问题：

asp:Menu 在Safari浏览器中显示不正常。

解决方法一：（App_Browsers）

Step1: Add App_Browser Folder in application

          right click on project add ASP.Net Folder - App_Browsers

          right click on  App_Browsers -- Add new item  --- Browser File  ( with name Safari.browser )

         Add this section in Safari.browser file and save the file.

<browsers>

  <browser refID="safari1plus">

    <capabilities>

      <capability name="xml" value="true" />

    </capabilities>

    <controlAdapters>

      <adapter controlType="System.Web.UI.WebControls.Menu" adapterType="" />

    </controlAdapters>

  </browser>

</browsers>

解决方法二：（不适用于Master Page）

You could also put it in the preint event...

Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit

        If InStr(Request.ServerVariables("http_user_agent"), "Safari") Then

            Page.ClientTarget = "uplevel"

        End If

    End Sub

解决方法三：（使用基类PageBase）

Rather than repeat  the same code on every page, I have created a new class called PageBase

public class PageBase: Page { public PageBase() { } protected void Page_PreInit(object sender, EventArgs e) { if (Request.ServerVariables["http_user_agent"].IndexOf("Safari", StringComparison.CurrentCultureIgnoreCase) != -1) Page.ClientTarget = "uplevel"; } }

and then changed all my ChildPages so that they inherit from PageBase, instead of System.Web.UI.Page
