问大家一个问题，我有一个WinForm窗体中,容体中有一个tablelayoutpanel控件，有一个button控件，button可以在窗体上移动，让button移动到tablelayoutpanel的工作区内，就被自动吸附到表格里 private void button1_MouseDown(object sender, MouseEventArgs e)
{
p = new Point(e.X, e.Y);
} private void button1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this.button1.Location = new Point(e.X - p.X + this.button1.Left, e.Y - p.Y + this.button1.Top);
if (this.button1.Left < 0 || this.button1.Right > this.Width || this.button1.Top < 0 || this.button1.Bottom > this.Height)
{
this.button1.Location = new Point(0, 0);
}
}
else
{
this.button1.Cursor = Cursors.Hand;
}
}以上环境在vs2005
{
p = new Point(e.X, e.Y);
} private void button1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this.button1.Location = new Point(e.X - p.X + this.button1.Left, e.Y - p.Y + this.button1.Top);
if (this.button1.Left < 0 || this.button1.Right > this.Width || this.button1.Top < 0 || this.button1.Bottom > this.Height)
{
this.button1.Location = new Point(0, 0);
}
}
else
{
this.button1.Cursor = Cursors.Hand;
}

<!--
