WebDragDropExtender

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.

RealTime Operation

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.

RealTime Operation

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.
