Features

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.

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 superior responsiveness.
