wwDBGrid.Canvas.Brush.Color:=clRed;
wwDBGrid.Canvas.FillRect(Rect);
wwDBGrid.Canvas.Font.Color:=clYellow;
wwDBGrid.Canvas.TextOut(Rect.Left,Rect.Top,Field.DisplayText);

使用了以上方法後...原來數值欄位在DBGRID裡會靠右對齊的..後來就變靠左了??

請問,這該怎麼解決呢?

您好,試試這樣

if Column.DefaultAlignment=taRightJustify then
DBGrid1.Canvas.TextOut(Rect.Right-Length(Column.field.displayText)*8,Rect.Top,Column.Field.DisplayText)
else
DBGrid1.Canvas.TextOut(Rect.Left,Rect.Top,Column.Field.DisplayText)
