void CBCGPGridCtrl::SetShowInPlaceToolTip ( BOOL  bShow = TRUE)

Enables or disables in-place tooltips.

The library implements custom tooltips that can be positioned exactly over grid cells. When a grid item is partially visible, a tooltip pops up. Use this function to enable or disable custom tooltips. If the custom tooltip is disabled, the grid displays the standard tooltip, which is positioned below the cell.

bShowIf TRUE, the custom tooltip will be shown. If FALSE, the standard tooltips will be shown.
