获取和更新PreferredSize属性的值

Question

下午好!

A visual example if AutoScroll = true;

A visual example if AutoScroll = false;

请告诉我，如果Panel.AutoScroll = false，如何获取/计算/或更新Panel.PreferredSize属性值？

Answer 1

private void flp_Container_ControlAdded(object sender, ControlEventArgs e) {
    flp_Container.VerticalScroll.Maximum = flp_Container.GetPreferredSize(flp_Container.Size).Height - flp_Container.Size.Height;
    VScrolBar1.Maximum = flp_Container.VerticalScroll.Maximum;           
}
