添加具有Vista樣式的拖放行為到您的web應(yīng)用程序
WebDragDropExtender的多功能的拖放技術(shù)是您能夠創(chuàng)建具有復(fù)雜的Vista工具提示行為和樣式的更強(qiáng)大的web應(yīng)用程序。光標(biāo)效果提供了一個(gè)行為的指示器——例如,當(dāng)顯示為“X”時(shí),表示是一個(gè)無效的拖放目標(biāo)。透明陰影創(chuàng)建一個(gè)拖動(dòng)對(duì)象的持久的視圖。鍵盤狀態(tài)提供各種不同的放置行為——例如,按CTRL鍵復(fù)制放置的對(duì)象或按SHIFT鍵將其移動(dòng)。
與其他Intersoft組件的整合
高度集成的能力和可擴(kuò)展的WebDragDropExtender與其他的Intersoft控件集成。作為一個(gè)預(yù)定義的接口和基類實(shí)現(xiàn),WebDragDropExtender的開放式體系結(jié)構(gòu)API使得實(shí)現(xiàn)一個(gè)自定義的具有一致性和可靠性行為的拖放。在版本中專門設(shè)計(jì)的功能提供了一個(gè)增強(qiáng)的集中Intersoft組件的支持水平,這些組件有WebGrid, WebDesktopManager,和WebNavPane。

輕松添加拖放的數(shù)據(jù)驗(yàn)證
當(dāng)您的應(yīng)用程序需要更復(fù)雜的放置的對(duì)象的post-drop驗(yàn)證。WebDragDropExtender通過在一個(gè)客戶端事件處理器中使用自定義對(duì)象實(shí)現(xiàn)這種驗(yàn)證。測(cè)試對(duì)象使用GetDataPresent方法并很容易地確定被放置對(duì)象的類型。
自動(dòng)回發(fā)模式
WebDragDropExtender無論在客戶端或服務(wù)器支持拖放事件處理。處理時(shí)間客戶端執(zhí)行大多數(shù)任務(wù),例如動(dòng)態(tài)添加或修改一個(gè)HTML元素。調(diào)用服務(wù)器端的處理任務(wù),如保存更改偶的數(shù)據(jù)到數(shù)據(jù)庫(kù)匯中,您甚至能夠使用Intersoft的OnTheFlyPostBack機(jī)制來提供的響應(yīng)速度和驚人的用戶體驗(yàn)。
Add Vista-style drag-and-drop behavior to your web applications.
WebDragDropExtender’s versatile drag-drop technology enables you to create more powerful web applications with sophisticated Vista tooltip behaviors and styles. Cursor effects provide an action indicator – for example, displaying as an “X” to indicate an invalid drop target. Transparent shadows create a persistent view of the dragged object. Keyboard states provide varied drop behavior – for example, hit CTRL to copy the dropped object or press the SHIFT key to move it.
Integrate smoothly with other Intersoft components
The highly capable and extensible WebDragDropExtender integrates smoothly with other Intersoft controls. Implemented as a set of predefined interfaces and base classes, WebDragDropExtender‘s open-architecture API enables a custom drag-and-drop implementation with consistent and reliable behaviors. Special design features in the newest release provide an enhanced level of support for several Intersoft components, such as WebGrid, WebDesktopManager, and WebNavPane. 
Easily add drag-and-drop data validation
When your application requires a more sophisticated post-drop validation of the dropped object, WebDragDropExtender achieves this through the use of custom objects in a client-side event handler. Test objects using the GetDataPresent method and easily determine the type of the dropped object.
Automatic postback mode
WebDragDropExtender supports drag-and-drop event handling at either client or server. Handle events client-side to perform most tasks, such as adding or changing an HTML element dynamically. Invoke server-side handling for tasks such as saving modified data to a database. You can even use Intersoft’s OnTheFlyPostBack technology for unsurpassed responsiveness and amazing experience.
