推荐答案

按照此示例进行操作，在这里我正在使用xml文件创建菜单.

Follow this example , here i am creating menu using xml file.

xml file-



<sitemap>

<sitemapnode url="Default.aspx" title="Home">

<sitemapnode title="Products" description="Our Products">

<sitemapnode url="Product1.aspx" title="My Products">

description="These are my products" />

<sitemapnode url="Product2.aspx" title="New Products">

description="Some new products " />

</sitemapnode>

<sitemapnode title="Services" description="Our Services">

<sitemapnode url="Service1.aspx" title="ASP.NET Consulting">

description="Best ASP.NET Consulting" />

<sitemapnode url="Service2.aspx" title="ASP.NET Training">

description="Best ASP.NET Training" />

</sitemapnode>

</sitemapnode>

</sitemapnode></sitemapnode></sitemapnode></sitemapnode></sitemap>

现在，使用此代码通过xml设计菜单.

Now use this code to design menu using xml.

private void CreateMenuWithXmlFile()

{

string path = @"C:\MyXmlFile.xml";

DataSet ds = new DataSet();

ds.ReadXml(path);

Menu menu = new Menu();

menu.MenuItemClick += new MenuEventHandler(menu_MenuItemClick);

for (int i = 0; i < ds.Tables.Count; i++)

{

MenuItem parentItem = new MenuItem((string)ds.Tables[i].TableName);

menu.Items.Add(parentItem);

for (int c = 0; c < ds.Tables[i].Columns.Count; c++)

{

MenuItem column = new MenuItem((string)ds.Tables[i].Columns[c].ColumnName);

menu.Items.Add(column);

for (int r = 0; r < ds.Tables[i].Rows.Count; r++)

{

MenuItem row = new MenuItem((string)ds.Tables[i].Rows[r][c].ToString());

parentItem.ChildItems.Add(row);

}

}

}

Panel1.Controls.Add(menu);

Panel1.DataBind();

}

您可以将菜单项绑定到站点地图并使用role属性.为此，您将需要在Web.Config中启用安全修整".这是最简单的方法.

另一个可行但不太理想的选项是使用loginview控件，该控件可以基于角色显示控件.这可能是最快(但灵活性/性能最低)的选项.您可以在此处找到指南:

You can bind the menu items to a site map and use the roles attribute. You will need to enable Security Trimming in your Web.Config to do this. This is the simplest way.

Another option that works, but is less ideal is to use the loginview control which can display controls based on role. This might be the quickest (but least flexible/performant) option. You can find a guide here:
