Lets imagine, that we have some catalog, let it be the goods catalog. You have top level categories and many subcategories for them and so on deeper. The whole menu can be of any deep.Of course I don't want to hardcode this catalog, I want to load its structure from a remote server (REST API for instance), so that I could change it any time wothout posting changes to apps
I am using React-navigation (if it makes any sense). How it is usually done?(1) Should I somehow create one page and pass there some parameters, or (2) should I create many distinct pages.In the first case (1) I can't even imagine, how can I pass new parameters to the same page again and again in such a way that each time there would be a new title in header of this page and a new submenu structure to be displayed.The second way (2) seems rather complex to me and is not the best idea... I suppose.What are best practices?enter image description here

Sorry if my question is silly but I'm new to DNN/2sxc, I've spent the whole day trying to figure this with no success..
I have two instances of the same app, one in the home page and the other on its own page, each one must have its own view template (I use Razor).
My problem is I cannot figure a way to make the two apps read the same data, so every add/edit/remove/re-sort in one of them will be reflected to the other, currently each app has its own data and therefore they are unusable in my case.
I've tried to use a 'EntityTypeFilter' inside a 'Data Query' and use it in both views (as in the News-Simple demo video), it worked and gave me all the items in the two views, but another two problems come with this solution:
1- now I'm unable to use the toolbar to (add/remove/reorder,.. etc) any of the items , as you can see in this image, which is a show-stopper for me,
note: this is the toolbar I use:
#foreach(var item in AsDynamic(Data["Default"]))
{
...
#Edit.Toolbar(target: item, actions: "new,edit,replace,remove,moveup,movedown,instance-list")
2- the 'Content Demo Item' is also visible in the list, but it is not that important since I can delete it and use one of the real data items as a demo item.
I appreciate any kind of help.
Thank you.
So the first thing you should know is the difference when using content-items as data (to query, etc.) and when using it as assigned-items (where each module-instance has a subset of items). Here's the blog that should help you understand the difference: http://2sxc.org/en/blog/post/12-differences-when-templating-data-instead-of-content
So when you want the "manually and easily control the exact items displayed, their ordering etc." you want to use the "content-assigned-to-instance" which also gives you the simple add, delete buttons, as these don't really delete anything, but just remove the assignment from the module-instance.
Now your case is a bit special, in that you want to re-use the exact same set in another module-instance. There are a few ways you can do this:
Same View
if it's exactly the same view etc. just duplicate the module using DNN-features (the add-existing-module-to-another page)
different view
if it's a different view (maybe more compact, etc.) you again have multiple options. The first is to mirror / duplicate using the dnn-feature, and just put an if-im-on-this-page-then-show-differently or inject another CSS. That's probably the easiest without any dev-know-how.
The harder, but possibly nicer way, is to actually to use a new template, and tell it to retrieve the items in the way they are configured in the other module - let's say module 1 is the original, module 2 has a different template wanting to access the items of module 1 in exactly the same order as given in 1. They way to do this is simple, but requires a few lines of C# code in Module 2.
You need to create a new ModuleDataSource (https://2sxc.org/en/Docs/Feature/feature/4542) object and tell it that it's from Module 1. If you've never done this, it's basically that your code can create a query just like the visual designer, but you have more control - see the wiki https://github.com/2sic/2sxc/wiki/DotNet-DataSources-All. The Module-Data-Source in the visual-query-designer doesn't allow you to "switch" modules (a advanced setting we may add in the future) but the object has a ModuleId property which you can set before accessing the data, making it "switch" to that Module. here's the Pseudo code in your Module#2 razor...
var otherModData = CreateSource<ModuleDataSource>();
otherModData.ModuleId = 1;
foreach(var itm in AsDynamic(otherModData["Default"])) {
...
}
That should do it :)
React router has very cool feature: if you have a list of items (Instagram for example) and if you click on one item, content opens in modal/overlay but if you copy-paste the link to new tab/window or share the link with a friend for example, it opens in its own page.
I would love to use this feature but I need to find a custom solution..
My posts are very data heavy
I've split posts data into 2 tables in database
1st is very lightweight containing essential data: 4-5 columns
2nd table is very heave, ~30 columns
When user uses search filter, list updates only with data from 1st table
If user clicks on post, it will open in a modal/overlay
I will recycle the data I already have (from 1st table) and also get rest of the data from 2nd table
However, when user shares the link or opens it in new tab/page, data from 1st table is not present. I would need to integrate a conditional logic:
If post opens in list view (modal/overlay), only get additinal 2nd table data
If it's opened in a new tab/window in its own page, get all the data, 1st table included
How could I integrate this with React router? Has anyone already tried it? This would also allow to use different layout/components when user opens item in page view. Is there a way to check it?
Or is there a flaw in my logic? I imagine list would update very fast because it doesn't require huge amount of data and also would modal/overlay because it recycles some of the data.
I read all the docs, also searched online - didn't find anything.
Modals in react router are great. I've used the pinterest example and adapted it to my own needs.
Ensure you do your check on state.modal===true in a master layout component to give you the modal styling.
you'll need to check if table 1 stuff is present in your state and dispatch an action to trigger the async call in componentDidMount. You should be fetching table 2 in all scenarios.
I just can't seem to wrap my head around Drupal relationships. I have been reading and watching tutorials, but as soon as I try to get my own project done - I fail. I think it's very basic, so I would love to understand it. Maybe someone here can help me understand how it works :)
On my drupal site, I want to keep track of some private game tournaments.
I have created a content type called contestant, which has fields like: Tournament date, Player name, Final Position. I can then create a view that list the information from one tournament. I used the help I got from this thread: drupal views dynamic filter
I would like to have the view described above as a block. And then place that block-view on a "tournament description" page. I could do this, by simply creating a new block each time, and then manually place it on the page it should be shown (structure-->Blocks-->configure), but that is not an elegant way to do it. I am pretty sure this is where Relationships should be used. But I fail to understand how to create this relationship, so that the specific block view, that matches the specific tournament description page will be displayed together.
Use a Content:Nid as a Contextual filter.
WHEN the Filter value is not in the URL >>
Provide default value
Content ID from URL
I have two lists of different PageTypes - NewsItems and PressReleases. They are displayed in one list each, with links to the individual items.
Now I want to include the press release items into the news list and use the style of the news items to display them as news items. They share properties like "Heading" and "BodyText", which are used in the News Template.
I imagine that it won't be that difficult to feed the NewsItems' ListPage with both sets of pages, but I don't understand how I can control the rendering of the item page.
I would like to take the PageData object from a NewsItem OR a PressReleaseItem and display it using the News-Item.aspx template, if it is selected in a NewsList. But EPiServer will always render the PressReleaseItem with the PR-Item.aspx since it's coupled in the PageType settings.
Anyone know how to accomplish this?
EDIT: An effort to clarify:
The important issue is how to know the "list parent" and choose the right template from that. In the ListPage I can apply different looks on the PR and News items respectively using tompipes answer, but when selecting to see an individual item EPi will render the PR-Item-1 the same way regardless of their "list parent". That's the problem.
I'm not following exactly what you are attempting here. But I think I get the gist of it.
Why not use one aspx template for both page types, but in the code behind switch off sections using the visible attribute.
If you are using PageTypeBuilder you could use the "is" keyword:
somePlaceHolder.Visible = CurrentPage is NewsItemList;
If you're not using PTB, you could use something like:
somePlaceholder.Visble = CurrentPage.PageTypeID == 10;
or
somePlaceholder.Visble = CurrentPage.PageTypeName == "NewsItemList";
I'll point out now I'm not a fan of hardcoding anything, so I would place the template name, or ID into a config file, or a property on the start/root page to avoid hardcoding them.
Let me know if this will help, or if I have misunderstood please try elaborate on your issue.
Depending on how much the templates share you could go with user controls, placeholders or even different masterpages to switch view in a suitable way.
To know when to switch you could use a querystring parameter, session variable or the nicest looking way would probably be to lookup and get the list's PageData object by the HTTP referrer. If it's empty you will get press release rendering as the worst case.
I tried lots of solutions, including the adding of querystring to the PR items in the list links, the getting of referring url in the item template and different types of event hooking for automatic publishing of news items from a PR item (although I only looked at the code samples for that one), and finally came to the conclusion that they all had something that told me not to go that way. (Making the code too complex, or the markup logic too hard to understand and so forth)
I ended up using Fetch data from another EPiServer page, and creating a "shortcut pagetype" in which I let my editors pick which PR item should be used as base for a news item.
This shortcut pagetype is called "PR-as-news-itemPage" and it is rendered with the same aspx as ordinary news items: News-Item.aspx. Having no properties of its own, it will take all relevant data from the PR item selected with "Fetch..."
To render PR items with all its properties I created an ordinary new pagetype called PR-Item.aspx. This renders the "Attribute 2" property, which is only rendered by PR-item.aspx, and not by News-Item.aspx.
(I could have gone even simpler, by letting the editors use the old News-Item page type and use the "Fetch..." property there, but I have some mandatory properties in that page type which I didn't want to make optional for this sake.)
In salesforce I need to create a visualforce page that includes the fields of 2 objects. The first object is the QUOTE object. The second objects is a custom object with several fields.
I want to create a visualforce page that shows the records of both QUOTE and the new object. Can I do this without creating a custom controller? If no any hints on the code for this new controller?
Can I do calculations between fields in a visualforce page?
Ideally I want this page to appear as soon as the QUOTE is set to ACCEPTED
1: You can't do this without a custom controller unfortunately, unless one object is related to the other and you're just happy displaying it as a related list on the parent object's page. For calculations you could use rollup summaries for some basic sums etc..
As for a custom controller, have a look at field sets for a super easy way to get fields into a VF page, you essentially configure groups of fields on your objects and then you can stick those groups onto a page with minimal markup.
2: For fields with complex calculations you'll want to do the sums in the controller and then expose the results through variables onto the page in the usual manner.
3: Not really possible without creating a custom edit page in the first place — you'd be better off having a button on the quote page to open up the Visualforce page, that page can simply display an error if the quote is not yet accepted. There are some other alternatives that might work though, like using a forumla field to generate a link to the page when the status is as you desire.
I'm happy to elaborate on any of this, but the fact that you're asking about number 2 would suggest to me that you don't have much experience developing on the platform (not a dig, just an observation), so unless you're comfortable coding in other environments you could find this quite tricky. That said, you're on stackoverflow so I'm thinking you probably know a little about coding at least!
