构建具有多个视图的C#.NET Windows应用程序

创建一堆重叠的面板是设计时的噩梦.

我建议在单独的选项卡上使用每个"视图"的选项卡控件,然后在运行时选择正确的选项卡.您可以通过在表单的Load事件中放置类似的内容来避免显示选项卡标题:

tabControl1.Top = tabControl1.Top - tabControl1.ItemSize.Height;
tabControl1.Height = tabControl1.Height + tabControl1.ItemSize.Height;
tabControl1.Region = new Region(new RectangleF(tabPage1.Left, tabPage1.Top, tabPage1.Width, tabPage1.Height + tabControl1.ItemSize.Height));

我所做的是建立一个面板,您的不同视图将位于主窗体上.然后为您的不同视图创建用户控件.

然后当我想在'view'之间切换时,你将它停靠在主窗体上的Panel ..代码看起来有点像这样.

我喜欢这个,因为你可以重复使用你的视图,就像你想在选项卡中打开一个视图,你可以将用户控件停靠在标签页中..甚至从tabpage而不是usercontrol继承,使事情变得更加通用

public partial class MainForm : Form
{
    public enum FormViews
    {
        A, B
    }
    private MyViewA viewA; //user control with view a on it 
    private MyViewB viewB; //user control with view b on it

    private FormViews _formView;
    public FormViews FormView
    {
        get
        {
            return _formView;
        }
        set
        {
            _formView = value;
            OnFormViewChanged(_formView);
        }
    }
    protected virtual void OnFormViewChanged(FormViews view)
    {
        //contentPanel is just a System.Windows.Forms.Panel docked to fill the form
        switch (view)
        {
            case FormViews.A:
                if (viewA != null) viewA = new MyViewA();
                //extension method, you could use a static function.
                this.contentPanel.DockControl(viewA); 
                break;
            case FormViews.B:
                if (viewB != null) viewB = new MyViewB();
                this.contentPanel.DockControl(viewB);
                break;
        }
    }

    public MainForm()
    {

        InitializeComponent();
        FormView = FormViews.A; //simply change views like this
    }
}

public static class PanelExtensions
{
    public static void DockControl(this Panel thisControl, Control controlToDock)
    {
        thisControl.Controls.Clear();
        thisControl.Controls.Add(controlToDock);
        controlToDock.Dock = DockStyle.Fill;
    }
}
