在自定义控件中获取父表单名称 [英] Get parent form name in custom control

问题描述

您好，专家，

如何在自定义控件中获取父表单名称.

例如:如果自定义控件以mytest形式放置在选项卡控件中，则我在自定义控件中的预期结果应为mytest.

我尝试使用自定义控件提供的以下选项
1)this.parent.Findform():如果将自定义控件放置在容器中，即tabcontrol，groupbox等中，则返回null值(如果将自定义控件直接放置在窗体中，则此方法无效).
2)this.FindForm():返回空值
3)this.Parent.Parent:未预期的结果
注意:在用户控件中，有this.parentform选项，它返回表单名称.自定义控件中没有相同的功能

感谢在这方面获得帮助.

Hi Experts,

How to get the parent form name in custom control.

For ex: If the custom control is placed within tab control in mytest form, then my expected result in custom control shall be mytest.

I tried using following options available with custom control
1) this.parent.Findform() : returning null value (this works if the custom control is placed in form directly) fails if the custom control is placed in container i.e in tabcontrol,groupbox etc.
2) this.FindForm() : returning null value
3) this.Parent.Parent: not expected result
Note: In usercontrol there is option available as this.parentform which returns form name. same is not available in custom control

Appreciate to get help in this regard.

我遇到了类似的问题，但是我不记得确切的解决方法.您应该能够在本文和随附的代码中找到线索(它在VB中，但这只是次要的细节，不应更改任何内容):

脏按钮 [

I had a similar problem, but I don''t remember exactly how I solved it. You should be able to find a clue in this article and the accompanying code (it''s in VB, but that''s a minor detail that shouldn''t change anything):

Dirty Button[^]

It works for me at least both when the control is placed directly on the form and in a groupbox/tab control

I could be wrong, but I think actually that this.FindForm() SHOULD return the correct form object.

I just checked my code, and I did indeed use this.FindForm() to get the correct result. Don''t understand why iut doesn''t work for you?!?!? [/EDIT]

您需要使用反射来获取类名.否则，您最好的办法就是获取表单标题或类似的标题.

You need to use reflection to get class names. Otherwise, the best you can do is to get the form title or something like that.
