Methods

Name	Description
AfterExport	Called by the grid after export is complete; restores any state changed by BeforeExport. (inherited from TTMSFNCDataGridCell)
BeforeExport	Called by the grid before export begins; prepares the cell for export rendering. (inherited from TTMSFNCDataGridCell)
ClearControlCache	Invalidates and releases the cached control bitmap so the control is re-rendered on the next draw. (inherited from TTMSFNCDataGridCell)
Draw	Performs a full repaint of the cell using AGraphics; calls DrawBackground, DrawContent, and all other draw sub-steps. (inherited from TTMSFNCDataGridCell)
DrawBackground	Draws the cell background fill and border stroke according to the current Layout. (inherited from TTMSFNCDataGridCell)
DrawCommentIndicator	Draws the comment indicator triangle in the cell corner when CommentIndicator is True. (inherited from TTMSFNCDataGridCell)
DrawContent	Draws all cell content (text, control, sort indicator, filter button, comment indicator). (inherited from TTMSFNCDataGridCell)
DrawControl	Draws the embedded control bitmap or live control within the cell's control rectangle. (inherited from TTMSFNCDataGridCell)
DrawFilterButton	Draws the inline filter button glyph when FilterButton is True. (inherited from TTMSFNCDataGridCell)
DrawSortIndicator	Draws the sort-direction indicator glyph according to SortIndicator. (inherited from TTMSFNCDataGridCell)
DrawText	Draws the cell text string inside the TextRect according to the current Layout alignment and trimming settings. (inherited from TTMSFNCDataGridCell)
HandleKey	Delivers a keyboard event to the cell; subclasses override to handle key interactions. (inherited from TTMSFNCDataGridCell)
HandleMouse	Delivers a mouse event to the cell; subclasses override to handle mouse interactions. (inherited from TTMSFNCDataGridCell)
IsHTML	Returns True when the cell's text contains HTML markup that the renderer should parse. (inherited from TTMSFNCDataGridCell)
ReInitialize	Re-initialises a pooled cell instance with new coordinates and data without allocating a new object. (inherited from TTMSFNCDataGridCell)
XYToAnchor	Returns the anchor URL at canvas position (X, Y) within the cell, or an empty string when no anchor is hit. (inherited from TTMSFNCDataGridCell)

Events

Name	Description
OnChange	Event fired when the user changes the checked state of the control. (inherited from TTMSFNCDataGridCheckedCell)
