I have added a field (media picker field) for "BackgroundPhoto" to the Page content type.
I'm trying to get the page so when that field exists, or has a value, that it's added through css as the background URL to the layout-wrapper found in layout.cshtml.
I have searched and come close to finding how this works, but never accessing a value from a content type on the layout page. Does anyone have an example where this works? Specifically, a value in a page field is added to the "layout-wrapper" item in layout.cshtml.
Thanks for your help!
Technically, the layout wrapper is document.cshtml. You could override that to render a value that you stored in HttpContext from your deeper field template.
To recap: create a template override for your field in your theme; from there, set the value of the field into a HttpContext item; From document.cshtml, retrieve and render that value.

I would like to display certain first level menuitem in bold.
This setting should be done by a checkbox when the user create / edit a menu item. (I have a workaround using the Model.Href, but it is not nice).
So I created a boolean field in Content definition / Menuitem URL (I don't know the name of the corresponding content definition in English Orchard).
How to access a custom field (Content Field) from a view?
(There already is a view which is used to customize the menu)
The examples I found use custom shapes, where the fields are accessed as built in fields (e.g. Model.ContentItem.FieldName ). But this is a different case.
With the help of "Piedone", the solution:
Model.Content.ContentItem.MenuItem.FieldTechnicalName.Value
Explanation
Examining the Model object in Visual Studio, the Model is a dynamic shape that have eg. Href property and a Content.
Content is a MenuPart, that is a content part that have a ContentItem property with the content item itself. Technically only content parts have Fields. When you (seemingly) add a field to a type it will be a part corresponding the type's name, that is MenuItem in this case (It's confusing that the display name of 'MenuItem' content type is Custom Link...)
The field's technical name is as you name it. When you add to a type, the Value will be a property of the BooleanField class. (By the way, it is nullable, so if you dont't save after adding the field, it will be null else the value you set).
I am creating a page template. Each page using the template will have a single unique value that gets embedded into the page HTML. The rest of the HTML is constant for all pages. Assume the following is the desired result:
click me
I want a template that provides click me, while allowing the individual pages (content admins) to provide id.
I've tried using an Editable Text web part, and putting the "before" and "after" HTML in the HTML Envelope before and after sections, and adding the ID on the "Page" tab. However, that is not quite working. What is the best way to accomplish this?
This can be done. What you'd want to do is add that field to the page type fields you're adding those pages with. For instance, say you have a list of locations under /locations.
i.e.:
/location/chicago
/location/new-york
/location/minneapolis
The locations themselves (Chicago, New York, Minneapolis) are your custom page type and have a unique field called LocationID. On your template, add a static text webpart (not static HTML because the WYSIWYG editor overwrites the markup you add) and simply add this:
click me
If the LocationID field has a exists AND has a value, it will output it, otherwise it will just leave the URL http://www.example.com/
If you didn't want to show that link at all on other pages, then set the Show for page types property based on the page type you want it to show for in the Visibility section of the static text webpart.
I'm reading through the documentation (https://docs.kentico.com/k9/managing-website-content/configuring-the-environment-for-content-editors/configuring-tags/allowing-users-to-tag-pages-on-the-form-tab) and thought all was good, but when i go to create a new page based on the pate type, my Tag field is greyd out.
At the bottom of documentation page, is states:
If you need to create a custom page type with a tag selector, the tag selector must be bound to a system field
I don't know what this means? I've created a tag group (Global), but I'm stuck.
If your parent page type has the Tag field in it already, the child page type will not allow you to change it, you have to go back to the parent page type to change any attributes about it.
Binding that tag selector to a system field means when you create that field, you need to select system field when you create it vs. a standard field.
In orchard, I've added a boolean field called "IsDone" to the built in Content Menu Item content part via that Admin interface. I've then picked an item in Navigation and set the option to "yes" for the corresponding field i added.
In my custom theme, I've copied over MenuItem.cshtml.
How would I get the value of my custom "IsDone" field here?
I've tried something like
dynamic item = Model.ContentItem;
var myValue = item.MenuItem.IsDone.Value;
but I'm pretty sure my syntax is incorrect (because i get null binding errors at runtime).
thanks in advance!
First i suggest you use the shape alternate MenuItemLink-ContentMenuItem.cshtml instead of MenuItem.cshtml to target the content menu item directly.
Secondly, the field is attached to the ContentPart of the menu item. The following code retrieves the boolean field from this content part:
#using Orchard.ContentManagement;
#using System.Linq;
#{
Orchard.ContentManagement.ContentItem lContentItem = Model.Content.ContentItem;
var lBooleanField = lContentItem
.Parts
.Where(p => p.PartDefinition.Name == "ContentMenuItem") // *1
.SelectMany(p => p.Fields.Where(f => f.Name == "IsDone"))
.FirstOrDefault() as Orchard.Fields.Fields.BooleanField;
if (lBooleanField != null)
{
bool? v = lBooleanField.Value;
if (v.HasValue)
{
if (v.Value)
{
#("done")
}
else
{
#("not done")
}
}
else
{
#("not done")
}
}
}
*1
Sadly you cannot simply write lContentItem.As<Orchard.ContentManagement.ContentPart>() here as the first part in the part list is derived from this type, thus you would receive the wrong part.
While #ViRuSTriNiTy's answer is probably correct, it doesn't take advantage of the power of the dynamic objects that Orchard provides.
This is working for me but is a much shorter version:
#Model.Text
#{
bool? IsDone = Model.Content.ContentMenuItem.IsDone.Value;
var IsItDoneThough = (IsDone.HasValue ? IsDone.Value : false);
}
<p>Is it done? #IsItDoneThough</p>
You can see that in the first line I pull in the IsDone field using the dynamic nature of the Model.
For some reason (I'm sure there is a good one somewhere) the BooleanField uses a bool? as its backing value. This means that if you create the new menu item and just leave the checkbox blank it will be null when you query it. After you have saved it as checked it will be true and then if you go back and uncheck it then it will have the value false.
The second line that I've provided IsItDoneThough checks if it has a value yet. If it does then it uses that, otherwise it assumes it to be false.
Shape Alternate
#ViRuSTriNiTy's other advice, to change it to use the MenuItemLink-ContentMenuItem.cshtml instead of MenuItem.cshtml is also important.
The field doesn't exist on other menu items so it will crash if you try to access it. Just rename the .cshtml file to fix this.
Dynamic Model
Just to wrap this up with a little bit of insight as to how I got there (I'm still learning this as well) the way I figured it out is as follows:
.Content is a way of casting the current content item to dynamic, so you can use the dynamic advantages with the rest of line;
When you add the field in the admin panel it looks like it should be right there on the ContentItem, however it actually creates an invisible ContentPart to contain them and calls it whatever the ContentItem's type is.
So if you had added this field to a Page content type you would have used Model.Content.Page.IsDone.Value. If you had made a new content type called banana it would be Model.Content.Banana.IsDone.Value, etc.
Once you are inside the "invisible" part which holds the fields you can finally get at IsDone. This won't give you the actual value yet though. Each Field has its own properties which you can look up in the source code. the IsDone is actually a BooleanField and it exposes its data via the Value property.
Try doing a solution-wide search for : ContentField to see the classes for each of the fields you have available.
Hopefully this will have explained things clearly but I have actually written about using fields in a blog post and as part of my getting started with modules course over on the official docs (its way down in part 3 if you're curious).
Using built-in features instead of IsDone
This seems like a strange approach to do it this way. If you have a Content Item like a Page then you can just use the "Show on a menu" setting on the page.
Go to admin > content > open the page > down near the bottom you will find "Show on a menu":
This will automatically put it into your navigation and then you can move it around to where you want:
After it "IsDone" you can just go back and untick the "Show on a menu" option.
Setting up the alternative .cshtml
To clarify your comments about how to use the alternative, you need to
Copy the file you have at Orchard.Core/Shapes/Views/MenuItem.cshtml over to your theme's view folder so its /Views/MenuItem.cshtml
Rename the copy in your theme to MenuItem-ContentMenuItem.cshtml
Delete probably everything in it and paste in my sample at the start of this post. You don't want most of the original MenuItem.cshtml code in there as it is doing some special tricks to change itself into a different shape which isn't what you want.
Reset your original Orchard.Core/Shapes/Views/MenuItem.cshtml back to the factory default, grab it from the official Orchard repository
Understanding the view names
From your comments you asked about creating more specific views (known as alternates). You can use something call the Shape Tracer to view these. The name of them follows a certain pattern which makes them more and more specific.
You can learn about the alternates on the official docs site:
Accessing and Rendering Shapes
Alternates
To figure out what shape is being used and what alternates are available you can use the shape tracing module which is documented here:
Getting Started with Shape Tracing
I have created a custom field type as it is there in sharepoint OOTB, the difference is only that the end user does not need to check the name i.e I have replaced it with DropDownList. The dropdownlist suggest the no. of users available in the web site for that I have created a FieldClass which inherits from SPFieldUser and a FieldControlClass which inherits from UserField. It is working fine in all conditions i.e when I create a List or Document Libarary it shows me the DropDownList
with respective users after saying OK it creates an item for me. I have overriden a Value property in FieldControlClass as follows,
public override object Value
{
get
{
SPUserCollection userscollection = rootWeb.SiteUsers;
//ddlInfoBox is a DropDownList to which I have Binded the collection of users in the form of string
SPUser user = userscollection.Web.EnsureUser(this.ddlInfoBox.SelectedValue);
SPFieldUserValue userval = new SPFieldUserValue(user.ParentWeb, user.ID, user.LoginName);
return userval;
}
set
{
SPFieldUserValue userval = (SPFieldUserValue) this.ItemFieldValue;
this.ddlInfoBox.SelectedValue = userval.Lookupvalue; //Here look up value is nothing but a Login name e.g In-Wai-Svr2\tjagtap
}
}
Due to above property the Custom Field's Value for this current ListItem will be stored as SPFieldUserValue e.g 27#;In-Wai-Svr2\tjagtap.
The main problem is here, when this particular ListItem is shown in the list page views e.g on AllItems.aspx or the custom view pages associated with it, it shows the
number as 27 as a FieldValue insted of HyperLink with text as "In-Wai-Svr2\tjagtap" and PostBackURL as "/_layouts/userdisp.aspx?ID=27".
When I edit this Item it makes the respective value selected in the dropdownlist, also while viewing this item i.e on DispForm.aspx it also shows the hyperlink. I have
acheived it by writting a custom logic in createchildcontrol() method i.e by using ControlMode if it is New or Edit then fill the dropdown list, if it is Display then get the ItemFieldValue Type Cast it into SPFieldUserValue and get corresponding lookupid and value for making the URL and showing Text of the HyperLink.
I have spent a lot of time on searching and bringing the HyperLink as the user name with navigation insted of UserID (27) as a string on the list view pages e.g AllItem.aspx but to no avail, then after a lot of research I found that there might be a way of achieving such kind of functionality by using field type definition xml file where there is a provision to define a DisplayPatteren as you wish by specifying the html code. But here is a problem How can I get the UserID (27) with respective UserName e.g In-Wai-Svr2\tjagtap inorder to make an anchor tag like In-Wai-Svr2\tjagtap which will solve my problem. I have hard coded this anchor tag within the Default case statement of a switch under DisplayPatteren but it shows me the field value on AllItems.aspx as
In-Wai-Svr2\tjagtap27 i.e the value defined in xml file is concatenating with the string value (27).
Please help me to resolve the above mentioned 2 issue. I am really in need of solving this problem ASAP.
Thanks & Regards,
Tejas Jagtap
Have u tried to override the GetFieldValueAsHtml() method in the the custom field class or maybe the RenderFieldForDisplay() method in the custom field control class.
Can you use the DisplayPattern CAML from the User field type?
