WPF自定义控件：如何将类别“文本”分配给属性？

Question

Some native WPF controls have a property category "Text" under which they are listed in the properties inspector, when "Arrange by: Category" is active. But when I try to set this category for a property of my WPF custom control using

[Category("Text")]

it does not work. The property does not appear in any category. (Tested with VS 2015.)

This is in accordance with the fact that System.ComponentModel.CategoryAttribute does not include a Text category.

But how is it then possible to associate a property with the Text category?

Edit: For clarification, here is the relevant part of the implementation of the property in the original code:

using System;
using System.ComponentModel;
using System.Globalization;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Controls.Primitives;
using System.Windows.Input;
using System.Windows.Media;

...

public static readonly DependencyProperty IsReadOnlyProperty;

...

[Browsable(true)]
[Category("Text")]
[Description("Gets or sets a value that indicates whether the text editing control is read-only to a user interacting with the control.")]
public bool IsReadOnly
{
  get { return (bool)GetValue(IsReadOnlyProperty); }
  set { SetValue(IsReadOnlyProperty, value); }
}

First make sure you are using a Dependency Property. If not try typing in dependencyproperty and hit tab (or enter). Then define its type and name.

Then you may find these lines of code and add your attribute like this:

[Description("Your Description"), Category("Text")]
public string PropName {
     get { return (string)GetValue(PropNameProperty); }
     set { SetValue(PropNameProperty, value); 
}
