從形式vb.net更改打開的用戶控件的GroupControl可見性

Question

我有一個在窗體內打開的“ UserControl”，此usercontrol有一個“ GroupControl”，當用戶使用vb.net單擊存在於窗體上的按鈕時，如何隱藏或顯示此“ GroupControl”

Answer 1

嘗試這個 ：

在您的UserControl中添加一個過程，如何設置GroupControl的可見性：

 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

Answer 2

在用戶控件中：

Public Property GroupControlVisible() As Boolean
    Get
        Return Me.GroupControl1.Visible
    End Get
    Set(value As Boolean)
        Me.GroupControl1.Visible = value
    End Set
End Property

Answer 3

為了簡化，您可以使用：

MyParentForm.UserControlName1.GroupControlName.Visible = False

要么

CType(MyParentForm.Controls("UserControlName").Controls("GroupControlName"), _
                GroupControl).Visible = False

但是最好的方法是創建一個屬性，該屬性允許像這樣在UserControl類中更改GroupControl的Visible屬性：

Public Property GroupControlVisibility() As Boolean
    Get
        Return Me.GroupControlName.Visible
    End Get
    Set(value As Boolean)
        Me.GroupControlName.Visible = value
    End Set
End Property
