TDrawGrid.OnSetCheckboxState property

Declaration

property OnSetCheckboxState:;

Description

OnSetCheckboxState is a TSetCheckboxStateEvent property with the event handler signalled to set the state for a check box cell. The ACol and ARow parameters contain the position for the cell. Value contains the TCheckBoxState value stored in the cell.

OnSetCheckboxState provides the only mechanism to set the state value for a check box cell in TCustomDrawGrid / TDrawGrid. This differs from TCustomStringGrid / TStringGrid, where the TGridColumn instance in Columns can is used (when enabled) to get the checked or unchecked value and determine the state value stored in the cell. This approach can be implemented in the event handler; it is not provided by default.

OnSetCheckboxState is signalled (when assigned) from the SetCheckBoxState method.

Use OnGetCheckboxState to get the state for the check box cell.
