Class ModalDialog - West Wind Toolkit for .NET

Class ModalDialog

This control allows creating client side pop up window that blocks out the background and brings a dialog to the foreground. This control can be used to replace ugly alert or prompt boxes to pop up rich dialogs that must be edited modally. Any dialog can be popped up like

The background can be just an opaque color with a transparency value - the default is black at 70% for example which gives a grey looking overlay - or can be a custom Html element that is expanded and then made transparent as in the following figure.

The control is based on DragPanel so the dialogs can be draggable and closable. Events are available to fire when a button or the close button is clicked with event firing either on the client or server.

The client side counter part class can be used without this server side control and allows a few extra features, such as a mechanism to display a dialog without controls on the page to map to.
