Return m_binddataview; ???????} ??????? {? ?????????? m_binddataview = value; ????} ??} ?? protected override void paint (system.drawing.graphchics g, ??? system.drawing.Rectangle Bounds, System.Windows. Forms.CurrencyManager ??? source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush ??? foreBrush, bool alignToRight) ?? {????? // the idea is to conditionally set the foreBrush and / or backbrush ????? // depending Upon Some CriRia on the Cell V Alue ????? // Here, We Color Anything That Begins with a letter higher Than 'f' ????? try ????? {??????????? // from DataView Take the value, "itemtype" is the name of the line ????????????
