添加按钮以控制属性 [英] Add a button to control properties

问题描述

我正在制作自己的用户控件，并有2个问题
1.我想在默认属性列表上添加一个按钮，并且我想在单击该按钮时打开模式窗体，
2.我想将控件属性归为一类(属性Category(...)不起作用，因为我发现它仅适用于我添加的属性网格).

这是完全可能的，但并不容易；您将写几件事以允许在PropertyGrid中进行自定义编辑.我认为模态形式不是一个好主意，因为您可以通过提供自定义的就地编辑器来做得更好.但是，也可以使用模式形式:内联编辑器将是您想要的按钮；然后此按钮将显示您的模态形式.

我试图在此处描述有关此主题的路线图:如何单击PropertyGrid时获得响应 [ ^ ].

同样，这并不容易，所以对不起我无法为您的案例专门开发代码.这将远远超出CodeProject问题与答案的格式.您可以找到主意，转到我在答案"中列出的类型的帮助页面，并编写自己的代码，是否以及何时遇到任何其他问题，请提出另一个问题.

Hi,
i''m making my own user control and have 2 questions
1. i want to add a button on default properties list and i want to open a modal form when that button is clicked,
2. i want to group my control properties in one category (the attribute Category(...) doesn''t work, as i found it works only with property grid added by me)

解决方案

This is quite possible but not easy at all; you''ll to write several things to allow custom edit in the PropertyGrid. I think modal form is not a good idea as you can do much better by providing a custom in-place editor. However, a modal form is also possible: you in-line editor will be the button you want; and this button will show your modal form.

I tried to describe a road map on this topic here: How to get response when click PropertyGrid[^].

Again, this is not easy, so I''m sorry I cannot afford developing code specially for your case. It would be far beyond the format of CodeProject Questions-and-Answers. You can get the idea, go to help pages on the types I list in my Answer and write your own code, ask another question if and when you face any problems.

Good luck,

To achieve your aims you will probably have to write a UITypeEditor[^] and one or more ControlDesigners or one of its descendants and quite possibly one or more TypeConverters. From your description possibly an ExpandableObjectConverter[^].

Here is a link to an example that uses most of these.[^]

I thought something about this

<pre lang="cs">public Sometype PropertyName
{
   get
   {
      return SomeValue;
   }
   set
   {
     (new Form()).ShowDialog();
   }
}
</pre>
