从表单 vb.net 更改打开的用户控件的 GroupControl 可见性

Question

我有一个 'UserControl' 在表格内打开，这个用户控件有一个 'GroupControl' 当用户单击表单上的按钮时，如何使 'GroupControl' 隐藏或可见使用 vb.net

Answer 1

试试这个：

在您的 UserControl 中添加一个程序来设置您的 GroupControl 的可见性：

 Public sub SetVisibility (V as boolean)
     YourGroupControl.visible=v
 End Sub

在你的表单中

   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

Answer 3

要简化，您可以使用：

MyParentForm.UserControlName1.GroupControlName.Visible = False

或

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

但最好的方法是创建一个属性，它允许像这样更改 UserControl Class 中 GroupControl 的可见属性 :

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