Hello Guy''s
I Need a help it is easy to right person to solve it

现在我想在用户点击时打开Form1中的Form3来自Form2的按钮



Form1设置为Ismdicontainer = Talse



它是父类功能。



感谢希望任何人尽快帮助我..

等待示例代码，这有助于打开这样的表格



谢谢

推荐答案

这很简单，但最好不要按照你的想法去做。

因为Form1是Form2和Form3，它应该是唯一可以解决它们的形式 - 否则，所有三种形式的设计都被锁定在一起，并且维护它们变得更加困难。



所以你要做的是在Form2中创建一个事件（称之为ShowDetailsRequest或类似的），它在Form1中处理。事件处理程序比通过公共属性从Form2获取所需信息后打开Form3（或者不是，如果它有不同的方式来显示信息）。

这很容易做到：有一个在这里查看添加活动的简单代码片段 [ ^ ] - 您需要的代码位于Tip的顶部，其余部分仅描述了如何更容易地创建它们。

That is fairly simple to do, but it''s best not to do it in the way you think.
Because Form1 is the parent of both Form2 and Form3, it should be the only form which konws about them both - otherwise, the design of all three forms is locked together, and it becomes a lot harder to maintain them.

So what you do is to create an event in Form2 (call it ShowDetailsRequest or similar) which is Handled in Form1. The event handler than opens Form3 (or not, if it has a different way to display the information) after getting what information it needs from Form2 via public properties.
This is really easy to do: have a look here A simple code snippet to add an event[^] - the code you need is in the top of the Tip, the rest just describes how to make it easier to create them.
