Question

我已经根据鼠标是否在组件内部显示并隐藏了一个按钮（btnImageRemove），但是当我点击该按钮时，事件不会触发。

Private Sub btnImageRemove_Click(sender As Object, e As EventArgs) Handles btnImageRemove.Click
    lblAvatar.Image = Nothing
    lblAvatar.Tag = Nothing
End Sub

Private Sub lblAvatar_MouseLeave(sender As Object, e As EventArgs) Handles lblAvatar.MouseLeave
    btnImageRemove.Visible = False
End Sub

Private Sub lblAvatar_MouseEnter(sender As Object, e As EventArgs) Handles lblAvatar.MouseEnter
    btnImageRemove.Visible = True
    btnImageRemove.BringToFront()
End Sub

Private Sub btnImageRemove_MouseClick(sender As Object, e As MouseEventArgs) Handles btnImageRemove.MouseClick
    lblAvatar.Image = Nothing
    lblAvatar.Tag = Nothing
End Sub

我已尝试按钮上的所有点击和鼠标点击事件，以及占据其区域的所有组件，但我无法为该按钮触发事件

缩小范围会导致更多：我已经缩小到如果我在运行时添加任何东西以显示/隐藏按钮，在另一个事件中，按钮不会触发单击事件，也不会变为橙色（默认的dotnetbar按钮操作）

mouseenter使按钮可见但按钮单击事件则不会触发
