    • Select Elements To Edit

    Apart from defining appearance to the diagram’s elements from the corresponding server-side properties, the rich client-side API of the underlying Kendo UI HTML5 Diagram widget offers the ability to dynamically modify these configurations.

    This demo demonstates how to use the client-side API of the diagram control and more precisely the redraw(options) method of Diagram items, where options defines the changes that you want to apply to the specified shape or connection.
