-SPECIFIC CONTROLS
-
-Some Prado controls were based on specific extensions of the prototype+scriptaculous javascript framework, and they have been deprecated now that jQuery has become the primary js framework in prado.
-While we provide the jQuery-based counterpart for these controls and encourage everyone to port their code, the old controls are still supposed to work with some minor annoyance:
- * prototype and scriptaculous will be loaded along jQuery;
- * jQuery will be put in "no conflict" mode, so the $() helper won't call anymore jQuery but prototype.
-
-Following is the list of deprecated controls.
----
-TAutoCompleter is deprecated, use TJuiAutoComplete instead.
-In the case you want to update your code:
- * No more Frequency property.
- * minChars property is now minLength
- * only the ItemTemplate is supported for the Suggestions repeater (no HeaderTemplate, FooterTemplate, ...);
- * in the ItemTemplate you don't need to render the <li/> anymore, but only the content itself
- * No Multiple selection support (by now, can be added in the future)
----
-TDraggable is deprecated, use TJuiDraggable instead.
-In the case you want to update your code:
- * Check jQuery-ui's Draggable options.
----
-TDropContainer is deprecated, use TJuiDroppable instead.
-In the case you want to update your code:
- * Check jQuery-ui's Droppable options.
- * The event parameter format has changed a bit.
