New Dialog Widget
The Dialog is completely new for the R3 release and like the Kendo UI Window component, it requests an action from the user via a popup dialog in your web applications. It differs from the Window component in that it has a few additional features like an optional title and a footer containing one or more buttons. The Dialog control's display is consistent with the current theme and supports content localization.
Data Entry Enhancements
The primary focus of the Kendo UI for jQuery R3 release will be data entry enhancements. Improvements have been made in simple widgets like the numeric textbox all the way through to enhancements in our more complex widgets like the Spreadsheet. The R3 Release is full of new and updated features that will make your data entry applications better than ever.
Dropdowns / Numeric Usability Enhancements
There are numerous enhancements to our popular Dropdowns widget group which includes the DropDownList, ComboBox, MultiSelect and Autocomplete widgets. Enhancements include the addition of a footer template permanently displayed at the bottom of the items list, the addition of a No Data template which displays when the filter applied does not match any results, the ability to automatically adjust the width of a DropDownList to the width of the widest member in the list and for the ComboBox the ability to clear the currently selected or entered value and copying the MaxLength attribute to the generated HTML <input> element.
Upload Improvements
Upload API improvements in R3 focus on providing for a more robust developer experience. Enhancements include support for a Drag and Drop custom drop zone, the ability to specify the file types to be uploaded, the ability to remove a single file and the ability to clear the widget bringing it back to its original state.
