主题：配置栏上的控件如何获取焦点

菜单没有设置焦点的功能。

除非嵌入额外的菜单控件，如

Dim C As C1Ribbon.C1Ribbon  = Ctype(BaseMainForm.controls("C1Ribbon1"),C1Ribbon.C1Ribbon )
Dim a = new windows.forms.textbox
a.text = "123"
Dim b As New C1Ribbon.RibbonControlHost(a)
b.name = "自定义项1"
b.width = 300
c.ConfigToolBar.Items.Add(b)

vars("a") = a

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

vars("a").selectall
vars("a").Select
