First, I should mention that I have DNN4 installed and running in my VS2005 test environment, and things seem to be working fine.

I created a new module, and it has two view controls: One to view a list, and one to view a detail. In defining the module, I have defined the list view without a key (it is to be the default view), and given a unique key name to the details view.

The list control works great, no problems accessing data or anything. But when I click on an entry, it is supposed to show the details control, but it does not. It only shows a blank page (except for skin and default stuff). If I define the "details" control to have no key and remove the list control, things seem to work: I see the details page but with the message I wrote saying there's a problem. Also, a breakpoint on LoadPage stops when there is no Key defined on the details page, but it does not break when I navigate there with a Key defined.

Does anyone have any suggestions? I've read most of what is out there, and I can't find anything wrong with my technique!

In the list, each item is a asp:HyperLink. The page with the module is on: http://localhost:4858/WWD/Home/SpeciesList/tabid/88/Default.aspx, and the page the hyperlinks point to is http://localhost:4858/WWD/Home/SpeciesList/tabid/88/ctl/SpeciesDetails/sid/3/Default.aspx. The highlighted shows the reference, which was gotten from: NavigateUrl='<%# DotNetNuke.Common.Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "SpeciesDetails", "sid="+ Eval("SpeciesID")) %>'

The module definition is included below.

<modules>
    <module>
    <friendlyname>WoodSpecies</friendlyname>
    <cachetime>0</cachetime>
    <controls>
        <control>
            <src>DesktopModules/WoodSpecies/ViewWoodSpeciesNames.ascx</src>
            <type>View</type>
            <helpurl></helpurl>
        </control>
        <control>
            <key>SpeciesDetails</key>
            <src>DesktopModules/WoodSpecies/ViewWoodSpeciesDetails.ascx</src>
            <type>View</type>
            <helpurl></helpurl>
        </control>
        <control>
            <key>Settings</key>
            <title>Wood Species Module Settings</title>
            <src>DesktopModules/WoodSpecies/Settings.ascx</src>
            <type>Edit</type>
            <helpurl></helpurl>
        </control>
    </controls>
    </module>
</modules>

Thank you very much. It works!

My module is generic, and the module itself did not need the moduleID, since the database entries were "factual" and not module-instance specific. It appears the ModuleID in the parameter list is being used by the NavigateURL or framework, even though I don't need it.

Another lesson learned...

I am not quite getting the NavigateURL syntax. I have a Gridview with a list of items and want to navigate to a form control to display item details. I have tried setting the grid column containing the link as follows:

<asp:HyperLink ID="hName" Runat="server" Text='<%# Bind("Name") %>' NavigateUrl='<%# DotNetNuke.Common.Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "HotelForm","mid="+ Cstr(ModuleId), "hotelid="+ Eval("HotelID")) %>' />
