I need to present a content editor interface that allows editors to select specific pages in order to generate a link list for website visitors.
It seems treelist/treelistEX is providing the expected interface and I have combined that with a source path to lock the editors to a start destination rather than the entire sitecore tree. Opted for treelist EX as this appears to be the most efficient way as it doesnt render the tree in full each time unless its called upon.
In terms of the output however I'm getting a pipe separated list of GUIDs- is this something I need to iterate through manually using linkmanager or some such to obtain the items title and its sitecore link? Or is there an existing process that manages such a multi-list and breaks it up into its components.
If anyone can provide an example of that code and how to draw out the title and URL that would be great.
Thanks
There is no built-in solution for getting title and url from the items selected in Treelist.
You can treat your Treelist field as a Multilist field (they both store just list of pipe separated IDs in the background) and use GetItems() method:
Sitecore.Data.Fields.MultilistField treelistField = Sitecore.Context.Item.Fields["myTreelistFieldName"];
Item [] selectedItems = treelistField.GetItems();
foreach (Item item in selectedItems)
{
string itemName = item.Name;
string displayName = item.DisplayName; // fallback to Name if not set
string title = item["Title"]; // assuming there is a field called Title
string url = LinkManager.GetItemUrl(item);
}

I have a site that the user selects a drop-down menu item, inputs some JSON, and then clicks "Parse". Then the JSON data is checked against certain properties based on the drop-down menu item. Basically I have a list that looks like this.
myList = [{'Prop1': ['asdf', 'wefef']}, {'prop3': ['ss']}, {'prop2': ['d']}]
This is all the data I am checking against. It is the property name and then a list of expected values for that property name. Then in the JSON I have to compare those properties against the JSON properties in the list above.
Right now I am not sure where the best way to go about checking these. Should I do it in my views.py or should I do it in the page.html?
Basically I will need to look through myList and check if that property is in the JSON. If so then I need to check it against the expected property. And then I need to print things in a row so that you can view the info like:
Property Excepted Value Actual Value P/F
prop1 asdf, wefef apple F
prop2 d d P
prop3 ss sd F
My issue is, this will be a bunch of logic to build out to parse correctly. I am new to Django and not sure if the amount of code should be done in the HTML file. Else, I would need to build a large string in the views.py that contains all the data and the HTML, then pass to the HTML file and just display a single variable that displays all the data.
It is a good practise not to put too much logic in your page.html - it should just display your data. Therefore, put the logic into your view.
It also has the advantage that you can test the functionality way easier.
In my template I have a field type of Droplist which maps to a Sitecore folder holding values for the Droplist which in this case is Colours. This is so that an editor cannot make a typo or invent a colour this is not in the pre-defined list.
So that colour is based off a template I call TAGS which has a single field type of 'colour' and here I create a series of items using that template to create the colours for the swatch list.
When I access the main template I duly see the colour values in that Droplist so its working as I would expect it because I can access that fields values:
tileValues.Attributes["class"] += " tile-" + Item.Fields["Tile Colour"].Value.ToLower();
However I have realized its not using the field value of the template but rather the name I have called the item. SO its just a happy mistake that its achieving the result I wanted.
However how would I obtain the actual field value for that item in the end code. I have scenarios where there will be multi lingual editors so we may name the tags as rouge, blanc etc which is what the editor will see on selection in the Droplist but we need the colour value of the field to still say red or white etc
I tried:
Item.Fields["Tile Colour"].Item.Fields["Colour"].Value
But this failed despite the API hint implying its valid.
I hope this makes sense and someone can help me obtain the actual field value and not the items name.
As Sitecore Climber wrote, don't use Droplist field type - it stores item name only and you cannot get the item itself in the code behind.
Use Droplink field type - it stores ID of the item.
Then you can get the item:
Item colourItem = Sitecore.Context.Database.GetItem(Item["Tile Colour"]);
if (colourItem != null)
{
string colour = colourItem["Colour"];

Is there any way to sort the following items according to the days of week.
In C# I can do something like this:
string [] initialArray = {"Friday", "Monday", ... } ;
string [] sortedArray = initialArray.OrderBy(s => Enum.Parse(typeof(DayOfWeek), s)).ToArray() ;
But I don't know how can I achieve this kind of functionality with Sitecore.
If what you really care is to display the days sorted on the front-end regardless of how they are organised in the Content Editor then simply sort them in code before you display them, e.g.
using System.Linq;
var openingHours = Sitecore.Context.Item.Children
.OrderBy(s => Enum.Parse(typeof(DayOfWeek), s.DisplayName));
If you want to sort them in the Content Editor then you need to create a custom sorter. Sitecore Climber has provided links, but for this specific example you can use:
using Sitecore.Data.Comparers;
using Sitecore.Data.Items;
public class DayOfWeekComparer : Comparer
{
protected override int DoCompare(Item item1, Item item2)
{
var x = (int)Enum.Parse(typeof(DayOfWeek), item1.DisplayName);
var y = (int)Enum.Parse(typeof(DayOfWeek), item2.DisplayName);
return x.CompareTo(y);
}
}
Then in the core database create an item of item type /sitecore/templates/System/Child Sorting under /sitecore/system/Settings/Subitems Sorting and set the type to your class.
You should set the Subitem Sorting on the Standard values of a template. In this instance it looks like you have a simple Folder template, so you would need to create a more specific template for your Opening Hours folder. Even so, the user can still decide to re-order the items OR change the default sort for that folder. The only guaranteed way to force the output is by sorting before you render, i.e. the first bit of code.

I have a use case in which users need to select a field value from a droplist of items. The problem with this is that the droplist needs to be dynamically built on each item (all with the same template) to only show items in a folder that have a field value equal to that of the current item's ID. In case you're already lost, here's an example of the structure:
- sitecore
- content
- Home
- ContentItem1 (with droplist)
- Site Data
- SelectableItem1(ContentItem1 selected in 'itemid' field)
- SelectableItem2(ContentItem1 selected in 'itemid' field)
- SelectableItem3(ContentItem1 not selected in 'itemid' field)
- SelectableItem4(ContentItem1 not selected in 'itemid' field)
- templates
- ContentItem1Template
- Droplist field (source set to below query)
I want my query to assign the ContentItem1's droplist field source dynamically by getting a list of items that have ContentItem1's id as their 'itemid' field's value, but by comparing the field value to that of the ContentItem1 id. I have tried doing this by comparing the field's value to the id token, like so:
query:/sitecore/content/Site Data/*[##itemid#=$id]
No matter what value I try for id ('$id', $id, #id, '#id', ##id, '##id', etc.) it does not want to resolve on the item level. Is there some way to do this so that I can reuse this ContentItem1Template for all of my items that need the same functionality?
If you are using Sitecore 7 then you can use coded field datasources. This will allow you to use any custom logic you like to specify the items which should appear in your lists.
Create a class that implements IDataSource and the ListQuery() method that returns a list of Items as the source of your field. Then set the source of your field to your method with the code: prefix, e.g. code:MyProject.Custom.FieldDataSource,MyProject.Custom
using System;
using Sitecore.Buckets.FieldTypes;
using Sitecore.Data.Items;
namespace MyProject.Custom
{
public class FieldDataSource : IDataSource
{
public Item[] ListQuery(Item item)
{
var root = item.Database.GetItem("/sitecore/content/my-item");
// some other logic to filter your item set
return root.Children.ToArray();
}
}
}
These articles should help you:
Custom Classes as Data Template Field Sources
Having code as your field its datasource
You may need to wrap the ID in single quotes like so:
query:/sitecore/content/#Site Data#/*[#itemid='$id']
That said, this seems like a good fit for using the Sitecore Link Database. Whenever you associate a SelectableItem to a ContentItem, Sitecore will store that relationship in the Link database (as long as you reference it using a field that supports it, such as a DropLink, DropTree, GeneralLink, etc.).
From there, you can use Globals.LinkDatabase.GetReferrers(contentItem) or contentItem.Links.GetValidLinks() to get a list of all referring items to the content item. This is where you can filter down the list by template ID to ensure that you only return SelectableItems.
I would like to be able to store reusable html-formatted text in Sitecore and reference in codebehind for inclusion in a custom user control. What is the best practice for doing this? If a user selects option A, for example, I would reference standard text A in my control. Any examples for how to accomplish this are appreciated. Thanks.
You have a couple options:
Store the text in the Standard Values of the same template that defines your option list. That makes it available on the same item, but standard for all items. Use security to lock down the field if you are worried about it being edited. This could also be accomplished with the new "cloning" feature in 6.4, I believe.
Create a structure outside of your Home element for storing this data. Based on the option selected, find an item in your content tree which corresponds to the selected item, and read the text off of it. You would need to find this item either relative to /sitecore/Content, or relative to your website root if multi-site support is a requirement.
No.2 in pseudo-code:
//get the item where we have the text values
Item textBase = Sitecore.Context.Database.SelectSingleItem(textBasePath);
//find the child w/ the same name as the selected option
Item textItem = textBase.Axes.GetChild(selectedOptionValue);
string value = textItem["text"];
I think I would do something like techphoria414's 2. option:
ie you have your normal "page" templates as per usual, but then you have some fields (multilist, treelist fields), where you put the source pointing to your other items contain the different texts.
then you basically just have to get the items from the current item (with some very quick'n'dirty code/pseudocode):
var CurrentItem = Sitecore.Context.Item;
Sitecore.Data.Fields.MultilistField mlf1 = CurrentItem.Fields["myExternalTexts"];
if(mlf1 != null)
{
foreach (Item itm in mlf1.GetItems())
{
lit += Sitecore.Web.UI.WebControls.FieldRenderer.Render(itm, "richtext");
}
}
You ofc shouldn't just add them to a literal and you should you Sitecore built in Field renderes if using Sitecore 6 or above and it's a Rich text field.
I hope that helps.
