This demo showcases the two different rendering modes of Telerik ASP.NET Grid control: Classic and Lightweight.

  • Classic rendering is the long-standing rendering mode of the control, with extensive use of table elements for the layout and images for backgrounds, icons, etc.
  • Lightweight rendering leverages HTM5 and CSS3, but the control may lose its rounded corners, gradients and shadows in non-modern browsers.

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 RadGrid 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 for the currently selected RenderMode, so if you want to compare the markup size of both modes, you could change the selection in RenderMode radio button placed in the demo configurator.

* Lightweight rendering uses shared font icons across all controls (TelerikWebUI).
