Version Q1 2012 released 04/11/2012

Input / First Look

Example Configuration
select

  • Since Q3 2011 RadInput has a new rendering mode. This mode is controlled through the EnableSingleInputRendering property. Since Q1 2012 it is set to true by default and the RadInput controls use a single input of type text to keep the entered values. Whereas with the non-single input rendering mode, two or three inputs of type text are rendered.

    Enabling the single input rendering mode improves the page performance and allows for easier customizations.

    This demo illustrates what would be the rendered html for the different RadInput controls, namely RadTextBox, RadnumericTextBox, and RadDateInput. Using the configurator above, you can enable/disable particular features and see how the rendering is changed and compare it with this of the non-single input rendering mode.
