Question

我的情况是我正在构建动态表单，单击按钮需要生成几个新控件。但是，重要的是每组控件只能看到该组中的控件，而不是其他控件。所以，我试图创建一个单独的类来保存控件，我希望每次单击都能创建这个类的新实例。

我的问题是如何让它们显示在表单上？

这是包含控件的类：

public class CrmCustomerSearchRow 
{
    public SimpleButton Remove = new SimpleButton();
    public LookUpEdit AttributeList = new LookUpEdit();
    public LookUpEdit ConditionalList = new LookUpEdit();
    public LookUpEdit EnumerableOptions = new LookUpEdit();
    public TextEdit NumericEntry = new TextEdit();
    private readonly StyleController _style = new StyleController();
    private CustomerSearchController _controller = new CustomerSearchController();

    public CrmCustomerSearchRow(int rowX, int rowY, CustomerSearchController control) : this(rowX, rowY, control, false){}

    public CrmCustomerSearchRow(int rowX, int rowY, CustomerSearchController control, bool firstGo)
    {
        //Initializers
        _controller = control;
        Remove = new SimpleButton()
            {
                Enabled = !firstGo,
                Image = Properties.Resources._001_02,
                Location = new System.Drawing.Point(rowX, rowY),
                Name = "simpleButtonRemove",
                Size = new System.Drawing.Size(34, 30),
                StyleController = _style
            };
        AttributeList = new LookUpEdit()
            {
                Location = new System.Drawing.Point(Remove.Location.X + Remove.Width + 4, rowY),
                Name = "lookUpEditAttributeList",
                Size = new System.Drawing.Size(102, 20),
                StyleController = _style
            };
        AttributeList.Properties.Buttons.AddRange(new[]
            {
                new DevExpress.XtraEditors.Controls.EditorButton(
                                                      DevExpress.XtraEditors.Controls.ButtonPredefines.Combo)
            });
        ConditionalList = new LookUpEdit()
            {

                Location = new System.Drawing.Point(AttributeList.Location.X + AttributeList.Width + 4, rowY),
                Name = "lookUpEditConditionalList",
                Size = new System.Drawing.Size(50, 20),
                StyleController = _style
            };
        ConditionalList.Properties.Buttons.AddRange(new[]
            {
                new DevExpress.XtraEditors.Controls.EditorButton(
                                                        DevExpress.XtraEditors.Controls.ButtonPredefines.Combo)
            });
        EnumerableOptions = new LookUpEdit()
            {
                Location = new System.Drawing.Point(ConditionalList.Location.X + ConditionalList.Width + 4, rowY),
                Enabled = false,
                Name = "lookUpEditEnumerableOptions",
                Size = new System.Drawing.Size(91, 20)
            };
        ConditionalList.Properties.Buttons.AddRange(new[]
            {
                new DevExpress.XtraEditors.Controls.EditorButton(
                                                        DevExpress.XtraEditors.Controls.ButtonPredefines.Combo)
            });
        //Datastuffs
        AttributeList.Properties.DataSource = _controller.PropertyTypes;
        AttributeList.Properties.ValueMember = "AttributeTypeGuid";
        AttributeList.Properties.DisplayMember = "AttributeTypeName";
        //Event Handlers
        Remove.Click += Remove_Click;
        AttributeList.EditValueChanged += AttributeList_EditValueChanged;
        //Default Visibility and Enabledness
        ConditionalList.Enabled = false;
        EnumerableOptions.Visible = false;
        NumericEntry.Visible = false;
    }

这是尝试将它们添加到表单中：

        private void simpleButtonAddTemplate_Click(object sender, EventArgs e)
    {
        var oldX = int.Parse(simpleButtonAddTemplate.Location.X.ToString(CultureInfo.InvariantCulture));
        var oldY = int.Parse(simpleButtonAddTemplate.Location.Y.ToString(CultureInfo.InvariantCulture));
        var newX = oldX + int.Parse(simpleButtonAddTemplate.Size.Height.ToString(CultureInfo.InvariantCulture)) + 4;
        var newY = oldY;
        Rows.Add(
            new CrmCustomerSearchRow(oldX, oldY, _controller));
        simpleButtonAddTemplate.Location = new Point(newX, newY);

    }

您要找的是UserControl。这是一种定义用户定义控件的方法，该控件由许多其他控件组成，并具有自己的复合功能。让您的自定义类扩展UserControl而不仅仅是一个独立的类。（你也可能想通过VS创建一个UserControl，因为它可以帮助你，而不是让你手动完成所有事情。）

完成后，您只需创建用户控件的实例并将其添加到表单中;作为一个控制本身，这将是完全有效的。

如何在窗体上显示单独类中包含的控件？
