努力+方法=成功

Answer 2

我的拖动到第一列的滚动条向左移动的代码
                            //当拖动到第一列时,滚动条向左移动
                            if (e.ColumnIndex == this.FirstDisplayedScrollingColumnIndex)
                            {
                                if (this.HorizontalScrollingOffset > 0)
                                {
                                    if (this.FirstDisplayedScrollingColumnHiddenWidth != 0)
                                    {
                                        this.HorizontalScrollingOffset -= this.FirstDisplayedScrollingColumnHiddenWidth;
                                    }
                                    else
                                    {
                                        this.HorizontalScrollingOffset -= 2;
                                        this.HorizontalScrollingOffset -= this.FirstDisplayedScrollingColumnHiddenWidth;
                                    }
                                }
                            }
这几句代码倒是很好，拖动到最后一列时，滚动条向右移动的代码
                            if (this.HorizontalScrollingOffset < this.HorizontalScrollBar.Maximum)
                            {
                                this.HorizontalScrollingOffset += 3;// this.Columns[this.FirstDisplayedScrollingColumnIndex].Width - this.FirstDisplayedScrollingColumnHiddenWidth;
                            }
                         有些不是很流畅，而且向右拖动时，我的拖动的一条标志线弯曲了，向左拖动时没有问题，向右拖动有没有什么更好的代码，谢谢开心、周雪峰等版主

所谓的标志线是我为了在拖动列时为了方便看到加了一条线，拖动到最后一列时，滚动条向右移动的更好的代码
