How to create the customer property of user control that will enable the user to assign string type variable in design time

我尝试过：

推荐答案

只需向控件添加属性：

Just add a property to the control:

public partial class MyUserControl : UserControl
    {
    public string MyProperty { get; set; }
    public MyUserControl()
        {
        InitializeComponent();
        }
    }

一旦你编译它，它就会添加到工具箱中。

将它放在你的表格和财产上将正常出现在物业窗格中。

Once you compile it, it will add to the toolbox.
Drop that on your form, and the property will appear in the Property Pane as normal.

我的问题是，在设计模式下，在安全级别的属性窗格中，而不是int值（0/1），我想分配int类型的公共变量说user_level

如果这就是你所需要的，那么当你提出问题时就要求这样做！ ：笑：



这很简单：使用枚举。

If that's what you need, then ask for that when you ask a question! :laugh:

It's simple: use an Enum.

public partial class MyUserControl : UserControl
    {
    public string MyProperty { get; set; }
    public enum SecurityLevels
        {
        User = 0,
        Admin = 1,
        }
    public SecurityLevels SecurityLevel { get; set; }
    public MyUserControl()
        {
        InitializeComponent();
        }
    }

除了答案1，您还可以添加属性，例如：

In addition to answer 1, you can also add attributes, example:

[Category("Appearance"), Description("Sets/Gets rotated text"), DefaultValue(typeof(string), ""), Bindable(true)]
public string RotatedText
{
    get
    {
        return (rotatedtextstring);
    }

    set
    {
        if (rotatedtextstring != value)
        {
            rotatedtextstring = value;
            this.Refresh();
        }
    }
}

这取自 RoundedButton 控件，参见示例这里： RoundedButton Control - 揭秘DrawArc [ ^ ]
