Question

我有一个以mdi parent加载的子表单。这个子表单在加载时有滑动效果，从屏幕左侧开始，将设置在屏幕中心（我用简单的计时器完成）。

问题在于，如果我没有将表单的dockstyle设置为fill，则滚动条不起作用，如果我将dockstyle设置为fill，则滑动效果不会工作和形成负载简单！

这是form1中的按钮：

    Timer timerPrevMonth = new Timer();
    //reserve_vaght_azar is the form that will be load in sliding effect
    reserve_vaght_azar reservevaghtazar = null;
    private void btn_prev_dey_Click(object sender,EventArgs e)
    {

        reservevaghtazar = new reserve_vaght_azar();
        reservevaghtazar.StartPosition = FormStartPosition.Manual;
        reservevaghtazar.Location = new Point( this.Location.X-Width,Location.Y );
        reservevaghtazar.MdiParent = MdiParent;
        this.TopMost = true;
       //here is dockstyle
       // reservevaghtazar.Dock=DockStyle.Fill;
        reservevaghtazar.Show();
        timerPrevMonth.Start();
    }

这是计时器功能：

    void timerPrevMonth_Tick(object sender,EventArgs e)
    {
        timerPrevMonth.Stop();
        reservevaghtazar.Location = new Point( reservevaghtazar.Location.X +15,this.Location.Y );

        if (this.Location.X-reservevaghtazar.Location.X <5)
        {
            reservevaghtazar.Location = new Point( this.Location.X,this.Location.Y );
            this.TopMost = false;
            reservevaghtazar.BringToFront();
            reservevaghtazar.Focus();

        }
        else
            timerPrevMonth.Start();
    }

当在form1中按下按钮时，表单reserve_vaght_azar将加载滑动效果

我解决了！

我只是在reservevaghtazar.Dock=DockStyle.Fill;

之后添加了reservevaghtazar.Focus();

问题是我在幻灯片表单完全加载到屏幕之前对接表单。我改变了对接线的位置并解决了。

但是如果表单没有填写Mdi父级，那么滚动条无法正常运行。

滚动条在Mdi子幻灯片表单中不起作用
