This demo showcases the two different rendering modes of Telerik's ASP.NET OrgChart control: Classic and Lightweight.
There is also a Native render mode option inherited directly from RenderMode. As OrgChart does not have a specific HTML element, the Native render mode will have the same effect as the Classic one.
The default render mode of the control is Classic and you have the option to either explicitly set it to Lightweight or leverage the Auto mode to have the control choose the best rendering based on the user's browser.
Note: In order to provide optimal experience for your end users, we recommend that you use only one type of render mode for a control on a given page. For example, if you have two instances of RadFormDecorator on the page, it will be best if both of them use the same render mode.
Note: The Material skin is available only for the modern Lightweight render mode. Change the skin or the mode to properly visualize the demonstrated control.
Notes on the statistics: *The markup size is calculated automatically in the code-behind by rendering a simple OrgChart instance on a blank page. **The image sprite that causes the increase in size is a common one, used by various Telerik controls on the page, so with more controls the benefits will be more apparent.
