Syntax
public class GridQueryCoveredRangeEventArgs : GridCellHandledEventArgs
Remarks

GridQueryCoveredRangeEventArgs is a custom event argument class used by the QueryCoveredRange event to query information about covered cells at a specified cell.

This event allows you to specify covered ranges at run-time, e.g when you have a large grid with repeating patterns of covered ranges. If the specified row and column index is part of a covered cell's range, you should assign the coordinates of the covered cell to Range and set Handled to True.

Handled indicates that you supplied data from your event handler and no further querying for data about covered range information for this cell is necessary.

See the VirtualGrid sample for an example of how to use this event.
