Ch 7, p249 SiteMapDataSource

RAFish0404 · November 6th, 2016, 08:54 PM

I've been working my way through the exercises and have been reasonably successful. When I hit Step 8 on p249, Press F4 and change the ShowStarting Node property to False, the text indicates that I should see the designer update with the child menus: Home, Reviews, About and Login, as shown in Fig 7.5. That just doesn't happen!

The error I receive is:

The DataSourceID of "Menu1" must be the ID of a control of type IHeirarchalDataSource. A control with the ID 'SiteMapDataSource1' could not be found.

Can you suggest what I'm doing wrong?

Thanks

Hi there,

Can you post the full code for the page? When you post the code, can you please paste it in Notepad first to remove color coding and then use the forum editor's Code toolbar button to wrap your code in code tags. Otherwise, this forum messes up the code.

Cheers,

Imar

After a couple tries I just shut VS down and restarted my computer. When I reopened the site project, everything was wired correctly and the menu worked as it was designed. I am using VS 2015 Professional.

Thank you for your prompt reply. The code is shown below for completeness.

<nav>
<asp:Menu ID="Menu1" runat="server" CssClass="MainMenu" DataSourceID="SiteMapDataSource1" Orientation="Horizontal" StaticEnableDefaultPopOutImage="False"></asp:Menu>
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ShowExpandCollapse="False">
<LevelStyles>
<asp:TreeNodeStyle CssClass="FirstLevelMenuItems" />
</LevelStyles>
</asp:TreeView>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" />
</nav>

Odd, sounds like a bug in VS. Glad it's working now though.

I'm having a recurring problem with getting changes I make to the site to take effect. I just went through the exercise on p252, entered all the code by hand and pressed Ctrl-F5. The menu items remained unchanged. I tried to Build the Website, and Rebuild the Website. I tried copying the code from the downloaded source files.

I have warnings about section#MainContent and aside#Sidebar being overqualified, the universal selector(*) being slow and the !important qualifier. The site builds correctly but does not incorporate the style sheet changes.

So what an I doing wrong?

Hi there,

Can you post the relevant code for the master page? Also, could it be a cache issue? Try reloading with Ctrl+F5 and see if that fixes the issue.

Cheers,
