Delphi dbgrideh颜色设置

DBGridEh中分行分列、单元格的颜色设置
（1）分行不同颜色设置；在DBGridEh1DrawColumnCell中写；

     if ADOQuery1.RecNo mod 2=0 then
     begin
         DBGridEh1.Canvas.Font.Color := clRed;
         DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
     end
     else begin
         DBGridEh1.Canvas.Font.Color := clGreen;
         DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
     end;

（2）分行不同背景颜色设置；在DBGridEh1DrawColumnCell中写；

     if ADOQuery1.RecNo mod 2=0 then
     begin
         DBGridEh1.Canvas.Brush.Color := clRed;
         DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
     end
     else begin
         DBGridEh1.Canvas.Brush.Color := clGreen;
         DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
     end;

（3）符合条件的单元格颜色或者背景颜色设置；在DBGridEh1DrawColumnCell中写；

     if Column.FieldName='价格' then
     begin
         if ADOQuery1.FieldByName('价格').AsFloat<0 then
         begin
             DBGridEh1.Canvas.Font.Color := clRed;
             DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
         end;
     end;

（4）交叉设置列颜色
          1、为DBGridEh的每列的Color属性设置值。
          2、将DBGridEh的RowColorFlag设为false;


=================================================================我自己的==============================

procedure TfrmMain.UserShowDbgehDrawColumnCell(Sender: TObject;
  const Rect: TRect; DataCol: Integer; Column: TColumnEh;
  State: TGridDrawState);
begin
  //先判断是否是这列,提升效率,不是这列的就跳过了.
  if Column.FieldName = 'top_user_type' then
  begin
    //然后判断当前值是否符合要求.
    if frmClientDm.UserCds.FieldByName('top_user_type').AsString = '0' then
    begin
      with UserShowDbgeh do
      begin
        //改变颜色
        Canvas.Font.Color := clRed;
        Canvas.Brush.Color := clYellow;
        //重绘单元格
        DefaultDrawColumnCell(Rect, DataCol, Column, GridsEh.TGridDrawState(State));
      end;
    end;
  end;
end;
