Returns

Type Description
BaseHitInfo

A BaseHitInfo class descendant that contains information about the View elements located at the test point.

Remarks

Use the CalcHitInfo method to determine which element is located at a specific point. For instance, this can be used when handling the View's Click event to determine which element was clicked. In such instances, you will pass the current mouse pointer's coordinates as the method's parameter.

When called for card, grid and Banded Grid Views this method returns the CardHitInfo, GridHitInfo and BandedGridHitInfo objects respectively. Refer to these topics for details on what information is provided by the method's return value.

The Hit Information topic provides general information on obtaining and using hit information.

NOTE

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CalcHitInfo member must not be invoked for these Views. The CalcHitInfo member can only be used with real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
