Mdichild表格没有得到关注

问题描述

我有一个MDI表单，其中包含一个树（左侧停靠），用作打开MDIChild表单的菜单。当我单击树的节点（在 NodeMouseClick 事件中）时，将打开一个新的MDIChild表单。问题是它没有得到关注。焦点总是留在树上。 MDIChild表单没有标题，并且在父MDI表单中最大化。



我尝试过：



我试过在MDIChild表格上使用.Focus，Activate，BringToFront而没有任何运气。



是否有解决方案这个问题？使用.NET 4.0.3。

解决方案

I have an MDI form which contains a tree (docked left) which acts as a menu for opening MDIChild forms. When i click on a node of the tree (in NodeMouseClick event), a new MDIChild form is opened. The problem is that it does not receive the focus. The focus always remains on the tree. The MDIChild form does not have a Title and is maximized within the parent MDI form.

What I have tried:

I have tried using .Focus, Activate, BringToFront on the MDIChild form without any luck.

Is there a solution to this problem? Using .NET 4.0.3.
