还是winfrom存局的问题，用户拖拽datagridview，改变了DG的大小，可是DG的滚动条却没有了？
先说说都设置了什么属性
DG放在一个panel中，
panel设置的属性有
autoscroll=true

DG设置的属性中
dock=fill
其它略...

在我执行了对DG的拖拽之后，DG的滚动条居然没有了，横的竖的都没有了。下面是拖拽时的代码

C# code

        private void dgvCarList_MouseMove(object sender, MouseEventArgs e)        {            if (e.Y > -3 && e.Y < 3)            {                this.dgvCarList.Cursor = this.btnCurSizeNs.Cursor;            }            else            {                if (this.IsdgvMove == true)                {                    this.dgvCarList.Cursor = this.btnCurSizeNs.Cursor;                }                else                {                    this.dgvCarList.Cursor = this.btuCurZhengChang.Cursor;                }            }        }        private void dgvCarList_MouseDown(object sender, MouseEventArgs e)        {            if (e.Y > -3 && e.Y < 3)            {                this.IsdgvMove = true;            }        }        private void dgvCarList_MouseUp(object sender, MouseEventArgs e)        {            if (!this.IsdgvMove)            {                return;            }            this.panControl.Size = new Size(this.panControl.Width, this.panControl.Size.Height + e.Y);            this.panList.Size = new Size(this.Size.Width, this.Size.Height - e.Y);            this.panList.Location = new Point(this.panList.Location.X, this.panList.Location.Y + e.Y);            this.IsdgvMove = false;        }
