[英]Change Text (translation) on other UserControl form, VB.NET Question
[英]change GroupControl visibility of opened usercontrol from the form vb.net
我有一个在窗体内打开的“ UserControl”,此usercontrol有一个“ GroupControl”,当用户使用vb.net单击存在于窗体上的按钮时,如何隐藏或显示此“ GroupControl”
尝试这个 :
在您的UserControl中添加一个过程,如何设置GroupControl的可见性:
Public sub SetVisibility (V as boolean)
YourGroupControl.visible=v
End Sub
以您的形式
Public Class Form1
Dim uc As New MyUserControl
Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Me.Controls.Add(uc)
uc.Dock()
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
uc.SetVisibility(False)
'NB :MyUserControl is name of your usercontrol
End Sub
End Class
在用户控件中:
Public Property GroupControlVisible() As Boolean
Get
Return Me.GroupControl1.Visible
End Get
Set(value As Boolean)
Me.GroupControl1.Visible = value
End Set
End Property
为了简化,您可以使用:
MyParentForm.UserControlName1.GroupControlName.Visible = False
要么
CType(MyParentForm.Controls("UserControlName").Controls("GroupControlName"), _
GroupControl).Visible = False
但是最好的方法是创建一个属性,该属性允许像这样在UserControl
类中更改GroupControl
的Visible属性:
Public Property GroupControlVisibility() As Boolean
Get
Return Me.GroupControlName.Visible
End Get
Set(value As Boolean)
Me.GroupControlName.Visible = value
End Set
End Property
