asp.net - 更改 radmenu 点击事件

Question

您好，在母版页中设置了一个 rad 菜单，并在其中添加了所有 url/链接。

我正在尝试从 D 后面的 aspx 页面代码中更改两个 radMenuitems 导航链接）用 javascript 点击事件替换链接。E) 当你点击然后触发 vb.net void click 事件

谢谢

Protected Sub Page_Load(sender As Object, e As EventArgs)

    Dim rmenu As RadMenu = DirectCast(Master.FindControl("mymenu"), RadMenu)
    Dim D As RadMenuItem = DirectCast(rmenu.FindControl("dogs"), RadMenuItem)
    Dim E As RadMenuItem = DirectCast(rmenu.FindControl("cats"), RadMenuItem)


    D.NavigateUrl = nothing
    E.NavigateUrl = nothing


    D.click = "alert('you clicked on dogs')"
    E.click = Button1_Click

End Sub


Protected Sub Button1_Click(sender As Object, e As EventArgs)
    'do this for cats only
End Sub
