method Tree.ApplyFilter ()
Applies the filter. /*not supported in the lite version*/


The ApplyFilter method updates the control's content once that user sets the filter using the Filter and FilterType properties. Use the ClearFilter method to clear the control's filter. Use the DisplayFilterButton property to show the filter drop down button in the column's caption. Use the FilterInclude property to specify whether the child items should be included to the list when the user applies the filter. Use the ShowFilter method to show programmatically the column's drop down filter window. The VisibleItemCount property retrieves the number of visible items in the list. The control fires the FilterChanging event just before applying the filter, and  FilterChange once the list gets filtered. The FilterBarPromptVisible property specifies whether the filter prompt is visible or hidden. The filter prompt feature allows you to filter the items as you type while the filter bar is visible on the bottom part of the list area. The Filter prompt feature allows at runtime filtering data on hidden columns too.
