Hi All,

I'm looking for a code snippet to be used to navigate to a module on different page, I assume that:

- {{PageName}} to navigate is given but its TabId is not;

- {{ModuleNameToNaviagate}} is given but its ModuleId is not;

- {{ControlKeyToNavigate}} is given;

- there is just one module on target page.

I can use code snippet as published here:

http://adefwebserver.com/dotnetnukehelp/NavigateURL/Default.htm

but I still to find out how to get TabId by PageName, and ModuleId by ModuleName. Could you please advise?

Thank you.

Sorry, it didn't work - still can't navigate to a page with given name to have its certain module opened a certain (view) control. It is probably not possible at all? Please advise - below are code snippets, which almost work as required:

/// <summary>
/// Navigates to current module own view control
///  given this control's key <paramref name="controlKey"/>
/// </summary>
/// <param name="currentModuleInstance">Current module instance,
///    see <see cref="PortalModuleBase"/></param>
/// <param name="controlKey">A key of view control to navigate to</param>
public void NavigateToCurrentModuleViewControl(
    PortalModuleBase currentModuleInstance,
    string controlKey)
{
    int tabId = currentModuleInstance.TabId; ;
    string thisModuleIdAsAdditionalParameter =
            string.format("mid={0}", this.ModuleId);
    currentModuleInstance.Page.Response.Redirect(
        DotNetNuke.Common.Globals.NavigateURL(
         tabId,
         controlKey,
         thisModuleIdAsAdditionalParameter));
}

/// <summary>

/// </summary>
/// <param name="portalId">Portal Id</param>
/// <param name="tabName">Tab Name</param>
/// <returns>TabId if tabName belongs to an exiting page, -1 otherwise</returns>
/// <remarks>

/// </remarks>
public int GetTabIdByTabName(int portalId, string tabName)
{
    int tabId = -1;
    //?tabId = DotNetNuke.Entities.Tabs.TabController.GetTabByTabPath(portalId, tabName);
    List<DotNetNuke.Entities.Tabs.TabInfo> tabs = DotNetNuke.Entities.Tabs.TabController.GetPortalTabs(portalId, -1, false, false);
    foreach (DotNetNuke.Entities.Tabs.TabInfo tabInfo in tabs)
        if (string.Compare(tabInfo.TabName, tabName, true) == 0)
            return tabInfo.TabID;
    return tabId;
}

/// <summary>
/// Gets ModuleId by module friednly name
/// </summary>
/// <param name="moduleFriendlyName">Module Friendly name</param>
/// <returns>ModuleId if given module friendly name corresponds to an

public int GetModuleIdByFriendlyName(string moduleFriendlyName)
{
    //?DotNetNuke.Entities.Modules.Definitions.ModuleDefinitionInfo info =
    //  DotNetNuke.Entities.Modules.Definitions.ModuleDefinitionController.GetModuleDefinitionByFriendlyName
    //    (moduleFriendlyName);
    Dictionary<int, DotNetNuke.Entities.Modules.Definitions.ModuleDefinitionInfo> dictionary =
      DotNetNuke.Entities.Modules.Definitions.ModuleDefinitionController.GetModuleDefinitions();

    foreach (DotNetNuke.Entities.Modules.Definitions.ModuleDefinitionInfo info in dictionary.Values)
        if (string.Compare(info.FriendlyName, moduleFriendlyName, true) == 0)
            return info.DesktopModuleID;
   
    throw new ApplicationException
        (string.format("Can't get ModuleId for given module friednly name '{0}'",
          moduleFriendlyName));
}

public void NavigateToOtherTabModuleViewControl(

    string tabName,
    string moduleFriendlyName,
    string controlKey)
{
    int portalId = this.PortalId;
    int tabId = GetTabIdByTabName(portalId, tabName);
    int moduleId = GetModuleIdByFriendlyName(moduleFriendlyName);

    string moduleIdAsAdditionalParameter =
            string.format("mid={0}", moduleId);
    // it doesn't work -
    // currentModuleInstance.Page.Response.Redirect(

    //     moduleIdAsAdditionalParameter), true);
    currentModuleInstance.Page.Response.Redirect(

         tabId), true);
}

Thank you.

You're getting close to a solution . . .

I would suggest you set debugger breakpoints to examin the value of TabID and ModuleID returned from your two functions and compare with expected values.

It would appear that your function to return the TabID from TabName should work correctly. However, a more efficient approach would be to use the TabController.GetTabByName method.

However, your function to obtain the ModuleID from module friendly name is failing because it is returning the DesktopModuleID not the ModuleID. I would use ModuleController.GetTabModules to obtain the dictionary of ModuleInfo objects for the given TabID then iterate through the ModuleInfo objects to locate the desired ModuleName (not FriendlyName which can be changed by the host user). Note that if you are programming against DNN 5.x, you would use the newly added DesktopModule.ModuleName property of the ModuleInfo object.

Hope this helps!

The call to NavigateURL should return the proper URL for the Redirect provided that the TabID and ModuleID are correctly supplied.
