I would like make the Option Panel

For the Application's design, there is a treeview and a Panel in winform like this

-----------------
TreeView

- Item 1
- Sub Item1
- Sub_Sub_Item1
- Sub_Sub_Item2
- Sub Item2
- Item 2
- Item 3
-----------------

Panel

-----------------

User Select the Nodes of Treeview and a corresponding panel show on the panel

User Set the value on the panel like textbox, datagridview, controls..

Also by setting the values on the panel, nodes of Treeview can be added.

What I have tried:

I placed

winform
Usercontrol corresponding to Nodes

but I couldn't control winform from Usercontrol.

Thing I'd like to know is that is it right approach or not.

Please advice me on the efficient way.

推荐答案

您不能从UserControl控制窗体 - 您可以在UserControl中引发窗体可以处理的事件以进行更新，就像TextBox引发TextChanged事件以告诉其父窗体它可以验证新数据一样to。

创建事件非常简单：添加活动的简单代码段 [ ^ ]显示代码（并提供自动化方法）。

You don't control a Form from a UserControl - you raise events in the UserControl which the Form can handle to update itself, just as a TextBox raises a TextChanged event to tell its parent Form that it can validate the new data is it wants to.
Creating events is pretty simple: A Simple Code Snippet to Add an Event[^] shows the code (and provides a way to automate it).
