编译后，UserControl的文本消失在设计器中 [英] Text of UserControl dissappears in designer after compilation

问题描述

我的解决方案中发生了最奇怪的事情。
我有一个按钮，它是我自定义的。它继承了UserControl，其文本表示为该控件内的Label。

I have the wierdest thing going on in my solution. I have a button, which I customly made. It inherits UserControl, and its text is represented as a Label inside that control.

自然地，我希望覆盖按钮的文本以设置Label的文本：

Naturally, I wanted the button's text to be overridden to set the Label's text:

或者

    /// <summary>
    /// Gets or sets the text that appears in the button
    /// </summary>
    [Category("Appearance"), Description("Gets or sets the text on the button.")]
    [Browsable(true)]
    public override string Text
    {
        get
        {
            return base.Text;
        }
        set
        {
            base.Text = value;
            labelButtonText.Text = value;
        }
    }

Or

    /// <summary>
    /// Gets or sets the text that appears in the button
    /// </summary>
    [Category("Appearance"), Description("Gets or sets the text on the button.")]
    [Browsable(true)]
    public override string Text
    {
        get
        {
            return labelButtonText.Text ;
        }
        set
        {
            labelButtonText.Text = value;
        }
    }

无论使用哪种方法，当我在另一个UserControls / Forms，
在编译后消失在设计器中的文本消失。

Regardless of the method, when I use that button in another UserControls/Forms, the text I explicitly put inside in the designer dissappears after compilation.

我在 Button.designer.cs文件中签入，

I checked in the "Button.designer.cs" file, and there is no assignment of the text to null nor empty for neither the UserControl nor the Label.

EDIT ：此外，当我将设计器中的文本属性，不会在* .designer.cs文件中设置。

EDIT: Moreover, when I set the Text property in the designer, it does not set in the *.designer.cs file.

预先感谢。

推荐答案

是的，这是设计使然。 UserControl.Text属性如下所示：

Yes, this is by design. The UserControl.Text property looks like this:

[Browsable(false)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
[EditorBrowsable(EditorBrowsableState.Never)]
[Bindable(false)]
public override string Text
{
    get
    {
        return base.Text;
    }
    set
    {
        base.Text = value;
    }
}

您照顾了[Browsable]属性，但不是 [DesignerSerializationVisibility]。隐藏是使文本消失的原因。通过撤消所有属性来修复它：

You took care of the [Browsable] attribute but not the [DesignerSerializationVisibility]. Hidden is what makes the text disappear. Fix it by undo-ing all of the attributes:

    [Browsable(true)]
    [EditorBrowsable(EditorBrowsableState.Always)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    [Bindable(true)]
    public override string Text {
        // etc..
    }
