使用Visual Studio开发WINCC或FTView SE的.Net控件（二）

在上一篇文章末尾后记中记录了RA FTView SE控件事件的响应方法，我在后续制作控件的时候，发现事件参数的传递需要有特定的编写方式，记录一下： VS控件事件事件编写如下：

<DefaultEvent("MenuItemClick")>
Public Class KNavMenu
    Inherits TreeView

    Public Event MenuItemClick As EventHandler

    Private Sub ShowSelectedNode()
        Dim args As New ThresholdReachedEventArgs With {
            .nodeName = SelectedNode.Name,
            .nodePath = SelectedNode.FullPath,
            .nodeIndex = SelectedNode.ToolTipText
        }
        RaiseEvent MenuItemClick(SelectedNode, args)
    End Sub
End Class
Class ThresholdReachedEventArgs
    Inherits EventArgs
    Public Property nodeName As String
    Public Property nodePath As String
    Public Property nodeIndex As Integer
End Class
