event FilterChanging (Group as Group)
Notifies your application that the filter for a group is about to change

TypeDescription
Group as Group A Group object where the filter is about to be change.
The FilterChanging event occurs just before applying the filter. The FilterChange event occurs once the filter is applied, so the list gets filtered. Use the Filter and FilterType properties to retrieve the column's filter string, if case, and the column's filter type. The ApplyFilter and ClearFilter methods fire the FilterChange event. Use the DisplayFilterButton property to add a filter bar button to the column's caption. Use the FilterBarHeight property to specify the height of the control's filter bar. Use the FilterBarFont property to specify the font for the control's filter bar. For instance, you can use the FilterChanging event to start a  timer, and count the time to get the filter applied, when the FilterChange event is fired. 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.
