C#实现运行期控件设计

 

 

  
  
  
  1、实现了控件自由拖动
  
  2、实现了控件的拖动创建,右键删除等类似IDE的控件创建,当然更多功能靠大家自己完善

  3、实现属性框与控件的绑定,可以在运行期修改控件的Text...

 

  以下是部分代码

 

 

 

private void button2_Click(object sender, EventArgs e)
{
    //控件框的显示与隐藏
    if (panel1.Visible == true)
    {
        button2.Text = "+  控件框";
        panel1.Visible = false;
    }
    else
    {
        button2.Text = "-  控件框";
        panel1.Visible = true;
    }
}

private void button2_Click(object sender, EventArgs e) { //控件框的显示与隐藏 if (panel1.Visible == true) { button2.Text = "+ 控件框"; panel1.Visible = false; } else { button2.Text = "- 控件框"; panel1.Visible = true; } }

 

 

 

private void button3_MouseDown(object sender, MouseEventArgs e)
{
    //判断鼠标左键按下
    if (e.Button == MouseButtons.Left)
    {
        Button btn = (Button)(sender);
        //初始化拖放操作。
        btn.DoDragDrop(btn, DragDropEffects.Copy);
    }
}

private void panel4_DragDrop(object sender, DragEventArgs e)
{
    //开始拖动
    Button btn = (Button)(e.Data.GetData("System.Windows.Forms.Button"));
    Button btn_new = new Button();
    btn_new.ContextMenuStrip = contextMenuStrip1;
    btn_new.Name = btn_new.Text = btn.Text + "--" + name;
    btn_new.Left = PointToClient(MousePosition).X-panel4.Left;
    btn_new.Top = PointToClient(MousePosition).Y - panel4.Top;
    //加载事件
    btn_new.Click += new System.EventHandler(this.button1_Click);
    btn_new.MouseLeave += new System.EventHandler(this.button1_MouseLeave);
    btn_new.MouseDown += new System.Windows.Forms.MouseEventHandler(this.button1_MouseDown);
    btn_new.MouseMove += new System.Windows.Forms.MouseEventHandler(this.button1_MouseMove);
    btn_new.Parent = panel4;
    name++;
}

private void button3_MouseDown(object sender, MouseEventArgs e) { //判断鼠标左键按下 if (e.Button == MouseButtons.Left) { Button btn = (Button)(sender); //初始化拖放操作。 btn.DoDragDrop(btn, DragDropEffects.Copy); } } private void panel4_DragDrop(object sender, DragEventArgs e) { //开始拖动 Button btn = (Button)(e.Data.GetData("System.Windows.Forms.Button")); Button btn_new = new Button(); btn_new.ContextMenuStrip = contextMenuStrip1; btn_new.Name = btn_new.Text = btn.Text + "--" + name; btn_new.Left = PointToClient(MousePosition).X-panel4.Left; btn_new.Top = PointToClient(MousePosition).Y - panel4.Top; //加载事件 btn_new.Click += new System.EventHandler(this.button1_Click); btn_new.MouseLeave += new System.EventHandler(this.button1_MouseLeave); btn_new.MouseDown += new System.Windows.Forms.MouseEventHandler(this.button1_MouseDown); btn_new.MouseMove += new System.Windows.Forms.MouseEventHandler(this.button1_MouseMove); btn_new.Parent = panel4; name++; }
