TcxGridChartSeries.OnCustomDrawValue Event

Occurs when a data marker in the series needs to be painted.

Declaration

property OnCustomDrawValue: TcxGridChartSeriesValueCustomDrawEvent read; write;

Remarks

The OnCustomDrawValue event occurs every time a data marker needs to be painted. As with other custom draw events it provides a canvas for the grid control (the ACanvas parameter), ViewInfo (the AViewInfo parameter and its Bounds property) to get the bounding rectangle of the painted element (in this case the data marker). Sender is usually the element that caused the repaint. The ADone parameter’s value is initially set to False. Set it to True to tell the grid that you have finished drawing the data marker of the series. In this case the diagram’s OnCustomDrawValue event for the series won’t be fired.
