I have tried : ParentForm.ControlBox = false;
我试过了:ParentForm.ControlBox = false;
... but it doesn't seem to work ... the ControlBox is still enabled!
...但它似乎不起作用...... ControlBox仍然启用!
Any ideas?
/I don't want to use the Win32 interop method to disable the 'X'. Disabling the ControlBox is fine.
/我不想使用Win32互操作方法来禁用'X'。禁用ControlBox很好。
2 个解决方案
#1
ParentForm.ControlBox = false, should work
ParentForm.ControlBox = false,应该可以工作
In C# just add
在C#中添加
protected override void OnClosing(CancelEventArgs e)
{
e.Cancel = true;
}
this will not disable the ControlBox but will prevent window from closing
这不会禁用ControlBox但会阻止窗口关闭
#2
Have you tried using the FindForm() method instead? It seems as if the ParentForm property can return a null reference (not sure under which circumstances yet, though). It did for me now when I created an empty UserControl and added it to a form. Disabling the ControlBox through FindForm worked well though.
您是否尝试过使用FindForm()方法?似乎ParentForm属性可以返回一个空引用(但不确定在哪种情况下)。当我创建一个空的UserControl并将其添加到表单时,它现在为我做了。通过FindForm禁用ControlBox虽然运行良好。
