs.tooltip This event is fired when the tooltip has been made seen to the consumer . Hide.bs.tooltip This event is fired instantly when the hide instance method has been known as. Hidden.bs.tooltip This event is fired when the tooltip has finished being hidden from the user . Inserted.bs.tooltip This occasion is fired after the show.bs.tooltip occasion when the tooltip template has been added to the DOM. Name sort default description backdrop boolean or the string 'static' true Includes a modal-backdrop component. Alternatively, specify static for a backdrop which does not shut the modal on click on. Keyboard boolean true Closes the modal when escape secret is pressed show boolean true Shows the modal when initialized. Remote path false This possibility is deprecated since v3.3.zero and has been eliminated in v4. We suggest instead using client-side templating or a data binding framework, or calling jQuery.load yourself. In this text we will see how to create dynamic Jquery repeater utilizing database in Asp .net. Jquery accordion could be very useful if you need to show info in collapsible content panels.
