Menu control Databinding problem using StaticItemTemplate

[Andrew Jocelyn]

Hi

How do add custom attributes to a System.Web.UI.WebControls.MenuItem in a
StaticItemTemplate which I have saved in my
SiteMapDataSource file? e.g.

<siteMapNode title="stuff" id="myid">

protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
{
string id = ((SiteMapNode)e.Item.DataItem)["id"];
if (id != null)
Trace.Write(id);
// add the attribute to the MenuItem
}

I can't see how you can do it with the Menu control. Do I have any other
options which are not too much work to implement?

Thanks
Andrew

Hi Andrew,

As for adding custom attributes to ASP.NET 2.0 Menu control, it is limited
by the following things:

** the <MenuItem> tag in Menu control is not sub controls, they're just
some property tag which is not directly constructed as a sub control at
runtime, there fore you can not add attributes into "MenuItem" class
instance

** so far the Menu control do not let you directly access the underlying
created MenuItem's actual control instance

One way for you to perform customization on the MenuItem(using template) is
add your data binding expression with custom functions. e.g.

=======
<StaticItemTemplate>
<%# CallYourCustomFunctionHere( params....) %>
</StaticItemTemplate>
=========

You can pass "Container" or "Container.DataItem" into your c ustom function
so as to determine the value to return in the custom function. How do you
think?

Sincerely,

Hi Steven

When I pass a Container.DataItem it's always a MenuItem object. I cannot get
the underlying object from the SiteMapDataSource. Is this correct? I can't
get any additional information from the web.sitemap file. Any ideas?

<asp:Menu ID="Menu1" runat="server" DataSourceID="SiteMapDataSource1">
<StaticItemTemplate>
<%# GetMenuItem(Container.DataItem) %>
</StaticItemTemplate>
</asp:Menu>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server"
ShowStartingNode="false" />

Thanks
Andrew

Hi Andrew,

Yes, it's a pity that the MenuItem class is a sealed class that can not
extend(I previously handled some issue about TreeView control and its
TreeNode class can be derived).

Currently, based on my research, one means to provide additional data would
be using the "Value" property of the MenuItem, do you think it posible that
you bind all the information together (through some separator char) into
the single "Value" property. And in your template, you can use some helper
function to parse those mutiple properties out?
