The example implements a custom FilterCell Template in order to prevent filtering until the user presses the “Apply" button. It overrides the Autofilter's default behavior (applying the filter after each input control loses focus).
Update:
Starting with version v2013 vol 2.5, we have implemented the new 'on click' filter mode. In this mode, a filter is applied to the grid by clicking the Apply button, which is displayed in a command column.
To provide your application with this functionality, display the filter row in the grid by setting the ShowFilterRow property to true and set the FilterRowMode property to OnClick.
