如何将winform输入屏幕顶部 [英] how to oder a winform to top of screen

问题描述

我有一个c#win窗体程序，它包含midi父窗体和子窗体，我想在mdi子窗体中调用窗体
例如:
mdi子窗体是frmCompany.cs，当我在文本框上按f2功能键时，该窗体包含名为comCode的文本框，它应该会出现另一个调用frmsearch的窗体，但是在调用frmsearch窗体后，它应该是最高级的窗体，应该在关闭新调用的frmsearch表单之前，不允许访问以前的表单

如何执行此任务?
请帮助我

推荐答案

使用InstanceName.ShowDialog()使其保持模态，并且不要使此表单成为MDI子级.

Use InstanceName.ShowDialog() to keep it modal, and don''t make this form MDI child.
