Disable radio buttons by default
提问by user1532468
I am trying to find a way to make radio buttons disabled by default. I have managed to disable them inside my event handler for CheckedChangedbut that only works when action is taken by the user. How do I disable the control by default?
我试图找到一种方法来默认禁用单选按钮。我已经设法在我的事件处理程序中禁用它们，CheckedChanged但这仅在用户采取行动时才有效。如何默认禁用控件？
Private Sub rdoCustomer_CheckedChanged(ByVal sender As Object,
ByVal e As EventArgs) _
Handles rdoCustomer.CheckChanged, rdoDepartment.CheckedChanged
rdoCustomer.Enabled = False
rdoCustomer.Checked = True
rdoDepartment.Enabled = False
End Sub

To set anything "by default", just write it in the Form Load Event. Sample:
要“默认”设置任何内容，只需将其写入Form Load Event. 样本：
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
rdoCustomer.Enabled = False
rdoCustomer.Checked = False
rdoDepartment.Enabled = False
rdoDepartment.Checked = False
End Sub
Or, alternatively, via properties of the given control(s) in "Design View". All this by assuming that the controls weren't created at runtime (in that case, right after being created).
或者，或者，通过“设计视图”中给定控件的属性。所有这一切都是假设控件不是在运行时创建的（在这种情况下，是在创建之后）。
