Question

我正在尝试将groupBox2容器中的pictureBox2移动到另一个groupBox1。问题是在那个容器中，还有另一个pictureBox1，当我将pictureBox2移到pictureBox1上时，pictureBox2会在它周围找到一个白框。

总而言之，我想将pictureBox2混合到pictureBox1。

这是我的代码，它包含鼠标移动，上下功能：

    private void pictureBox2_MouseDown(object sender, MouseEventArgs e)
    {
        downPoint = e.Location;
        pictureBox2.Parent = this;
        pictureBox2.BringToFront();

    }

    private void pictureBox2_MouseMove(object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Left)
        {

            pictureBox2.Left += e.X - downPoint.X;
            pictureBox2.Top += e.Y - downPoint.Y;
        }
    }

    private void pictureBox2_MouseUp(object sender, MouseEventArgs e)
    {
        Control c = GetChildAtPoint(new Point(pictureBox2.Left - 1, pictureBox2.Top));

        if (c == null) c = this;
        Point newLoc = c.PointToClient(pictureBox2.Parent.PointToScreen(pictureBox2.Location));
        pictureBox2.Parent = c;
        pictureBox2.BackColor = Color.Transparent;
        pictureBox2.Location = newLoc;

        this.Refresh();
        pictureBox2.BringToFront();
    }

我能够将pictureBox2移动到任何地方并将其指定为父级，但我无法将其指定为pictureBox1作为其父级，因为它只检测groupBox2作为其父级。

任何帮助将不胜感激。谢谢。文森特

尝试将PictureBox1.BorderStyle属性设置为None。

删除图片框周围的白框？
